Reviews & GuidesLED Bulbs: Know Before You BidThinking of purchasing LED light bulbs for your home or office? This article presents three important facts about household LED bulbs sold on eBay, and could prevent you from making a costly mistake! It's a light bulb that can stay turned-on 24 hours a day, 365 days a year, it will last for years... and unlike any other light bulb in existence, it's likely that the electricity required to operate this bulb for its entire life will cost you less than the price of the bulb itself. This is the promise of LED light bulbs that run on normal household current. Whether the interest is in "saving the planet" or just saving a few dollars on the household budget, LED bulbs are rapidly growing in popularity. Unfortunately, some consumers of household voltage LED bulbs, like those currently being sold on eBay, are finding out the hard way that these bulbs are still a long way from being suitable for most household uses. In some cases, the bulbs simply do not produce the type or level of light that is required for normal room illumination. In other cases, people find that these bulbs -- most of which are mass-produced in China -- are not built to the quality standards that should be expected of a household product. This article serves to alert you to three important facts about currently-marketed household LED bulbs. These are factors that require serious consideration, especially if you're thinking about making an outright changeover from incandescent or compact fluorescent lighting to LED lighting in your home or business. Please note that this article focuses specifically on household bulbs, not bulbs sold for automotive use, landscaping or other special purposes. Compact Fluorescent Bulbs; A Beginners Guide.Introduction: Light Bulb GlossaryNow that you have selected the perfect lighting fixture, this helpful glossary of light bulb, or lamp, options will easily guide you towards finding the correct light bulb for your lighting selection. Although light bulbs are fairly basic in function, there are so many options that can leave you uncertain. This useful guide is designed to ease your confusion and direct you towards the perfect light bulb. Compact fluorescent light bulbs are commonly used in desk lamps, floor lamps, undercabinet lamps, table lamps, linear strips, wall sconces, flush mounts, chandeliers, close-to-ceiling or flush mounts, pendants, ceiling clouds, kitchen island lights, path lights, outdoor wall lanterns, outdoor post lanterns, as well as outdoor wall and ceiling mounts. Compact fluorescents can not be used in motion sensor fixtures or lights with a dimmer switch. Types: Plug-in Base CFL Anatomy of a Full Spectrum Neodymium Light Bulb A full spectrum Neodymium bulb is an ordinary incandescent light bulb, except that the glass shell is infused with the rare earth mineral element Neodymium, which is baked into it. It gives the glass a bluish/purplish/lavender tint. Some manufacturers avoid the more expensive and preferred fusion method of baking the Neodymium into the glass, and just apply a mixture containing some Neodymium, as a coating to the inside of the glass shell, much like that of the "frosting" applied to a frosted light bulb. This coating can be uneven and also separate from the glass, creating an inconsistant dispersion of the filtered or purified light. The fusion method also prevents the Neodymium from flaking away from the glass over time, regardless of how hot the bulb gets. The Neodymium filters out the excess yellow light produced by standard incandescents, but doesn't remove it completely. As a result, it brings out the truer color of objects, providing bluer blues and redder reds. Neodymium gives the light a bluish tint(enhanced white light), as it attempts to create a color spectrum as similar to that of the sun as possible. Colors are brighter and more vibrant. Skin tones appear natural, and visual acuity increases. It also reduces glare, which minimizes eye strain and fatigue. These bulbs greatly reduce the overwhelming and depressing yellow effect produced by regular standard light bulbs. There is a difference between incandescent and fluorescent lighting, and incandescent Neodymium bulbs should only be compared to, or measured against the incandes... SAD and Full Spectrum LightingSeasonal Affective Disorder (SAD) is caused by the lack of proper light during Fall and Winter months. The darker days signal the brain to overproduce the hibernation hormone, melatonin. Also, without sunlight, the brain doesn't produce enough serotonin, which results in the symptoms of depression. Medical experts and researchers have documented the causes and symptoms of SAD for over twenty years. Full Spectrum Light Bulbs come as close to man-made sunlight as is technologically possible. However, you must be sure you are buying the correct FULL SPECTRUM bulbs. Bulbs that produce almost 1,600 lumens of full spectrum daylight, 5500 degree Kelvin and 90 CRI are the closet replication of natural sunlight available. Full Spectrum Bulb Guide to Buying Silicone/Flicker BulbsIt is a regular glass bulb dipped in a silicone mixture. It is rubbery to the touch and kind of spongy feeling. Are you trying to light a whole room or just need accent lighting? Do you want a bulb that stays constant or one that flickers? Do you want a colored bulb? Keep in mind the requirements of your particular lamp or night light by looking at the base size (the metal part where you screw the bulb in), bulb wattage (brightness of light) and actual size of bulb. Everything else would depend on the "look" you want. How large do you want the bulb to be? Generally there is a "curly cue" on the top, which is silicone, and helps make the character of the bulb so unique. It is kind of like a Dairy Queen ice cream cone curly cue. It is flexible to the touch and silicone rubbery feeling. When inquiring about the bulb measurement, ask if it includes the "curly cue" at the top. History of Hydroponic cultivationHistory
Contrary to some modern sources, ancient peoples such as the Babylonians and Aztecs did not use hydroponics. The mineral nutrient solutions required for hydroponics were not developed until the 1800s. The so-called Floating Gardens of the Aztecs (chinampas) used soil. The Hanging Gardens of Babylon were supposedly irrigated roof gardens but there is no evidence they used hydroponics.
The earliest published work on growing terrestrial plants without soil was the 1627 book, Sylva Sylvarum by Sir Francis Bacon. Water culture became a popular research technique after that. In 1699, John Woodward published his water culture experiments with spearmint. He found that plants in less-pure water sources grew better than plants in distilled water. Mineral nutrient solutions for soilless culture of plants were first perfected in the 1860s by the German botanists, Julius von Sachs and Wilhelm Knop. Growth of terrestrial plants without soil in mineral nutrient solutions was called solution culture. It quickly became a standard research and teaching technique and is still widely used today. Solution culture is now considered a type of hydroponics where there is no inert medium.
In 1929, Professor William Frederick Gericke of the University of California at Berkeley was first to suggest that solution culture be used for agricultural crop production. He first termed it aquiculture but later found that aquaculture was already applied to culture of aquatic organisms. Gericke created a sensation by growing tomato and other plants to a remarkable size in his backyard in mineral nutrient solutions rather than soil. By analogy with the ancient Greek term for agriculture, geoponics, the science of cultivating the earth, Gericke introduced the term hydroponics in 1937 for the culture of plants in water (from the Greek hydros, water, and ponos, labor).
Reports of Gericke's work and his overzealous claims that hydroponics would revolutionize plant agricultu... Fluorescent Lamp, Energy Saving (34 watt, 4' feet)Hmmm, I got another problem and solution for you! Well, I have see many times when people do mistakeability about using old model energy saving fluorescent lamps like 34 watt, 4' foot (48" inches), T-12 bulb. I totally surprised that lamp was not good enough to perform lighting. Since these lamp was introduced in late 1970's by whom owned laboratories. Hey folk please keep the mind, this is your lamp strategy test but I'm challenging you see if you get this right from my testimonial (if, its true, please, vote for me by 'yes'). Okay, are you ready?... Here is.....Study carefully. Start with caring performance using T-12, 34 watt, 4' foot lamp. Lamp only like to keeping real warmer air on bulb wall (my temperature like 74 F degrees for best describe brightness but never closer to A/C vents) for the best result at 77 F degrees for normal brightness, keep away from A/C (I'll tells you why?). Most manufacturers for those lamp can reliable at 60 F degree and average of life goes up to 20,000 hours, tested in 4 hours per start per daily (some people said that doesn't that long enough) and must uses in electromagnetic rapid-start ballast only (can be used in electronics ballast, be specify on ballast label where can be meet standard CSA, UL, etc...). Also do not uses in electronics dimming ballast (result lamp won't work on it). It can be excellence at your work place, public school, small business porportion, etc... Designing for this lamp, must be used in commerically, run for couple hours per daily. Now, I'll tells why, you should never place your lamp closer to A/C (air-conditioning). Because of this lamp wall make cooling off, light output become loosening, some can causing slightly shimming, likely turned out. Inside of fluorescent where electron flowing through tube, when bulb wall temperature is decreasing which the electron will shrink... Using CFLs magnetic ballastsHi, I'm expert lighting man. As you know what I have learned and tested some lighting material for over the years. As well as my professional handed all my lamps testify. I will teaches you how to survives your lamp life or equipped with lamp. You must do exercises with this caring with your purchased following magnetic ballast case(s) or a self-magnetic ballasted screw-in pieces. All expenses, I rather paid to do my work for you (Huh???). Just thinking about it... WARNING!: All plug-in style, 2-pins, any wattage compact fluorescent lamps. When lamp come to ended of life, it will continueously flickering in causes heating up ballast (resulted in shorten ballasts life). Please, RELAMP as soon as possible or before too late... Somewhat likely starting fire, blow-out ballast and lamp at same time (some in cases). Otherwise, saves your ballast life as well maintainence in lighting fixture. If you have a magnetic self-ballasted screw-in with replaceable plug-in lamp, DO NOT uses in totally enclosed fixture, resulted in plastic molded turns yellowish to brownish (model in white or ivory color body), some possible going to melting and overheating ballast/ or lamp, both at the same time as well. Make sure you MUST read the follow instruction comes with every compact fluorescent retro kit or universal kit before installed in your fixture. Some self-magnetic ballasted screw-in pieces rating an avg. life up to 40,000 hours at room temperature (77 F degrees) and relamp as soon as possible as well handled up to 4 replaceable lamp lives). Some of it can be uses outdoor (only available in 5,7, or 9 watt lamp should handle in cold temperature stated in minim... Reasons to use energy efficient CFL bulbsCompact Fluorescent Lighting Guide for Businesses The way some business owners and/or corporate buyers react to compact fluorescents astounds me. It is almost as if they don't believe the facts about energy efficient lighting. There are alot of misconceptions about the use of compact fluorescent light bulbs. I would like to address those misconceptions in this guide. The advantages of using CFL: 1. Reduce your light bulb replacement cost. A CFL lasts up to 10 times longer than a standard light bulb. Because they last longer, you buy less of them. By replacing bulbs less often you really do save money. You also save the time it takes to replace the bulb, and you save the time of going to the store for bulbs. 2. Reduce your electricity consumption. A 25 Watt CFL that replaces a 100 Watt Halogen can save 800 kilowatt hours. At 10 cents per kilowatt hour that amounts to $80 in savings over the rated life of the CFL bulb which typically lasts from 5,000 to 10,000 hours. 3. Reduce greenhouse gas emissions. Help slow down the warming of the planet. Your going to the store less, so you're not using gasoline. The electric company power demand is less, so less fossil fuels are burned to produce extra electricity. Misconceptions: 1. The CFL takes too long to warm up to full brightness. New CFL technology is available that eliminates that problem. Really! 2. The CFL has an ugly yellowish glare. New CFL technology is available that eliminates that problem. Really! A wide range of color tones is available. Remember to use the right color tone for the right lighting application. The newer fluorescents have many different color temperatures. From 2700K all the way to 6700K. The higher color temps light the entire spectrum of... LED HOUSEHOLD SPOTLAMPSI HAVE PURCHASED THESE BULBS FROM A FEW VENDERS AND FIND ALL HAVE THE SAME PROBLEM. THEY SIMPLY DO NOT WORK VERY LONG---SOME ADVERTISE THAT 80 TO 100 THOUSAND HOURS--------THIS IS LAUGHABLE AS OUT OF 20 BULBS NOT ONE HAS LASTED MORE THAN A MONTH OF OCCASIONAL USE. I DEFINATELY COULD PUT THESE TO GOOD USE,BUT THEY ARE VERY SHORT LIVED AND CONSIDERING COST YOU WOULD NOT SAVE ANYTHING AND IN FACT CONSIDERING COST--- YOUR LIGHTING EXPENSE WOULD BE MANY FOLD HIGHER. THIS IS WORDS FROM EXPERIENCE. Bulb Size! What Size is Mine? The code number of a bulb consists of a letter or letters followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch.
The most commonly used household bulb is the A-19. The bulb is "A" type and the diameter would be 2 3/8" A 120BR40 is a 120 watt reflector 5" in diameter. &... FAQ's on compact fluorescent light bulbsHow does a compact fluorescent light bulb work? What's the difference between a compact fluorescent light bulb and a fluorescent bulb? Fluorescent Lamp, Energy Saving (60 watt, 8' feet)Hmmmm, interesting about using energy saving 8' foot lamp.Well, this lamp seems it alright but depending on what kind lamp are you using it. Some has good efficiency energy and brightness effect. Anyway, this is your stragey test but I'm challenging you sees if you get this right thoughts. Otherwises if you decide to do your own budget or save your money to buy. Okay, its time for knowledge begins... Knowing about 8' foot (96" inches), 60 watt energy saving, single pin lamp. This bulb requires using in slimline ballast (instant starts) either 1 or 2 lamps (series circuit) which available and also an available electronics instant start either 1 or 2 lamps (parallel circuit). The averaging life is 12,000 hours (lab tested 4 hours per start per daily), lamp operates in best results at temperature 60 F degrees. Yet, this lamp is too long but be very careful about breakage (yeah I know it is big messes). Only I know this lamp comfortable in vey warm air stability which best describe brightness from initialize lumens (light output), I has this good about 75 to 77 F degrees (but it is okay goes more warmer which I stated). Therefore the old exist lamp were made 75 watt (standardized wattage) can be operates at 50 F degrees and 10 to 15 % brighter than energy saving lamp which initialize lumens stated. Both lamps can be great place in like warehouse, commerical store, workout gym, etc... Please reguardly about order single pack per bulb will increases risk of breakage otherwises must have ordering in case of 10 to 15 bulbs (or each cases) to reducing breakage or few will breaks, since 8 foot long packages can be too heavily and needed 2 people carry but not be one person carry by dragging the case(s) in some bulbs going to break as well. Of course insuranc... Circular Fluorescent Lamp (Circline Bulb)Hi folk! Got another one! I'm lighting experters and knowledges. Ahhh... Good ol' day of art deco light fixture came with circle fluorescent lamp. Remembering that? Of course, do you... Well, it's classical as today but they don't make them anymore as vintage fixture. Although the only they still make them with different style of collectors, designer, or reproductives in the today model (currently). In spent time to shopping in the eBay, which seller was oftening the lower or higher value price (may be worthy). What I have today with you, guy. That are... Checking the wires aging, replacing lamp, ballast type, and whatelse. Good luck! Okay, first up. When you are planned to purchasing from seller. You needs carefully describe from seller's picture where you see clearly. Sometimes they do get mistake where you got them or whether not sure if appearance condition or worthy. When seller can performances a light fixture to lit up (seller shown picture), you knowing that bulb is working. Now, any thing can happen. Just what might be... The wires age! How that possibles... Many people don't know why the seller handed picture inside of light fixture could be that too old to reuse the wire (let's saying that over 50 years old). Do you think that safe to reuse them? Answer is sometime... Because, if unless it is okay to reuses wire as long you needed to be careful handling those wire while ready to installed properly. Most of art deco (or a vintage) circular fluorescent light fixture started made from early in 40's, the cloth wire came with fluorescent ballast usually made in between 30's to 50's, plastic wire in 60's to beyonding. I strongly suggestion that you should be replace ballast with originally wire as well bein... Compact Fluorescent Lamp Fallen?!!! Repair TipsHi folks! I'm doing technical lamp for years and still experters lamp handed as well. As you know I've been collecting light bulb for over 20 years. My goal is studied carefully all parts of lamp and maintainance lighting. Where I know what I have done for years and now its time to tell all!!! Trusted me, everything what I got from information whom to everybody else and of course I was looking at light fixture in about everywhere includes warehouse, super market, etc... By knowing what causes lamp operating. Also I took some status and notes from any reasons, problem, troubleshoot, etc... Today, I talking about what do you know when compact fluorescent lamp fallen out of light fixture. Yes folk, this is can happen quite oftens. In most of compact fluorescent lamps, includes electronics dimming, electronics 4-pins, magnetic 2-pins, and about every plug-in lamps. If you looking at a centering, recessed light fixture (downlighted) where you don't have lenses, usually lamp could be fallen (some results hitted from a personal likely injury, some has been falling which landed in shattered glass on the floor). But those who has lenses which doesn't hurt lamp basically lamp dropped on the lenses (lenses doesn't secure in which results fallen as well). Please notice that you have lamp faced horizonally (laid flat) which you can not seen a light socket. It must be removing trim, reflector pan, and other accessories which fixture came with it when after installation (REMEMBERING! you should always keep a manual instruction for any further and where you got them). RELAMP SAFETY!!! For those using most of compact fluorescent 2 to 4-pins lamp. It is most important you should be wearing safety glasses and soft cloth ... What Kind Fluorescent Lamp Starter Should You Using?Hi, I'm expert lighting man in over the years. I have been learned and testified any lighting materials. Many kind fluorescent starters could causes some customer confusing and mistakeable. Please pay close attention!!! Otherwise someday you will be professional electrician needs extra care and effort. All my answers, I have been where result by using these fluorescent starters. All expenses, I paid off working just for you. Huh?!!! Of course, I will tells you right now. Here is.... Okay, I mentioned early pervious guide ( I wrote in "Using CFLs magnetic ballasts" column). Here you should needs read carefully entire fluorescent starter package or carton box come with it but that not enough information on it. Right?!! Well, as you know there is type of starter, FS-2, FS-4, etc... and the wattage mentioned on their body of starter, that for matching fluorescent lamp (if specify lengths as given). First up, every fluorescent starter should have condenser inside, this is for charged glow switch bulb which make contact enclosed and heat up cathodes on fluorescent lamp both ended while releases contact and lamp begins lit up. Some stated without condenser, it may not work with fluoresent lamp to light up. Condenser is made up of mylar filmed capacitor, but sometime made with waxing filmed as well, some has rated or may not rated. Condenser is a best result used. Please notice additionally information in fluorescent lamp ballast should be using pre-heat circuit type magnetic ballast or pre-heat magnetic ballast needed starter requirements. If trigger-start magnetic, rapid-start magnetic, rapid-start electromagnetic, rapid-start electronics, and instant-start electronics ballast does not need... |
Compact fluorescent is a generic term used for a variety of bulbs. CFL's use less 20-40% energy to produce more light per watt and are color adjusted to produce light close to real sunlight. CFL's generate less heat and offer a longer life than incandescent bulbs, saving you money on electric bills and protecting the environment from harmful greenhouse gas emissions. Look for Energy Star labels on fluorescent fixtures and lamps for assurance of maximum savings, quality and standards.
