No mystery Watts are not . KilloWattsperHour (kWh). The two are entirely different. 200 watts is 200 watts. However, 200 watts being driven at 1400mA cost more after 12 hours than 200 watts being driven at 1050mA, by a 25% savings alone. So after 12 hours of running a meanwell HLG-185H-C1400B driver will cost based on amps being drawn.
HLG-185H-C1400B HLG-185H-C1050B
1.4A x 12 = 16.8kWh 1.05 x 12 = 12.6 kWh
1 month 30 x 16.8 kWh = 504 kWh 30 x 12.6 kWh = 378 kWh
12 months 12 x 504kWh = 6048 kWh 12 x 378 kWh = 4536 kWh
cost per kWh $ 0.16 $967.68 $ 725.76
average cost savings is $241.92
not calculated is cost of cooling.
Higher voltage has less drop over distance.
I think where everyone is confused is the 200w part. Maybe it should be said that the cobs produce less light at 200w?
The part were having trouble with is this 25% savings in electricity costs simply from switching 1 200w light to another 200w light.
