The thing about Feit is that they throw their brand on a lot of stuff. Kind of like Craftsman name on Dewalt, Black & Decker, Porter Cable tools.
Some look cheap, some look nice. I used some supposedly 23 watt Feit baffles, and they were the same exact trim as ones offered by Luminus, Bioluz, Sunco, and a few others. Almost all the others listed them at 19 watts. There was no difference in color or brightness. I bought some of each brand to compare them.
Another type of Feit was purchased by a customer, he got them at Costco for about $14 each. They said 22.5 watts, and looked really close to one offered by Philips. They were nice and bright. He took my suggestion and bought extras.
I've used the ones offered by Sylvania, they were $20 each at a local store. Great lights. Utilitech from Lowes is made by Cooper, a very trusted brand, great lights. I'm not sure who makes the Commercial Electric, but they work really well, and they have different wattages which match. TCP is a great brand too for about $25 each
As far as buying online....
A supply house/store sells with a markup that includes honoring returns on defective items. Take one that costs $15 + tax, it's about $17.00 total.
If I buy it for $12.00 with no tax or shipping, I've got margin. Now, instead of driving out to diagnose, then taking one to a store to return it, then go back and put it in, how much time did it take?
Or I could go to my basement and get one or two of that kind, take them with me, and I'm done in 15 minutes.
I'm already on the hook to make the diagnostic trip, and it's fully expected that I warranty what I supply, I may as well buy cheap and get paid to warranty it.
I use enough of them that I have them on hand. I typically keep 100-200 of them, various wattages and styles.
But I can say honestly, that out of the past 3 years, I have had one defective right out of the box, and have warranted zero.
