Hi YL - nice to see you here. How did you get on with the toms?
Hi Nova head.
The two cfls are higher than the fluorescent fitting (shop light) due to how hot they get. In the picture the shop light has swung over towards the back as the lid of my box when closed holds it central. The shop light is only 36w total and I added the 2 20w cfls to push that up to 76w. They are where they are as I couldn't see a better way to fix them but so they can be adjusted. If you look at the tubes they are spreading 18w across the whole length and are nowhere near as bright as the confined 20w lights.
Remember, this is all in a small confined space.
