why hang lights or buy a fixture when you are building a canopy? You will pay half the cost of a fixture using a retro set up (of equivalent peformance and with individual reflectors) which just needs to be bolted to the canopy and sometimes wired. If he can build a canopy that will be childs play putting in.
You can find sunlight supply's two bulb 36" retro kits for around $100 each with bulbs. they arent the pinnacle of T5 development but they are still a good kit and use Fulham workhorse ballast. four kits (8 36" bulbs, 312 watts) will cost about $400 and is plenty for a 125 gallon. You may be able to get the nova fixtures for the same price but the lack of individual reflectors is a major detractor.
you can go with a catalina aquariums 72" retro fixture which has eight 80w bulbs (640w), individual reflectors and also uses Workhorse ballast for $500. the bulbs might not be the best in the business its still a good set up for the money and far superior in watts and reflector to the nova
coralvue (dont actually know how good they are but based on the MH kits and support if you buy em from the right place I wouldn't hesitate to try em) These are simular to the sunlight supply "ready fit kit" which are just like the sunlight retro kits described above except the ballast is self contained in the retro fixture and no wiring is required (catalina kit is the same way). four screws and a plug is all it takes to install. $120 each for two 36" 39w bulbs ($480 total). the only reason to consider these over the sunlight retro's are ease of install due to the lack of basic wiring. Or you could get proven sunlight supply ready fit 36" kit itself which are another $15 more ($540 for kit)
sunlight supply ready fit kits
coralvue's knock off $15 less per kit
just a few suggestions. you can look into Aquactinics and Ice cap kits as well but they probably wont end up being in your $600 budget given the amount of bulbs your probably want to keep everything.
