  • it states that a 250W MH lamp has an “active” power of 285W. The term is “reactive” power because an electromagnetically ballasted lamps power factor is not unity (its power factor can be >0.95% if electronically ballasted.) So the reactive power consumed by the lamp and its magnetic ballast would be around 285W with a power factor of @87%. The reference to rectifier power I presume is the photocell / contactor module, so that’s valid to sum for a total power of 308W when the lamp is lit.

    However, that is the total power = 308W, there is no further doubling to 616W. That number has no basis and implies that LED lighting is grossly more efficient than other lighting sources (which it isn’t, that’s why they need heatsinks.)
