Have this lampholder ordered and received quickly. The operation is very gut.Man can adjust the brightness, in terms of light, as well as on-time. The only downside is that the total length is so large that it fits in no housing. It has to be turned up just a lamp. But has the advantage that you can use any lamp types and strengths. Also in the case that the lamp is defective, this kind of advantage. A BUY recommendation.
