I've decided to install recessed lights into my guest's bedroom, which only had a single light fixtures in the middle which wasn't providing adequate light anymore because I'm using that room as my office now. I've added 5 recessed light and i thought these ultra-thin recessed lights are much easier to retrofit than the one with the traditional housing. First, it's much simpler to have this installed and run the wires, and also cheaper because i don't need to spend for 5 additional recessed housing, which usually cost around $15/each. Secondly, I really like this set because it as a switch to allow me to select the light color (2700K, 3000K, 3500K, 4000K and 5000K). For now, to use my guest's bedroom as a temporary office, I'd prefer to have 5000K color as i need it to be cool white. But when I return it to a regular bedroom, I'll probably change it back to 3000K, which is more suitable for bedroom, this will save me from spending more money in the future to switch them out. These lights are very bright, made of good materials, feel solid and very easy to hook up and install. Definitely a good deal since it's only cost about $10/each.
