So that's not watts drawn from the wall, the ac side? It's the watts on the dc side?No, I think that is correct. You have selected results for 6 leds. It is telling you the
total watts dissipated for the 6 leds at 2.0 amps. Watts=voltsxamps
Thank you!Correct would not include driver losses or any thing else ie fans etc
I downloaded the data sheet but didn't know that was there. Thanks for that!Check the data sheet of the driver you intend to use. The better quality Mean Wells will have a graph showing efficiency vs load.
I missed that part about 6. Then it is totally correct. String of 6 would be that many colts and that many watts.Even on 6 cob's? Or did I misunderstand what LED multiple means?
Yup! Saw that. It seems that once you're around 85% of driver capacity, with the 240 series anyway, the efficiency is minimally affected if at all. That answers a lot of questions for me and effects my build approach.I missed that part about 6. Then it is totally correct. String of 6 would be that many colts and that many watts.
The more "full" a driver is the more efficient it runs. It's in the data sheet for all drivers...usually called efficiency vs load.
DC output amps x voltage to gets you the wattage of the load(your cobs power)Is there a formula to determine the watts drawn from the wall? I'm sure this is partially on the driver data sheet and cob spec sheet?
not really kinda sorta ... the 120 is ~150 watts, the 185 is ~200 watts, and the 240 I believe is ~250 watts .What effect do the different driver series have on output?
For instance, what's the difference between the 120, 185 and 240? I understand that these numbers represent the wattage of the driver but how does that affect the output?
Correct. The wattage, I think, probably represents a "mean" throughout the series.not really kinda sorta ... the 120 is ~150 watts, the 185 is ~200 watts, and the 240 I believe is ~250 watts .
