Re: Heat of Metal Halides



Scott Corbeil asked about the heat of Metal Halide lights.
1) the heat thrown by X watts of MH light is the same as the heat
from X watts of FL lights. But you can easily have more watts of MH :)

2) 150 gallon tank wants 250+ watts of lighting. That's enough
to warm the room in temperate climate and in hot weather, it 
means you wish for A/C or leave the windows open. Think of it as
leaving the kitchen and bedroom lights on all day...
