Hi,Dongguan Pnjie Optronics Co. Ltd--LED light manufacturer, offering al kind of led light, such as, led bulb, led spot light, led tube, led ceiling light with CE, RoSH,FCC listed. And also we can be your OEM, pls talk to me if you interestin in our company.
There are actually more things to consider when choosing the right lamp. eg CRI, Upon researching, you'll realize that incandescence has the best CRI followed by fluorescent and finally LED. It's also not true that LED dissipates less heat. In fact they dissipate about 85%+ of the input power as heat (refer to the case study by IEEE: google seach t5 vs led (the first website you see)). Interestingly, one of the case study also showed that as the heat increases, LED lifespan can drop by 50%!
hello,this is Rain from Ledlighter factory in China,if you need to buy led products just contact me,mail/MSN/Yahoo:shushucao000@yahoo.com.cn,Skype:rainluo1984
There are so many LEDs from many manufacturers claiming same things. I represent a simple lighting company. Yet the customer demands technology which can be applied by many vendors - SEAK Energetics
The test has one major flaw. Many of the LED tubes are positioned directly under the lux meter, thus the lux reading would be higher. If the LED tubes were positioned where the flourescent tubes where I would be interested to see what lux reading you get then.
LED is the way forward however the industry is not doing themseves any favours. One supplier quotes a lifespan of 50,000 while the other quotes 100,000 hours for the same product!?Industry standards need to be set.
@laughinglawly Very true, I for one can't wait to replace almost ALL of the bulbs around me with LED....Brighter, safer, cheaper to run....yes please!
There is no reason that led's shouldn't completely overtake all other forms of lighting. There is even led bulbs for stadium lighting now...talk about saving money for the team....
@areodynamic1 LED lighing may be useful for some forms of lighting but you clearly don't know about all forms of lighting, there are several I can name off that are considerably more efficient than LED and LED for stadium lighting, in your dreams!
Electricalproducts com au is an Australia's specialist supplier of all electrical products ranging from Pendant Lighting, Fluorescent Lighting, Downlights, Spotlights, Track Lighting, Oysters, Wall Lights, Ultra Violet Lighting LED Products, Hunter Pacifiic,etc.
LEDs have been implemented in emergency lighting, general lighting and decorative lighting, particularly by using colour-controlled LED lighting modules. Visit electricalproducts com au for details
Energy efficiency in lighting conditions follows the same formula for all energy calculations. The law of conservation states that the input is equal to the output. IE if three lights are each given the same amount of energy in, there will be equal amounts of energy out.
Imagine you give 75 watts each to three light sources. The incandescent will output tue least amount of light and the most amount of heat.
The florescent will output more light and less heat, whi
CORN bulb had 108 led at 360 degrees and it compatible with all home bulb lamp , it produce 650 lumens and consume only 3.8 watts ..and it so cheap only 5$ , this are the future , i'm very impressed with my new 108 L.E.D and your TEST prove L.E.D are th best light source at ultra low consumption
Energy can not be created nor destroyed, it is rather converted into different forms. You cannot put in a lower amount of energy and get a larger amount of energy out of it. I don't know how to determine what that electrical energy is being converted into with accurate measures. Example:
The wires in a toaster oven give off light which is inefficient because the main purpose of the heating element is to use the electrical energy to produce heat but it wastes some of it creating light.
Studio lighting and road works emergency lighting is using LED's now. The light is bright and sharp and can be run from a car battery instead of a 10kw portable tow geny.
I doubt that the LEDs put out much more heat than fluoros.
It's basic physics - the energy that they draw from the power supply equals the total energy that they radiate. If the LED is brighter and uses less electricity, then it must be radiating less non-visible energy such as heat and UV.
It follows that either the LED is cooler than the fluoro tubes, or the fluoro tubes are emitting a heck of a lot of UV light.
I'm willing to bet the LED's produced more heat, and as such, the heatsink on the rear would have been quite substantial.
Thats the problem with larger LED modules, the heat they produce at the rear are far more than fluorescents, and the trouble is being able to dissipate that heat.
@SecksJay well you might talk about these high power LEDs who indeed become hot and need heatsinks, like these high power LED Spotlights. Normal LEDs actually don't get warm at all.
LED's don't contain mercury and they're brighter = Automatic win.

Those preheat fluorescent's have a much nicer startup than the 'instant on' LEDs
Maybe in a commercial building the LEDs would be good for energy saving...at
home i'd take the fluorescent.

I am anxious to see LED's used as full lighting. Flourescent lights give me extreme migraines and dizziness within a halfhour.

@greenlimer That's probably because of the radiation the Fluorescent lights emit.

Sir, In Fluoro Argon Gas which is inert is used, so the heat is unchanged.
