Extend all 15′ Hydrofarm lamp cords an additional 15′ with the Lock & Seal Lamp Cord Extension. Creates a water tight seal and makes it easy to hang your reflector 30-feet from the ballast — provides added flexibility when setting up your grow room. Works with Hydrofarm’s All System Cord Set. UL listed.
NOT RECOMMENDED FOR USE WITH LAMP CORDS LONGER THAN 15-FEET. (Some high intensity light systems may not work at long lamp cord lengths due to ignitor range restrictions.)
