I took the first one (450С) for a room, probably less than 12 sq. m. There was clearly not enough light. Along with this, the lighting became acceptable. Nevertheless, I don’t understand those who write that for a room of 20 squares, one such 550s is enough. Maybe they take it for moles probably. I definitely do not have enough of it for 12 squares. But overall it's a good thing.
