Hydra 52 Question

I just bought 3 Hydra 52's for my 220g tank. I have the AI Director for control. The modules themselves work great however the AC adaptor gets REALLY hot. After about an hour they are almost too hot to touch. All the fans are running on the light modules and they are perfectly cool to the touch. Every once an awhile they trip my GFI on the outlet as well. I am only running about 6 amps total on a 15 amp circuit so I know it isnt overloading and all my other AC adaptors are cool to the touch on other equipment plugged into the same outlet. I contacted AI about it and they said it is normal for them to run that hot up to 140 degres F and occasionally they have had reports of tripped GFI's. He said they are designed that way in regards to the heat but they couldnt control the GFI problem.


That seems really weird to me not to mention a huge waste of energy. I could see maybe warm to the touch but 140 degrees is a little nuts. I would have thought they would have designed that out given the price tag on these things. Anyone else running these lights with the adaptor that hot? Afraid of burning my house down with these things.

 

I am in a new construction house so that might explain the GFI situation. I had them running for a few hours last night and it didn't trip. Once I moved one of the 3 lights to a different outlet it seems to work better in regards to GFI tripping but the heat is still really bad. I am going to get an infrared temp sensor to see how bad they are getting. I agree on the energy waste too. I cant imagine I am getting the full value out of these with that kind of heat. Not what I would expect at $600 a pop. I like the idea of changing them out for a higher amp adaptor but worried that that might void my warranty if I am not using theirs. I'll ask them. Blackx if you could let me know if your Hydras are running that hot that would be appreciated. Maybe AI could give my hydra adaptors if they are compatible.

 

Ok. Something is wrong with mine then. I only have my blues on 100% and whites at about 30% right now to test them and after about an hour I cant hold onto them for more then 20 seconds or so. Also reading the back label of the power supply shows output of 36 volts and specs on the lights show 135w output which = 3.75 amps. The rating on the power supply is only 3.33 amps output. I always thought you were only supposed to run power supplies at about 75% or less of the designed output but I am not an electrician obviously so maybe I am wrong but seems odd. I think these power supplies are jacked. I have 2 MP60's running on this tank and I can barely tell they are hotter then room temp on the power supplies. Going to call AI on Monday and get a better explanation.
