E-lite star™, a registered brand of Excellence Optoelectronics Inc.(EOI) for all outdoor and industrial LED lighting products, has announced the launch of new residential LED streetlight SL3c series with the promise of delivering payback in one year and up to 65% in energy savings.  The SL3c luminaire comes in 28W and 38W that can replace 70W to 100W equivalents of high pressure sodium (HPS) fixtures. Combined with the fact that it only weighs 5.44 kg (12 lbs) and has an output of 2940~3990 lm, it is now the right time for municipalities, small or big cities, utilities, and private owners to consider switching to LED lighting.
