How long is the tank? If we're talking 24-30" long and shallow like that, you should be fine keeping just about everything... Assuming each lamp has an individual reflector...
Rics don't like getting SLAMMED by light, so halides can be bad for them if they're placed wrong in the aquarium. I grow mine under halides, but they're a decent ways away from the bulb where the PAR isn't as high...
apparently you can get them used to MH but it takes alot of time and effort. im just gonna go with t5's, i like them because with 6 bulbs i can make the colour however i want
