Review on 🔆 ASD 4 Inch LED Retrofit Recessed Lighting, Baffle Trim, CRI 90, 9W (40W Replacement), Dimmable Ceiling Light, 600 Lumens, 4000K Bright White, Round Downlight, Wet Rated, Energy Star, ETL Listed by Terrance Duncan

These lamps at 4000K offer good color and light intensity. Great for the kitchen or other room where I like bright white light without a noticeable "blue cast". Some might not like this for bedrooms or similar, but with the help of a dimmer switch the brightness can be regulated according to personal preference. The dimming rate was different than current LED bulbs, so mixing and matching is not recommended for a specific dimmer. I found that with my dimmer, these lights would not light up at the current minimum dimmer setting, but my existing previous LEDs would light up. No flickering was observed for these lamps at any dimmer setting. I can't comment on the durability as I haven't used it for a long time.
