Not trying to pimp anyone's blog but the Grow Cheaply guy has a little free course and one video on Environment is good.
His point is that the environment mainly temp, humidity and temp of the plants tops is more important than lights or fancy nutes. He is running a wall unit AC and sometimes runs CO2 but says it is not a big deal for CO2.
In the video he is using a cheap wing reflector with a 600 watt bulb (I think a decent bulb Ushino?) and a digital ballast. Cheap stuff. It is about a $179 light set up. He has the light on a light mover/light rail and he clipped a little fan that blows over the bulb. Simple stuff but clever. He said the light mover lets him reach more plants with one light and the plant tops cool off while the light is away from the plant.
He does it cheaply and gets good results.

This^^^^. Hps lamps rock...especially the newer double ended 600 watt ones for smaller spaces. You dont have to have 9 or 10 foot ceilings like the super hot 1000 watt de's. That being said...they still kick out heat (air cooled single ended lamps were popular a few years back for this very reason - but it was a trade off). Where hps lamps really shine (even the older single endeds - ) is when you use multiples of them (cross lighting) and mixing them with something else state of the art but in the blue spectrum for a better more potent end product. This is where the newer 315 watt lec lamps come into play. If circumstances dictate you can only have one doubel ended 600 watter for the smaller spaces everyone has....try like all hell to supplement that fixture with a 315 watt lec. Serious. Its like the perfect combination. And it will far surpass a single ended 1000 watt hps or mh in yield and quality. Only drawback is the heat the double ended kicks out. The 315 watt lec supplement lamp...not so much. But definitely....hps and lec lamps go together like peanut butter and jelly. The combined spectrum and intensity is about the best there is(practically and availability wise) right now.

For all the smaller growers and tent guys out there (just about everyone) that want super efficiency ant top quality...i suggest the Sun Systems Grow Beast fixture. Its a 40 inch wide behemoth...but on each end has a 315 lec lamp and in the middle a 600 watt double ended hps in a wide throw reflector. Just watch your heat for the small spaces. This lamp has it all. And if you really wanna set it off for an awesome small garden...throw it on a 6 foot light rail. I cant recommend this one fixture containing 3 lamps enough. Its perfect for all you personal use and tent growers. Its state of the art and has a total spectrum damn near exactly like the sun. Its a pricey lamp (actually not if you factor in buying the 3 lamps in seperate fixtures) but thats a one time buy in for something that will get the job done. And you wont have to buy new bulbs for these fixtures for at least a year..more likely two. I wish they had these when i had a much smaller operation years ago.

Its gonna get hotter than a sumbitch without a.c. but a 4x8 tent and the Grow Beast on a 6 ft ligjt rail would crush it. But a.c. is a must i would assume.
