Halide to LED conversion

[mfrei64]

Considering the switch, but can't get any good info on what I need. Currently running 4x 400 W (2 10k and 2 20k)

Is there a formula for Halide wattage vs Led wattage?

I don't think you can do it that way. I have two tanks that converted to LED and the PAR on the LED full on exceeded the PAR on the MH. I had to start my LED at reduced power to keep from burning corals.
