It's probably a good idea to keep extra lights on hand these days...

I have 2 - 4 foot ATI hybrid units over my tank and it looks like one will be going back for warranty.




One of the LED unit reflectors has burned up and the 2 back bulbs will no longer light up. They just flicker. The LED's themselves still work fine.
I sent an email off to ATI and am waiting to hear back.
I'll resurrect one of my old 400W MH in it's place while it's gone.
