There seems to be some interest in LED lighting. I love LED lighting everywhere, and here is why.
10 years ago we did a major remodel on a house just before we moved in. All new electrical, plumbing, HVAC, etc, etc. One thing we were after was energy efficiency and LED lighting had the "promise" of doing that. But, in the last 10 years, there have been major changes and improvements in LED lighting, and I have learned a lot and hope someone can find it useful.
We have several different kinds of LED lights, and all will work for a long, long, time, if you make the right choices, and have some luck.
Here is a pic of several of the kinds we have. Not shown are outside LED lights with integral and screw-in LED lights.
Here is what I found.
1. For the LED 4 foot shop lights, I started out with regular builder grade florescent fixtures and tubes. They are on at least 8 hours every day. After about 3 years, some of the florescent tubes started to get dim and flicker. I replaced ALL the tubes with inexpensive LED tubes with built in electronics (at each end) that were made to be a drop-in replacement for the florescent T8 and T12 tubes. And they have all worked flawlessly. That is 20 LED tubes, 8 hours a day, for 6 years, and not a sign of any of them giving up.
BIG THUMBS UP.

2. The nice flat panels, 4 foot and 2 foot long, are surface mount and about 3/4"thick. They were expensive, but are attractive, put out lumens equivalent to florescent tubes, but the the light is a bright glow rather than a harsh tube light. They are for kitchen and utility areas, but are too expensive for the shop. I have 5 of those (3-4 foot and 2-2foot) and they have all done well in the past 10 years. However, one of the 2 foot ones that is used about 4 hours a day is starting to give a short flicker about once a week. But still, a
BIG THUMBS UP.

3. Next is the 4" standard can lights with the trim that has integral LED lights and power supply. Some of these held up 2 years, and some are still going. The drivers/power supplies held up ok, but the LED elements burned out. I found some replacement LED elements and soldered them in, and they worked, but it was a pain. Finally what I did was find a decent screw-in LED flood light of the right size and lumens. I have about 20 of these throughout the house and have replaced almost all the integral LEDs with standard LED screw in light bulbs. Originally, these got a
THUMBS DOWN, but they are working ok now, but No 4 is MUCH better.

4. These are 4" recessed integral LED lights that are only 1" thick, and fit into a hole like a can light, but have 2 easy spring clips that hold them into the ceiling. There is a small 3"x3"x1" junction box that fits up into the ceiling so they are perfect for new or remodeling, are inexpensive, and are rated for insulation contact. I love these lights! They have been installed for 6 years and are flawless. A
BIG THUMBS UP!

5. Surface mount 6" diameter round integral LED lights. These are perfect for closets because by code you can't have ceiling fixtures or incandescents in closets. These mount on the upper part of the front wall in the closet right onto a round junction box. Installation is as easy as it can be. I have 3 in closets and one on the ceiling over a sink. A
BIG THUMBS UP.

6. General comment. Fixtures with integral LED elements that cannot be replaced. Don't buy cheap ones, and if you do, have a "Plan B" on how you will replace the fixture in the future.
7. General comment. Screw in LED bulbs. These have all gotten much better. CREE was one of the first to make quality reliable LED bulbs, but now there are other brands almost as good. In general, I would recommend fixtures that use screw-in LED bulbs for ease of maintenance.
8. Outdoor lighting. Most outdoor lighting has integral LEDs or screw-in bulbs. If they are integral, have a plan B to replace them if needed.
I hope this might help someone.
