The common application of bay lighting is used for the lighting application in warehouses or stadiums. Conventional bay lights are applied together with mercury bulbs or MHL multi-metal bulbs, so there are also concerns on power consumption and pre-heating before turn-on. To tackle such application in the market, MEAN WELL specifically develops circular shape with a patent for LED driver, HBG series. Output wattage covers 60W/100W/160W/200W/240W and 300W.

Moreover, other outdoor power supplies such as ELG(C)/HLG(C)/HVG(C) series also can be used in the design of bay light fixtures. MEAN WELL has comprehensive solutions for all kinds of application.
