Efficiency: 110 LPW( lumens per watt).
LEDs produce 80 lumens per watt; traditional streetlights can only muster 58 lumens per watt.
Their goal is efficiency higher than 100 lumens per watt.
There is a big difference in lumens per watt between blue LEDs and white LEDs.
High power SMD LEDs deliverying up to 81 lumens per watt.
LED street lamps produce 80 lumens per watt while traditional street lamps produce only 58 lumens per watt.
State-of-the-art LED light scourse deliver over 130 lumens per watt.
This generates between 35 and 80 lumens per watt, depending on the actual LED.
Currently, the best plasmaTVs are capable of 2 to 2.5 lumens per watt.
LED offers around 100+ Lumens per watt and shed the light on the ground instead of spreading it all over.
They are also more efficient,averaging between 90 and 95 lumens per watt.
They produce more lumens per watt than the incandescent and can thusly produce more light with less energy consumption.
According to Tool Based Services,LEDs produce a generous 20 lumens per watt of power drawn.
LEDs provide around 100+ Lumens per Watt and put the light on the ground instead of wasting light pushing it in all directions.
This means these chips can produce between 50 and 100 lumens per watt depending on the particular chip.
The Illuminating Engineering Society of North America(IESNA) in 2008 published a documentary standard LM-79, which describes the methods for testing solid-state lighting products for their light output(lumens),efficacy(lumens per watt) and chromaticity.
For example, an EvoLux LED produces 76.9 lumens per watt compared to an incandescent bulb's 17 lumens per watt.
In 2002, Lumileds made 5-watt LEDs available with efficacy of 18-22 lumens per watt(lm/W).
However, it can be said of COB chips that the ratio of lumens per watt is very high, typically 80 lumens per watt minimum to well over 1oo lumen per watt.
In 2002, Lumileds made five-watt LEDs available with a luminous efficacy of 18-22 lumens per watt(lm/W).
LEDs of a certain color with a gigantic luminous efficacy of 250 lumens per watt are already being developed under laboratory conditions.
In the course of recent years, the white LEDs' luminousefficacy has increased to a startling 130 lumens per watt and more.
The typical incandescentbulb is rated at approximately 15 lumens per watt and the higher efficiency halogen bulbs can only achieve at best approximately 25 lumens per watt. .
The DIF 100 V4 Multichip has been in development for over threeyears during this time we have improved the spectrum, lumens per watt, and LED color ratio.
This is far in excess of the light produced by incandescent bulbs(15 lumens per watt) or fluorescent tubes(80-95 Lumens per watt).
LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent lamps, and significantly more efficient than most fluorescent lamps,with some chips able to emit more than 300 lumens per watt(as claimed by Cree and some other LED manufacturers).
If you consider florescent tube or CFLs,they provide 60 lumens per watt, but in all directions.
The problem with common UV/violet diodes is that theyprovide only approximately 0.5 to 4 lumens per watt, which appears darker to the human eye's receptors.
Companies like Panasonic, Hitachi andPioneer have banded together to create a display capable of 5 lumens per watt, double what's currently available on the market.
