A very nice light, well wrapped, easy to set up. Power "something here," the weight, material of the lamp are the perception of a valued lamp. When you switch on, it takes half a second until the lamp is on, this disturbs but not (then soe but also "all" to). The bulbs are not interchangeable. We have replaced the lamp a 300W halogen uplight. This lamp is not as bright as the 300W halogen lamp, but bright enough, 18 W LED always bright enough to illuminate the ceiling. The savings in electricity costs, the lamp design good illumination and the quality feel of favor of this lamp. Last but not least: a very fast delivery: Saturdays ordered Tuesday the lamp has arrived.
