I have 3 - T10's with RHP's and the shelf - also had a 10mm channel routed for LED's I got on Amazon, and to be honest, I NEVER turn them on. I also did not have a channel routed in the 4th I ordered. Between the shelf and RHP the light really didn't "light up the enclosure" how I expected. I use a LED headlamp when cleaning as I have a window in the room and the natural light, of course NOT direct sunlight, that hits them seems to be working just fine.
