The lamp was super packed and designed also very sophisticated. The parts are simply plugged together without screws. The cover we attached with clips in which one side is equipped with hinges so that one remains the lid when tube replacement easy hanging on one side. The lower part can be completely assembled in advance and offers enough possibilities for ceiling mounting. In addition, material is delivered to hang the lamps.
When I have two tubes MASTER TL-D 58W / 840 Super 80 white ordered. Super fit and my workshop for the lighting quite good enough. (6x4m room).
One star deduction based on the price. It is simply brand chinaware.
