it shouldn't be too bright. heck, the 150W may not be bright enough imo.
70W is on the low side for 24. i'd go at least 150W with act supps.
the issue you're going to deal with is heat though (for mh mods). for the mods i've seen, a lot of consideration/thought was put into the venting. i've seen double fans and directional venting or manifold-style even.
the aesthetic issue will just be the bulb coloration. i bounced between 10000K, 14000K and now 20000K. it's not as realistic as i'd light but it shows off the tank nicely. 10000K's were too yellow (ushio's). hth
