also one more point.hey guys
wanted to know what everyone's thoughts are right now on the most Efficient LED available today.
I want to replace several Gavita DE 1000W in our rooms we have 6 per room, we would like to replace and can't seem to decide what is a Suitable alternative.
any suggestions or input would be greatly appreciated.
just about every single cob fixture out there would beat the HPS watt per watt.
however unlike hps, the softer you run an LED the more efficient it is. cob "efficiency sluts" like to run their chips as low as 10-25W each to maximize efficiency at great capital cost
so lets take a $40 cree chip:
you can run it at 100W ($0.40/watt) and match an HPS easily
you can run it at 50W($0.80/W) and increase youre efficiency by ~10-15% over the case above, doubling your chip cost in the process
you can run it at 25W ($1.60/W) and increase your efficiency by another 10% over the 50W setup, again doubling your chip cost
so "the most efficient LED" is by definition "the most expensive LED". as far as chips by various manufacturers their top lines are all within +/-10% on lumens/W at a given wattage, but their pricing may vary by as much as +/- 40%. so most efficient shouldnt be your goal. most economical at a given efficiency should be your goal
