Reflectors do reflect up to 30% more light than if not used. Also reflectors are good for protecting the flouressent bulbs and the plants they shine on from water run off from plants on the shelves above, and reflectors also help to channel any heat to the ends of the shelves.

Just to let everyone know, the link for this post has changed: I think you only need to use one plug at the outlet end. You can connect up several light fixtures one-to-the-other in a straight line using the direct connector that comes with each light fixture. If you have to angle to a corner cab, or insert lights into a cavity, you can still connect the lights to each other using their flexible connector. Call Pegasus Lighting Associates and they will help you if you give them your measurements. 1-800-392-4818.

That big blue sticker at the top is panel brand. It looks like an ITE. I don't think they make those any more. I can't tell from the picture if there are any empty slots. I looks like maybe not. If there are empty slots you should move this breaker to one of the empties. Plugging a new breaker into the burnt slot is only going to cause the breaker to burn up. If you must use this slot switch a circuit that has very light load to this position until you can replace the panel.

Thanks, lazy_gardens and kirkhall. The lights are all snugly installed. We did call Lutron and Cree after I posted this morning. (Thanks for the suggestion, laz_gardens.) According to Lutron, they test for compatibility, and unless they hear a significant hum or see flickering, they think that things are ok, and stated that LED's humming is a natural byproduct of the electricity cycling 120 times per second. DH didn't ask Cree about the humming (I'm not sure why...), but he did ask them about their chart, and they said that if we noticed flickering or humming, then decrease the number of lights on the circuit until we no longer notice those characteristics occurring. DH was more concerned about whether running 12 lights on the circuit could cause premature failure of the lights or the switches, which he was told is not a concern since the switches are labeled capable of handling 150w of LED lighting. Our 12 lights fall in that range. That's very interesting that some of your lights hummed and some didn't, Kirkhall. Are they the same brand we bought? DH can't hear the hum (he has some hearing loss and doesn't pick up on noises outside of his hearing range). I haven't climbed the ladder to check them up close. I could try that and see if I can figure out which ones are creating the sound. The noise is subtle, and when the household is active I don't pick up on it as much. The sound reminds me of the hum of fluorescent lights in a classroom.
