a 1000w HPS runs at an average of 100,000 lumens- 150,000 lumens
you do the math
LED's everage lumens
Red LEDs - 42 lumens/watt by Lumileds, 28 by ETG, 22-28 by Avago.
Red-Orange LEDs - 53 lumens/watt by Lumileds, 21-22 maybe now 28.5 by Avago, 15 by Toshiba.
Truly Orange LEDs - 18-22 lumens/watt by Toshiba, 18-21 lumens/watt by Avago.
Yellow and "amber" LEDs - 34-35 lumens/watt by Lumileds, 14-16 lumens/watt by Toshiba.
Yellow-Green LEDs - 8 lumens per watt by P. Tec Opto, 3-4 lumens/watt by Toshiba, but there is a way to get 20-40.
Green LEDs - 25-32+ sometimes 42 lumens/watt by Nichia, already 33 and soon 65-70 by Cree, 46 by Lumileds, 16-plus probably 20-plus by Toyoda Gosei and Avago.
Nichia green LEDs get 30-55 lumens/watt at 5 milliamps
Blue-Green LEDs - 25-28 lumens/watt by Nichia, 37 by Lumileds, soon maybe 41-46 by Cree.
Blue LEDs - 9 to optimistically 12 and soon 20.6 MAYBE 23 lumens/watt by Cree, 7.5-8 to rarely 10 lumens/watt by Nichia, 13 by Lumileds, 5.5-plus by Toyoda Gosei, maybe Avago - UPDATE 11/4/2004.
White LEDs - 64-plus by Citizen Electronics, as high as 50 lumens/watt by Nichia, 37 soon 50 by Lumileds, 23-plus by Osram, now as high as 47-69 for ones with new Cree chips - updated 10/9/2006.
