Available now! Retrofit your tall wall pack unit with the Metal Lighthouse Retro Pack Mark 2! Units are designed to be used in wall packs like the one pictured on our spec sheet. These wall packs were manufactured by many different companies using HPS (high pressure sodium) and CF (compact fluorescent) lighting technologies. Our Mark 2 Retro Pack is designed to upgrade your wall pack from these older technologies to the latest generation LED components. Our 10 watt version (2L) replaces lower wattage CF builds and our 14 and 20 watt versions replace higher 50 and 70 watt builds. Up to 75% energy savings as soon as you install the unit!
