Yes you are right. Those are good points.
I should have said I have an All-Glass 48 " full hood with the standard, single 48" bulb light fixture that comes with it.
I Emailed All-Glass my question but got no answer.

I was only asking about light fixtures. I have already researched the other factors.

That is well said. But I was only asking about a light fixture.

Fair enough, but the point ppl are trying to make here is that we didn't get that from your original question (I certainly didn't) - you asked if you could swap your fixture for one with more bulbs, but not why or how you would expect to benefit or what exactly your goal for doing so was. That's what all the clarification-questioning was about. It's sorted out now so all good. Good luck with your upgrade!

You can get 48 inch single, double and tripple bulb fixtures. The bulb holder (hood) will be the same length on all of these but wider.
My 75g tank came with a hood with a single bulb but I upgraded to a double bulb which made the hood wider. I wanted the tripple bulb but it made the hood too wide to easily open the glass tops.
Is this sort of what you were asking?

Well you know its the kelvins but the watts... the depth, now thats the kelvins thats what counts! depth, unless it looks dull in there, or if your plant dies, or if you want to spend $600 on t-5 lights.well if u do that you'll never lift your hood again either so then depth blue rays red rays well if you look at the bulbs color chart theres not much red not much blue well then pick one any one at all and stick it in there see how that one works and of your plant dies well move your tank directly under one huge chandellier and leave it there. HaHaHaHaHa help any? thats how a drunk salesman explained it to me and my husband, all we could do is listen!!!

There are a couple of factors you need to consider.
One is the width of the new light fixture. Will it fit in the area that the one bulb fixture occupied ?
The other is heat. If the material between the light and your water is plastic or Plexiglas you may have a problem. If you have glass between the light and your water you will be a lot better off. Also if the light is sitting flush on your "top" the heat may build up. It will be better if there is a little space between the light and the top so the heat can dissipate.
