Well I was thinking of switching to the T5's to even out the light distribution over the tank. With the MH pendents I have the middle gets less light. I also wanted to use less energy and reduce the amount of heat going into the tank.

Mike, I haven't ever actually used MH, but I do currently have an 8-bulb Tek unit over my 3-foot tank. I love it! I'm keeping soft corals, LPS, SPS, a Gigantea anemone and a clam...and all seem to be quite healthy and happy. You're free to come over and see if you want. I'm using a mixture of bulbs and really love the colours.

how many watts is a 8 tube tek in total, compared to your 500W now?
thats how much power it uses doesnt matter that its MH, incandescent or T5. 432 is a 8 bulb tek if i remember correctly, so thats not much savings in electrical energy, probably wont pay for the upgrade costs for at least a number of years. But i would go with what you want your tank to look like, i personaly love the shimmer for MH and would never go with anything else, I also like that there are darker parts to put lower light coral in to give more contrast in my tank. But it sounds like you want even consistant lighting, so go with the tek its your money spend it how you want

Have you considered putting a couple fans in the canopy?

Yeah I thought about that. I'm more interested in even light distribution and if I used a 6 bulb 54 watt T5 setup it might be worth it on power savings but maybe 6 bulbs wouldn't be enough.

i read a study somewhere and when they tested different mh lights and ballasts most used huge ammounts of energy when starting up and while running,electronic ballasts ran at proper levels but i dont think the starting up was any better,im thinking of buying a kill-a-watt so i can test things myself and know for shure instead of just guessing all the time.
i have no proof myself but i would shure assume any mh light system is gonna use a heck of alot more power than a t5 of similar wattage
