ya ive had a couple of em, i thought they were mostly about LED questions tho.Midnighttoker, 150 watts, not 1500.
This is the second thread Ive seen by you schotzky asking roughly the same question. It seems like you got mostly the same answers that you did before, 150 watt HPS will run hot, and in a small space the only concern will be temperature control. If it will be in a cold garage you will be fine as long as you keep ventilated.
