I chose these as they match the "old school" look of a fixture that is actually recessed into the ceiling. I like this for a room where I use screens because there is a further downward beam of light and should cause less glare. I replaced a couple of surface mount lights with 16 in a 20' x 20' room. In the brightest light, the room now shines like Monday Night Football. I would say it's at least 5 times brighter than before. But I've added a dimmer and am happy to report that they still look good at lower brightness levels. They dim steplessly without flickering. A note on dimmers: If you are buying 2 packs of 8 and installing 16 lamps controlled by a single switch: get the 250W version of the Lutron LED+ dimmer. 16 bulbs of 15W each is only 240W, so a standard 150W LED dimmer won't do. The Leviton I first tried with the backlight hummed loudly, but the 250w Lutron fixed the problem and the bulbs work great now. A normal dimmer costs about twice as much, but it's worth it. I only installed them a few days ago so I can't comment on their durability but so far I'm happy with them.
