luminous efficiency of the LED

This 300-Watt LED flood light fixture is nearly omni-directional beaming an exceptional daylight white light to essential exterior areas where lighting is necessary. Not only will you save up to 50 percent more in energy costs when compared to a 1000-Watt metal halide, you can rest assured that this LED fixture provides desired security.

What is lumen?

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a “luminosity function”) of the human eye’s sensitivity to various wavelengths. Lumens are related to lux in that one lux is one lumen per square meter.
