SKU: 8-E40-CN120-CCT-UD
The 8-E40-CN120-CCT-UD is a 120W LED corn light with an EX39 (mogul extended) base, designed as a direct replacement for 400W MHL, HPS, and HID fixtures in commercial and industrial applications. CCT is field-selectable among 3000K, 4000K, and 5000K via an onboard switch, and the unit accepts both E39 and EX39 sockets. Typical installations include warehouses, parking garages, supermarkets, and enclosed high-bay luminaires. The lamp delivers up to 18,600 lumens at 4000K with an efficacy of 155 lm/W, and maintains a CRI greater than 80 across all color temperatures. Input voltage is 100–277V AC, 50/60 Hz, supporting 0–10V continuous dimming. The driver carries 6kV surge protection (L-N), and the IP64-rated housing suits damp locations. Operating temperature range is -40°C to 50°C. The unit uses Lumileds SMD2835 LEDs mounted on a PC and aluminum housing with a passive heat sink and no cooling fan. The product is UL and cUL listed. The warranty is five years based on 24/7 operating hours at 25°C in an installed fixture. Installers should bypass or remove any existing ballast prior to installation; the fixture is not compatible with external dimmers despite the integrated 0–10V dimming driver.
