Review on RAYHOO 1000 Lumens Non-Dimmable Incandescent Equivalent for Improved SEO by Casey Stevens

Pros: Slim, compact, cool and bright. Cons: High marriage level. Low CRI (Color Rendering Index): Colors are even, objects in the room appear lifeless. I bought two packs of 4 (8 bulbs total) of these RAYHOO 4000K corn bulbs. 2 lamps flickered and did not light up. 4 other lamps had a loose base and screwing/unscrewing the lamp from the socket caused the lamp to go out momentarily or the socket to remain in the socket. A total of 6 defective bulbs from a set of 8. I requested a replacement for both packs from Revain and was quickly sent a replacement which was delivered within a few days. The replacement was better, but one bulb had already died within a week. The bulbs are bright and have the 'bright white' 4000K hue I ordered, but the CRI (color rendering index) seems to be on the low side. Even if the room appears bright, everything in it appears flat and lifeless in color compared to another lamp set with a color rendering index of 95.
