A new generation of recessed downlight fixtures. Lightweight and efficient. Backlit structure. LED beads moved from side to back, so it became more power efficient. The driver is integrated into the light source module, so it doesn't require any additional mounting space. 27mm thickness of the lamp expands the variety of its installation area. Thanks to the wide edges, the size of the mounting hole may vary within about 1 centimeter. The outer shell is made or 100% fire-proof plastic, still tenacious and preventing cracking. The diffusion place is made of anti yellowing material with excellent translucent effect. No perceptible flicker light comfortable to the human eye, does not cause irritation over long operation time. Several powers within one series will help to light up different rooms in the house or divide one room into different lighting zones.
