I have bought several of these lights for the dome and map lighting in my car. They are brighter than conventional incandescent bulbs and produce pure white light. They also work well in the dark (my car dims the lights a few seconds after you close the door). Although expensive, they seem to be much better built than the cheaper, brighter LED lights I've bought. Others varied in length, and some were too large for the torso. They also made an uncomfortable buzz when dimmed.
