I found my mogul sockets off 1000bulbs.com

I know that's probably not helpful for your case, just thought I'd share.

Thanks anyway I ended up just chopping off my current socket and got it out of weird casing. This turns out great it's a easy diy! Cost me under 20 bucks and looks just as good as a store bought one.

Just put a couple loops of copper pipe infront of your fan and run your water thru it. If you do that, you should make sure moisture doesn't damage your bulb.

Mystic,
I just used this to make a cool tube for my 600 watt. Thanks so much, it works great and I'm going to be making the reflector today to get that extra light back on the girls. This is going to be perfect for my next grow. Thanks a ton.

NewbieG:

What type of 600 watt bulb are you using, (MH or HPS & what brand), for sizing referance, (or better yet can you also take measurments of the bulb itself, Dia. & Length). Also if you have the ability, what kind of temperature is the exterior of the tube hitting after about a 1/2 hour runtime?

I am interested in connecting two of these in series with a 600 watt hps in each and hanging the pair vertically, (as in a vertical grow for flowering). Was wondering if the diameter of the Pyrex Bake-A-Round tubes can handle the heat from a dual setup as described?

duckfool:

Thank you VERY much for the informative instructions, parts list, photo's, etc... Good job!

I'm actually not using a bake around. I'm using a 10 inch candle hurricane shade, but I would realy suggest using a 14 inch one. The 10 inch one fits my 600 watt bulb after all was said and done but its just barely. I am probably loosing a few lumens. I was actually thinking of attaching two of them together so that I could have dual spectrum 400 watt and 600 watt bulbs, but you are going to have to attach the two glass shades and are going to have to cover a good part of it with tape to make it work. Maybe thats where your second light could start. Here a link of a hurricane shade I would suggest. I have no relation with them, just really cheap stuff.

change the xx to tt. They also have the 10 inch shade I used if you want a straight cooltube.

Yup got it off Ebay for $28 with shipping. Search for "pyrex bake tube" there's tons.

I found on another site, (don't recall which right now), where a member is using this setip with a 1000 watt hps, he writes that it fits and has no temp problems whatsoever.

So I took some temps of my cool tube running a 600 watt hps (95,000 lumens) and got 106F exiting tube and 126F 8" below tube. The tube and all asociated parts were cool enough to handle with bare hands. I see no problem running this 24/7. Also this was only hooked to 4" ducting and a 4" inline fan, not some giant air sucker, so temps could probably be a lot lower depending on fan type!
