Smart Spring Downlight

Smart design for easy-installation.
Laurence and our R&D group had been working on the smart spring for 9 years. On April o6, 2006, Laurence flew back to Chengdu which is his hometowm. During the flight he saw the small table in front of his seat which could be locked automatically. He suddenly got the idea to design his Smart Spring. I was a revolution for downlight installation. He believes the electricians will surely like this mechanism.
