The Customized 12 watt IP54 5000k Round and Square LED Ceiling Light type developed a lot from the former halogen lamp type, energy saving type to led bulb type. But normally it is thick and big as bread. To have a different appearance to meet different taste, Runwin launched this LED Ceiling Light Round and Square with much thinner look. We call it Neptune series, with slim body, round and square type, power supply from 12W to 24W in different sizes.
