I have a 12-28V 18W LED off road light bar up for auction. This light bar is 8" in length and has 6 LED's inside that totals to 1350Lm output. These are very bright! It are constructed out of a fully aluminum housing and has a polycarbonate lens. It can operate in -40c to +50c degree temperature and is waterproof to IP67 and shock resistant to 20g. It includes dual aluminum mounting brackets and can be used for many different applications. This light bar can be used for off road vehicles, rhinos, sand rails, quads, rzr's, etc. These are very nicely constructed and will last a long time! Good Luck!
