I upgraded our pool light to LED 4 years ago and we decided to go with the Pentair Intellibrite 5G. Unfortunately, it stopped working a couple of weeks ago.

Is there a repair kit available for a driver replacement, or would I need to replace the whole light fixture?

If it can't be repaired, is there a more reliable model to go with? I'm not too happy with only getting 4 years out of an $800 light (which is now $1200).
