9. Pic11… basic layout…problems already arised… As you can see, two bulbs will not fit in there. At least not my two bulbs. I have one 600W HPS and a 400W MH. The spaces that are between the couplers and the Bake-A-Round will get a piece of PVC pipe in between. In this picture you can see that I tried to place the bulbs in a happy-medium. There are parts of the bulb that will be out of the cool tube, but those parts don’t product light. The actual parts inside the bulb that emitt light, those have glass around them. Wouldn’t make sense to cover your lumens, would it?

10. Pic12… Almost finished cool tube. As you can see in here, I placed both bulbs. It’s not finished in this pic because I didn’t have aluminzed tape… so I had to wait till the next day to buy it (no 24hour hardware stores over here!). All you need to do now is seal up the Bake-A-Round unions with the PVC pipe with your aluminized tape. You can use S-hooks to hang the cool tube… you can see the holes drilled for that between the power cables.
