Features : incase of error in cutting of pop holes. eg. you cut 3 watts pop holes and later realised that 3 Watts panel lights brightness won't be enough and there's a need to install higher wattage instead of widening the holes which will take more time all you need to do is adjust any size of panel lights clips or ceiling holder like 18w pops, 12w, 15w or 6w panel clips and install.
It has a unique shape, it's durability and brightness is topnotch.
