What does the beam lamp and the shake head lamp have?
In effect, the light beam angle is relatively small, can form a very bright light; head light, you should be the pattern of discharge lamp bulb, although there are light, but not so bright,
If it is a small scene, the speech of the leader, the leader of the illumination light dizzy miserable, hey
the beam angle is relatively large, the requirements of different applications, the effects are not the same, is not a kind of light, light the recommended distance is twelve meters away, if too close so bright as uncomfortable.
