^^??? A 1000w halide would cook a 40b, 75,000 lumens at 100%
Metal halides should produce around 75 lumens per watt, LEDs are supposed to be higher but I've seen reports that most fixtures you'll end up about the same as halides. So a 75w halide would be a little under a 150 would be way over. or 120w led fixture should be good as well provided it is dimmable. T5s you'd need at least an 8 bulb unit, but it depends on the bulb. Look up luminous efficiency and it will give you a good idea of lumens per watt on most lighting types
