So when you look at the power consumption that is supposedly 600 watts, the actual power consumption is about 115±5, roughly 115/120 watts. So you need to multiply the watts of your LED panel by about 2. So roughly 250 watts max, it seems. A ViparSpectra R900 of 900 watts consumes 425 watts, and a 160-watt one consumes 100 watts, just for info. For example. So the "lowcast" panels, watch out for false information! Look at the watts consumed to realize it, not the so-called 600 watts. I've seen 45-watt panels measuring 30 cm by cm sold as 1000 watts. They add up the number of 10-watt LEDs and give you a false result because the 10 watts and other LEDs don't run at 100% of their capacity, otherwise they wouldn't last! Be careful.
