Got a t5 grow light trying to figure out the real wattage there’s 4 bubs and they 53 watts each how do I find the real wattage. It’s says vegg light from amazon
@Lostscuba you’ll have to order a killawat meter for the most accurate answer. You’ll lose a little bit of energy in the conversion in the ballast.

That little computer that has red and black pointed things like a battery tester?the bulbs Are 53 wAtts
T5 and t5ho lights are pretty accurate on the listed wattage…
Mine are t5ho four bulb , four foot long fixtures and each bulb pulls 54 watts , so the whole fixture pulls 216 watts…
