We are surprised by the still very large for an LED light in this performance class light output. Fluter 20W and reading lamp 5 W, which is to use also mE well as object illumination and backlight. Both lamps are very beneficial to dim independently. The uplight can be "just" align upwards radiant, but does say the name already. For construction Have a look the radiator is really too bright! After a short light test we have ordered a second copy.
