I have two 4' T5 fixtures on my tank with "Blue" bulbs. It gives the nice dawn dusk look. They are sunlight supply. In theory they don't have water proof plugs/end caps and I've heard of people getting shocked easily from them, although I haven't had any problems.
MH DIY Reflectors are fairly easy to make and DIY T5 reflectors can be done as well, although they are a bit harder.

the reflectors in hydroponics can be just as good as the ones for tanks, hydro guys are just as worried about efficiency as we are, its just they have alot more cheap low quality ones than we do for aquariums.
you get what you pay for no matter where you shop but hydro guys dont pay the excess premium that we aquariests pay for our specialty equipment. You can save a bit of money buying a hydro one that is still good quality (dont buy a $20 reflector and expect it to work as good as a $300 one) but they have a larger market where people usually buy multiple units, so the costs go down due to volume. Best way is to get some high reflective aluminum and make your own, you can buy a sheet of polished aluminum for fairly cheap and slam a reflector together and copy whatever design works best for you, or do what i did and buy a cheaper hydro reflector and modifiy it to fit and preform better on a tank shape.
