Ditch or fix my ATI power module

I have the original version of the ATI power module ($ T%'s and 3 LED) over a 120 with mostly softies and LPS. The earthquake we had a while ago fried two of the 3 LED modules. The 4 T-5s still operate. It's going to cost about $600 to repair the light. I imagine things have advanced quite a bit in lighting since I bought this unit. Is it worth repairing this or is there another retro and "upgrade" that makes more sense? I've been out of the scene for a while.

$600 from ATI? I would bet you can get generic drivers for a fraction of that amount.

I would run with the t-5's & see how things work out.

Hm, it is the actual LED module I think. Whatever the circuit board on the top of the light is for the LED clusters. Is that the driver? Seems like something generic might not play with the LED power module control unit. Yes, they want $300 each. Might be slightly less now since it is the old fixture.

I am not sure which one you have. I had always understood that the strength of ATI was in the reflector and bulb itself. I would think anything could drive that.

You'll be fine running the T5s alone. Also, for $600, you could possibly find a better LED supplementation rig than the ATI LEDs. Depending on how your lights are hung, you could possibly add a couple of Kessils to supplement color and spot intensity. I ran a Kessil/T5 combo in the past and it looked great.

That said, I switched from a 24 inch, 6 bulb ATI fixture for a Radion XR15 over my 60 cube a few months back. I'm very happy with the change. Almost all of the disco ball effect is gone with their new LED arrangement. You have to look for it to see it, and it's still pretty subtile. The software allows you to tune the color to whatever spectrum you want. It's really easy to keep it from getting too blue while still getting good florescence. They're not cheap lights, but you won't have to replace bulbs again.
If you decided to go this route, give the BRS videos a watch. They have some good recommendations for when you should buy the XR30 vs the XR15 for a given tank length.

You could also work in a DIY rig. My ATI light had a single row of LEDs screwed to each side. The guy that made it just used a heatsink that was about an inch wide. He mounted the chips to it without lenses and the spread was great for adding color to the tank.
