Because the cover and reflector are integrated, it can only illuminate the front. In other words, it looks like a spotlight, but the amount of light is a fluorescent lamp lamp so it's not a big deal. I tried to remove only the reflector, but it did not go well. The cover is also a plastic, but the ball joint of the clip base is also full plastic so durability is questionable. I only use the lamp and I use it with another instrument. It was not very good shopping.
