I just hook up mh hortilux blue and my room is running 2-3 hotter than it did with the hps is this normal or is it seasonal change?
Agreed!Yes, they run a little hotter than an equivalent wattage hps bulb.
That would be true if they were equally efficient, which they are not. MH is about a third less efficient at producing light than a HPS. If it isn't producing light, its producing heat.That makes sense due to the fact that an HPS puts out quite a bit more light, therefore more heat.
