This always comes down to expectations. A 150 hps will flower the plant out and produce a better yield of more dense buds than a comparable wattage of fluorescents. I really see 400 watts as the ideal starter lamp. Not a lot of heat to deal with and the yield will be great for most personal smokers. A 400 watt lamp will last you a long time. Most people tend to buy a small 150 or 250 only to realize they wish they had bought at least a 400 pretty soon after.
I get about 1 1/2 to 3 oz per plant in soil under a 400, I also have a 4 bulb t8 fluoro setup (uses approx 144 watts) that I recently flowered some test plants under and yielded about 1/4 per plant. HPS should do better than that but still the results speak for themselves. 400 watt will do a 3ftX3ft space perfectly.
