A corn bulb is designed to retrofit commercial HID (High Intensity Discharge) lamps. The three most common HIDs are Metal Halide (MH), Mercury Vapor and High-Pressure Sodium (HPS) bulbs.
With a 360-degree beam angle and a high lumens output, an LED corn bulb provides optimal illumination to all commercial and industrial buildings. It is often used to replace aging high bay fixture lamps, post top lights, shoebox area lights, and security barn lights. It provides limitless applications in retrofitting any traditional light fixtures in damp, wet or even hazardous locations.
A corn cob LED light bulb is configured either with a built-in driver or external driver. It is available between 2000 lumens and 36000 lumens. It is ideal for replacing a typical 70 watt (W), 100W, 150W, 175W, 250W, 400W, 600W, and 1000W HPS or metal halide lamps. Corn Cob LED bulbs can achieve color temperature (CCT) ranges from 2700K (close to HPS lamps) to 5700K (daylight white light) and operate at 100V - 277V or 377V - 480V.
LED corn bulbs use up to 80% less energy (power), while producing similar or higher brightness than older HID lamps.
Corn cob LED lights last up to five times longer than a traditional metal halide bulb. With an average lifespan of 50,000 hours, this results in significant reductions in maintenance and replacement costs.
Corn lamps have higher lumen maintenance than High-Pressure Sodium (HPS) bulb. What does that mean? The LED lamp maintains a majority of its brightness throughout its lifetime, while a metal halide bulb quickly loses its lumens over time (up to 30% after only 5,000 hrs of usage.).
Not all LED lamps are created equal.
Over the years, we have been trained to buy bulbs based on wattage. However, watt is the measure of power and not the luminous flux (in simpler terms…brightness.) The unit for brightness is lumens. Since the lighting industry has decided to properly label all lamps with the correct measure of light, we simply need to retrain ourselves to retrofit our bulbs with the proper lumens output and not wattage (power consumption.)
Remember earlier, we stated that all LED bulbs are not created equally? Depending on the efficacy (lumen/watt,) some LED chips are more efficient than others. For example, a 150W LED corn can range between 15,000 to 28,500 lumens. So, when comparing two 150W corn bulbs, make sure to evaluate their lumens output.
