Pros
- It shines very brightly, enough for a room of 25 square meters. m, for a room of 12 sq. m is already too much - it hurts the eyes, you need to take the same one, but at 40 watts. It shines the same at any voltage in the network (up to 160 V), does not blink during power surges, the brightness does not change. Does not require any installation - screwed into a temporary cartridge hanging from the ceiling, and rejoice.
Cons
- The price bites.
