Well if so you might want to tap the brakes and take a closer look at the numbers and see what they mean before you shell 5 to 10 times more money for them over CFL and Florescent tubes. With all lighting the two numbers to look at are Lumens per Watt (L/W), view angle, and to a lesser degree light color temperature.

Lumens/Watt is the measure of the efficiency of a light and is really easy to grasp. It tells you how much light the luminaire produces for each watt of power being consumed. The higher the Limens per watt the better. For example 100 L/Watt is twice as efficient as 50 L/Watt. It is a 100% difference. The Lumens measurement is made at 1 meter from the light source in the middle of the view angle if less than 360 degrees. If view angle is 360 degrees the light is measured at 1 meter distance in any direction around the circumference of the source.

Next is view angle. All incandescent, CFL, and fluorescent tubes emit light 360 degrees around the circumference of the fixture, while all flood lights have a view angle or beam width where 140 degrees is typical. This becomes very important as you start to compare light sources which I will now demonstrate.

[FONT="][B]Ok one of the most efficient LED lights for sale today is PAR38 42 White SMD LED Flood Light Bulb, 1314WH-CV. The Specs are: Lumens = 650, Power = 9.5 watts, View Angle = 140 degrees. Just from the numbers we can ascertain the efficiency is 650 Lumens / 9.5 watts = 66 L/W. Sounds great huh as an old tungsten incandescent is only around 18 L/W. But wait a minute the view angle is 140 degrees, not 360 of an incandescent bulb. Factor out view angle and you end up with [140/360] x 66 L/W and you get roughly 26 L/W which is still better than an incandescent right. Problem is we are not comparing apples to apples as we would not use incandescent for a flood light. Assuming we are looking for a similar light color we would probable use Quartz Halogen which has an efficiency of 22 to 26 L/w or roughly the same efficiency as a LED flood light? Interesting huh?[/B][/FONT][FONT="][B]
