I've looked everywhere for a replacement bulb that matches the brightness of my halogen floor lamp. Other lights are either too dark or too bright, but this one was spot on. I hooked it up to a power meter and measured that it draws 18 watts, not 20 watts in state, but I think that's close enough. was that every time I turned it on, the other LED lights in my room would light up even if they were off. From what I've read, this is caused by a "phantom power" issue. Other lights I've tried don't have this problem and this is just one. I tried both bulbs from the kit with the same result. As a result I had to return it, although it delivered decent brightness.
