it does but anything ati i find a bit high in price

MH/T5 combo all the way baby. I can't feature paying 5x as much for a fixture that is almost as good as MH.

Even if you have to buy a chiller you're still looking at a cheaper option than LED...

I still had to run my chiller even with LED, so no savings there

I've decided to continue with LEDs in my mp10 controllers as I can't find a small enough halide bulb to fit

That's probably 50% of the selling features for LED is that it runs so much cooler. If you have to buy a chiller anyway then what is the point?

Try touching the heatsink; I dare you

The thing is, both LEDs and MH "runs" hot but MH "dissipates" heat (and light) omnidirectionally (since its a round bulb) and cannot be fitted with heat sink to take away the heat. On the other hand, LEDs dissipates heat bidirectionally but emits light unidirectionally and so can be fitted with heat sink on the opposite side with heat sink to take away the heat. And hence the "runs cooler" market hype If some sort of technology comes which allows MH to be fitted with heat, that market tag line is going to be buried.

They are not hot at all. Even after running at 100% for hours. I have fixtures with built in fans and other ones without them.
