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 Buffy Foley

These 4000K bulbs offer good color and light intensity. Ideal for the kitchen or other room where I like bright white light without a noticeable "blue cast". Some may not like this for bedroom or similar, but with a dimmer switch, the brightness can be selected according to personal preference. The dimming speed was different than current LED lights, so it is not recommended to mix and match them for a specific dimmer switch. I found that these lights would not light up with my dimmer high would ra at the current minimum dimming setting, but my existing previous LEDs did light up. The flickering of these lights was not detected at all dimmer settings. I can't comment on the longevity of the Vity as I haven't used it long enough.
