Thanks for the input Krogith...

That reflective material is Mylar... not aluminum foil. I'm not worring much about hotspots created by Mylar... if any.

Here's the clear response on why Mylar is a better option than white paint:

One standard HPS bulb puts out 140,000 Lumens. If White paint reflects 86% light you only end up with 120,400 lumens reflected. Sidelight is as important as top light but all to much people forget it all together. You lose 19,600 lumens that is absorbed by the paint.

With Mylar you reflect back 98% of the light that hits it. So the same 140,000 lumens HPS light as before you only lose 2800 lumens so you get 137,200 lumens reflecting back. That’s like adding a 150w HPS light for free. If you have more lights like I do then it ads up even more. With 6 1000 watt HPS light and Mylar you get another 100,800 lumens of light just for using Mylar. That’s like the 7th light of 1000 watts is free.

That’s why you should use Mylar It’s all in the math.
As to the clear tubbing: Yes, you're right. I know. I covered it with aluminum foil (wow! Is this the foil you're reffering to?) to keep the light out. I'll try and get the the black tubing for the future...

Thanks for the props on the cabinet Krogith... thanks for posting.

Best to you,
