Metal Halides

jediraverz · 05-15-2008, 08:29 PM

So I finally got my tank up and running and Ive had my Halides running since 2pm its now 530 and the top of my canopy is scortching hot. Its hot enough that i cant keep my hand on it for more than a couple seconds.

I retrofit a single DE bulb and its the reflector mounted to a piece of metal and then to the canopy. i just put a piece of glass over it so that i dont sun burn anything and now its sending all the heat up towards the canopy. Is this safe? how do you normally retro fit a Halide bulb to your canopy?

doesn't sound safe to me. Is the canopy made of wood?

Not very good at retro kits but I would looks for a way to connect major fans to it.

yes the canopy is wood, currently I only have 1 fan pushing air in i figured it would get pushe out the back. I ran it before for a few hours without the glas piece and it stayed cool, but I have to have it over te bulb

I would try to get fans blowing out of the canopy, and make sure you don't leave them on when you aren't home, or are sleeping.

I think I might have to sell this unit and settle with some good PC's or T5's. My chiller is creating a ton of heat along with the halide bulb and balast my tank is still at 82 degrees... good thing Im testing everything out for a while to find out what works. Any suggestions?

open top!!! good in more ways than just heat

What you need to do is close the back up. One fan in a canopy is fine. Fan blowing out one side and a hole on the opposite side will cause a tunnel keeping the canopy cool.

Did you leave an air gap between the wood on the canopy top and the reflector? If there is no air gap, you are transfering the heat directly onto the wood from the reflector, in essence, creating a fire hazard.. The screws that hold the reflector to the wood, need to be removed, and you could use a few washers or a small piece of pipe for your spacer. Get that metal reflector off of the wood, then think about fans to pull away the heat.

Thanks guys..im gonna try the spacers... though it may keep the canopy from getting hotter , Its hard enought to keep this room cool, with all this stuff I think the summer might be tough

jediraverz · 05-16-2008, 12:13 PM

okay so I did the spacers and its about a half inch away from the canopy. The lights turns on in about 45 min im gonna let them run for a couple hours and ill let you guys know if it helped. I might also add another fan to the canopy but we'll see how this turns out... I dont want to loose my halide its too beautiful!

im running one 250 watt pendant on my 65g and it stay pretty cool because its open top. Im running two fans in through the canopy and slot on the oposite end. Tank stays at 79. Still high but in the safe range.
