If you need reliable lighting for freezers, cold storage, or other wet environments, this Kason 1810LC LED light fixture is built specifically for the job! This 4-foot vaporproof fixture is designed to operate in temperatures from -40°F to 104°F (-40°C to 40°C), making it perfect for walk-in freezers, refrigerated warehouses, and other low-temperature applications. The 39W LED system delivers an impressive 3770 lumens with 96 lumens per watt efficiency, exceeding Federal Energy Act requirements while providing bright, consistent illumination. Unlike traditional fluorescent lights that take forever to warm up in cold temperatures, this LED fixture provides instant full brightness even in the coldest environments. The IP65 rating means it's completely protected against dust and low-pressure water jets from any direction, so it can handle wet conditions without issues. The unbreakable polycarbonate enclosure is tough enough to withstand impacts and harsh environments, while the frosted diffuse creates even, glare-free lighting. There are no tubes to replace since the LED strips are pre-installed, and with a rated life of 50,000+ hours, you won't need to worry about maintenance for years. The universal 100-277VAC input works with most electrical systems, and it draws only 0.33 amps, helping reduce your energy costs. It's UL Listed for US and Canada, RoHS compliant, mercury-free, and has been LM-79 and LM-80 tested for performance verification. The fixture measures 46-7/16\L x 4-23/32\W x 3-9/32\H and comes with a 5-year limited warranty. Whether you're upgrading existing freezer lighting or installing new fixtures, this Kason LED light provides the reliability, efficiency, and performance you need for demanding cold and wet environments. The energy savings alone can often pay for the fixture within just six months of use!
