Cluster Bulbs (Corn Bulbs), are comprised of Surface Mounted Diode Chips printed on circuit boards in which the chassis is comprised of aluminum for maximum heat dissipation. Our cluster bulbs use direct line voltage with no ballast. Commonly used to retrofit wall packs, pole lights, high bay ceiling lights in gyms, warehouses, factories and more. We've enlisted one manufacturer for all of our cluster bulbs based on their quality and performance.
