The red light itself is really great. It is powerful and works well. However, the bulb is very heavy and the base that it is in with the clip is not very user friendly. It is hard to get the clip to stay on things. I ended up buying a different base to put the bulb in to make it more user friendly. But the bulb itself is wonderful!
