It's time to contribute to the community by sharing your experiences. First review, please keep it simple. Very happy with these lights: bright, uniform, stylish, low power consumption and easy to install. When I started the project, I considered traditional recessed can lighting, but encountered problems with ceiling joists. With these fixings you don't have to worry about the position of the ceiling joists. Plus they save money. They average $15 each, better than what you can make with cans. Suggested improvements: 1) The power supply must have cable clamps. With no clamps, Romex simply hangs on wire nuts. 2) The lights are attached to the plasterboard ceiling with spring clips. They are strong and secure, but if you decide to remove and reinstall the fastener you may damage the edge of the drywall. There must be a better solution. I would like to share my experiences here and hope that other artists can benefit from my knowledge: - Color choice: I understand that the color depends on personal preference. At first I got warm white (3000k) but didn't like the yellow (even for a family room). Cool white (4000k) seems like the best choice to me. I have a dining room 12x13, I installed 6 lamps around the perimeter. The original chandelier is in the center. 6 Torchstar made the room really light and inviting. But when I turn on the chandelier with 6 warm white LED candelabra, the room seems to be on fire. It was a pleasant surprise.- Design layout before cutting holes: First design and attach (with a pin) to the ceiling. I've found that 24 inches from the wall seems like a good distance. The distance between lights can be 6 feet or more depending on the number of lights you plan to install. Either way, what you need is a designed template, not just random stuff. I've seen newly renovated homes with erratic recessed light patterns and they look bad. - Installation: Buy a 6" hole saw (6-3/8"). Lowes for $20 but I'm sure others will work just as well. Use a cordless drill and set it to one of the clutch settings, not the drill setting. The saw is large and can bind, and when it does it will either mess up the ceiling board or twist your arm if mounted on a drill press. The hook setting saves you a lot of hassle from thin board through the hole first. The board keeps the saw centered while cutting. Otherwise the saw will go everywhere, ruining the ceiling - Get dimmers: You definitely need dimmers for lighting. I used Leviton Decora dimmer switches because they matched my existing Decora style switches. But all LED dimmers work.
