LED corn bulbs offer a cost-effective solution to upgrading existing high bays, low bays, parking lot shoeboxes, wall packs, and post-top lights. Retrofit corn bulbs deliver energy savings and enhanced light output with the need to replace the existing fixture. With significantly longer lifespans than traditional HID or MH fixtures, maintenance costs are reduced. We offer corn bulbs in medium E26/E27 or mogul EX39/E39 screw bases and a wide variety of comparable wattages to help you find the right bulb for your facility.
