I don't want to come off as a QB shill, it's just what I use because of performance, cost to run, and low heat. Everything you've seen me post has been grown under 260W QB. Here is a bank of QBs in my flower room.

They produce some nice buds, these are between 1-1.5 ft main colas.

They will penetrate into the canopy, here are some plants just before chop after removing the leaves to show the lowers.

Here is one 260W in a 3x3 tent, and 2-260W in a 4x4 tent. These are multiple strains, so monocrops with better canopy management would allow closer light placement and better yield.

I have a 130W QB in a 3x2 tent that I use for making seeds. The bud size is not impressive by any means, but they are fully pollinated, so they pretty much stop putting on mass at the time of pollination. All things considered, buds are full of seed and the light is great for the space/purpose.(the dead leaves at the base of the plants have since been cleaned up

Again, I'm not trying to sell you on the QB's, just trying to give you more options. Your heat worries with the HID can be a major factor that these QBs can mitigate. You might be able to get away with a smaller portable AC unit that vents out of a window. I have not used CMH lights, but have seen them in setups at the hydro shop and they can throw some heat.
I run a staggered perpetual system, so electrical cost savings and the time to clean hoods, replace bulbs was a significant part of my lighting choice calculus. The humidity and heat of my growing climate forces me to stay on the LED side of lighting. DE HPS would probably grow thicker colas, but anything much bigger than I'm getting will have a serious mold risk, so just keep in mind all of your environmental limitations/factors when making a decision.
