Have the unit equipped with a timer and thus works perfectly. Can also be operated with brightness sensor - but I have not used -with the switch at least I can also program different times for ON / OFF. I put it into a large living room about 50 square meters and it actually manages outwardly to almost the same "flicker effect" to produce as our 42 inch television -was skeptical whether it is not too small, but it was unfounded. In summer 3 weeks without problems works! -The Need not be the expensive model also doing great.
