The first lamp worked around four weeks properly, then the spotlight flashed only in the three-second intervals, and although constantly short, he also turned not from but remained in continuous flash mode. Changes to the settings brought no improvement >>> return and exchange unfolded smoothly.
The replacement lamp worked around a week perfectly, then the same problem, light flashes only permanently, the behavior can not be changed by changing the settings. Even after the power was interrupted flashed the spotlight after the reconnection of the electricity merrily.
It would seem that the motion had twice in succession a quirk.
After the assembly work is not insignificant, I'll buy again this product in any way.
