A:Answer Actually that's incorrect. The ambiance bulb is the dimmest BR30 that Hue sells. The non-ambience, non color changing Hue BR30 is (at least) 150 lumens brighter. It's less than 3000K color temperature so closer to a warm old incandescent bulb. I can't actually find any specs for color temp range for these adjustable ambience bulbs, but at 650 lumens, you'll need more than one bulb to light any area you actually need to see in.
