The Satco 65-671 LED Full Cut Off Color Selectable Wall Pack is an excellent, cost-effective solid state LED solution for use on buildings. The DLC Premium Listed wall pack has an impact-resistant polycarbonate lens and a die cast aluminum bronze finish. This model consumes just 40 watts of the universal 100-277 voltage. These 40 watts produce between 4,800-5,000 lumens, of either 3000K bright white, 4000K cool white or 5000K daylight, with a total CRI of 80. These fixtures are suitable for wet locations (IP65 Rated), have a 50,000 hour rated life, and feature a 5 year warranty. They have an integrated 4KV surge protection with a beam angle of 90x100. For additional costs, you may purchase an add-on photocell that is used to help with energy usage. When the sun sets, these wall packs will turn on. When the sun rises, they will turn off - saving you from unnecessary energy bills.
