80W LED RETROFIT CORN BULBS LIGHT E39

80W LED Retrofit Corn Bulbs Light E39 80W LED Retrofit Corn Bulb offers exceptional lighting with a variety of wattages and lumens ideal for commercial and industrial use. It's also designed to easily replace HID and CFL bulbs but with the same colour temperatures (5000K / Day White), providing uniform and bright lighting for all areas such as warehouses, factories, workshops, and outdoor applications. Operating on a wide voltage range (100-277VAC), they can be powered by a variety of electrical systems. Integrated "Active Cooling" via a Sunon fan and Aluminum Fin Heat Sink provide superior heat dissipation for longevity and stability. 80W LED Retrofit Corn Bulb produces light with a beam angle of 360°; utilizing a frosted or clear (PC) lens to minimize light glare and maximize the effective distribution of light. They have been tested to withstand 6kV of high voltage surge protection, putting them in the category of extremely durable products that provide safe, reliable, and consistent service. 80W LED Retrofit Corn Bulb is UL and cUL marked; CE approved and DLC listed, meeting all required performance, safety, and quality requirements for commercial and industrial retrofit projects. Primary Attributes Efficiently uses 80 watts of LED light Daylight light output with a color temperature of 5000K Can be used with fixtures that have an E39 base (also works with E26, E27, and E40 bases) Will operate at voltages ranging from 100 volts to 277 volts AC Uses a Sunon fan for optimal cooling and temperature control Uses aluminum fins for superior thermal performance Frosted or clear polycarbonate cover Provides 360 degrees of uniform light distribution Good for use in high voltage applications, as it has 6kV of surge protection C-UL, c-UL, CE, and DLC certified Technical Specifications Specification Details Model CIRC-RCL-80W Power Output 80W Color Temperature 5000K Input Voltage 100–277VAC Base Type E39 (supports E26, E27, E40) Beam Angle 360° Cooling Method Sunon fan active cooling + aluminum fin heat sink Cover Frosted / Transparent PC cover Surge Protection 6KV Certifications UL, cUL, CE, DLC Key Uses For retrofitting (replacing) existing industrial/commercial lighting applications Used to replace an HID or CFL bulb in any new or existing applications Warehouses, factories, and workshops Used outdoors for parking lots and canopies Energy-efficient lighting for either indoors or outdoors Why LED Retrofit Corn Bulbs Bright light comes from LED Retrofit Corn Bulbs, while lasting a very long time without using much power. Daylight-like clarity fills spaces with the 80W version, which also handles heat better than most. Safety certifications back up its performance claims quietly behind the scenes. Choosing this bulb for upgrades just makes sense in hindsight. Related Products CIRC 36W LED Retrofit Corn Bulbs Light E26/E39 CIRC 300W16SX New LED Corn Light 300W 80 watts - what HID does that actually replace? Roughly 250-watt metal halide or 320-watt high-pressure sodium. The LED throws light in all directions while HID focuses in a box pattern, so ground-level illumination ends up comparable or better despite lower wattage. Plus instant-on, no warm-up, no color shift as it ages. Active cooling with a fan - won't that break first? Sunon builds industrial-grade fans rated for 50,000+ hours. At 80W, passive cooling struggles without massive heat sinks. The fan plus aluminum fins keeps junction temperatures reasonable in a smaller package. Trade-off is worth it for high output density. Fan failure modes are gradual - noise increases before death, giving warning. E39 base - what about E26, E27, E40 claims? E39 mogul base is native. The "supports" language means adapter sleeves can step down to E26 medium or step up to E40 giant mogul. E27 is European intermediate, less common in North America. Check your socket size before ordering adapters. Most 80W applications are commercial fixtures expecting E39. Frosted versus clear cover - which do I want? Frosted diffuses the LED points, reduces glare when viewed directly, softens shadows. Clear maximizes raw output and throw distance. High bays and deep fixtures often want clear. Areas where workers look up at the fixture, or where aesthetics matter, frosted wins. Same lumen count, different distribution character. 6KV surge protection - industrial zones need this? Motor loads, welding equipment, large HVAC cycling - all inject noise on industrial circuits. 6KV rating means the bulb survives what kills consumer-grade LEDs. Also helps with lightning-induced transients on outdoor pole installations. Cheap insurance for hard-to-reach fixtures. 100-277V - my building has 480V three-phase? 480V line-to-line is 277V line-to-neutral on wye services. This bulb handles 277V nominal, which is the common commercial high-leg. True 480V single-phase or delta services need different gear. Know your electrical topology before specifying. DLC listed - rebate math? Many utilities pay $10-50 per fixture for DLC-qualified retrofits. Check local programs. The 80W hits efficacy thresholds for most incentive structures. Independent third-party testing verifies lumen and watt claims. Paperwork burden is worth it for multi-bulb commercial jobs. How loud is the fan? Sunon specs around 30-35 dB at one meter - roughly quiet office background. In industrial settings with machinery, invisible. In quiet warehouses after hours, barely perceptible. Not silent like passive-cooled smaller corn lights, but far from objectionable. 300W corn light exists - why stop at 80W? Different applications. 80W fits high bays, wall packs, shoeboxes. 300W replaces street lights and area lights with massive output needs. Thermal management scales dramatically. This 80W hits the sweet spot for common commercial retrofits without requiring heroic cooling engineering.
