I have a AI hydra 32hd light i turned up whites all way by accident in demo mode adjusting light spectrum (i honestly dont know why it allows you to swipe past 100 percent but it does) so the white leds stopped working i assuming they blew. Everything else and all led colors work as should so im going to offer light up for trade for coral. This would be good for someone who keep blue spectrum or someone looking to add more blue seeing white dont work. But the new pucks can be bought from Aqua illuminations for 160 for 2 pucks and shipping. There very easy to install and i already reached out to them and was able to get a invoice to order them if noone wants to trade.
