The compact and lightweight LED tunnel lighting "STAR LED'S TUNNEL" has been registered in the NETIS (New Technology Information System).
Star and Electric have released a compact and lightweight LED tunnel lighting fixture, "STAR LED'S TUNNEL," which has been registered in NETIS (New Technology Information System). Registration No. TH-150008-A. - A small and lightweight LED lighting fixture used for tunnel lighting installation. Our conventional LED tunnel lighting fixture weighs approximately 16 kg, while the new LED tunnel lighting has reduced this weight by about 62% to approximately 6.0 kg. - The housing size has been minimized, and the main body of the lighting fixture has been changed from stainless steel to aluminum. - By lightening the LED tunnel lighting fixture, workability has improved, reducing the load on civil engineering structures. - Due to the reduction in weight of the fixture, the strength calculations have allowed for a change in the number of anchor bolts from four to two, leading to labor savings and cost reductions in installation. - By adding a protrusion for height measurement on the side of the lighting fixture, measurements that previously required two people can now be performed by one person. Applicable range: highways, national roads, and local roads.
