This lightbulb Does exactly what is says. Irthas an array of colors and they are bright enoug...mostly ambient, but most importantly the white light is nice and bright. But one of the best features of this light is that it works well with Alexa which is helpful when walking into a dark room. Set-up was fast and easy the directions were step-by-step and easy-to-follow. The bold is universal and can screw into any kind of desktop lamp.
