Review on Lamp LED Yeelight Halo Ceiling Light YLXD50YL, 52 W by Dorota Wirkiewicz ᠌

At 50s, the rim very strongly extinguishes the light to the sides, straight with or without a ceiling lamp, earth and sky. I read on the forums about foil, but still not ice . more precisely tolerant, but worse than C450))) Made measurements at 4000K (using the Yeelight application) with the LUX Light Meter program. Ceiling height 2.8m, telephone on the floor under the ceiling in the most central position. More than 10 attempts were made and all the time the readings are different. I do not know why, although what to expect from a phone with an amateur program. А2022С450 210-225 lux YLXD50YL (with foil :) )190-200 lux Now about quadrature. If your room is square (I have 4.5x4.8m), then there is enough light for 20 squares. But if it is outweighed into a rectangular one (6x3.3m), then that's it, its limit is 15-16 meters and then there will be a bomb. It’s already dark in the corners, who has children, in principle, is critical . Conclusion: take the C550, the Chinese position it at 20-25m (C450 at 10-15m and it more than fulfills them, and even with a margin in a square room).
