Comparing LED downlights in kitchen
I posted recently about my attempt to replace the 4" soffit downlights in my kitchen with CREE LR4's that turned out actually be 5". I've since picked up two LED screw-in bulb replacements and a Sylvania RT4. I took pictures of each and posted my thoughts at the link below. Included is a video showing the turn-on delay of the RT4s.
