I've played around with tec peltiers, they can get really cold especially if you stack em but not very efficient. The hot side gets really fucking hot Might be good for a diy dwc chiller or dehumidifier. I have everything to build a water cooled cob light, I will be using vero 29 SE , cmu 2287, and cxb3590 cobs with copper tubing coils for cooling, I also have a cpu radiator and a bunch of reds to add. Should be fun.
