Description
x300W16SX New LED Corn Light 300W 5000K E39 100-277VAC PC Cover
Bright light comes from the 300W16SX LED Corn Light, built for big spaces needing strong output without high power use. This one runs on a 5000K shade of white, close to real daylight, helping visibility where it matters most. Instead of an ordinary socket, it uses an E39 fitting, making installation possible in heavy-duty fixtures. Factories often choose this type because it holds up under tall ceilings. Warehouses benefit too, since open areas gain clarity when lit evenly. Parking zones stay visible at night thanks to their steady beam. Large rooms indoors find enough coverage without adding extra units.
A broad 100–277 VAC range lets it run steadily on different power setups. Without a fan, heat moves quietly through solid surfaces instead. Packed tight with conductive paste, the driver sheds warmth more effectively since it sits apart from the main unit.
A wide 360-degree spread lets the 300W16SX fill spaces evenly, leaving no dark spots. Built with top-grade Rubycon parts, it runs steadily over time - while surviving strong power spikes up to 6,000 volts during testing.
This LED corn light carries approval from UL, cUL, ETL, cETL, CE, plus DLC - showing it lines up with key benchmarks for safe operation, output quality, and energy use.

Reasons for Selecting LED Corn Lights
LED Corn Light provides a combination of excellent brightness, energy savings, and long life. The 300W16SX is the perfect fixture for commercial and industrial buildings by providing long-lasting life, passive cooling, and quality materials for reliable operation.

300 watts - what did that used to take in old technology?
Roughly 1000-watt metal halide or 1500-watt high-pressure sodium. The LED spreads light in all directions while HID focuses in a box pattern, so ground-level illumination ends up comparable despite the wattage gap. Plus no warm-up, no restrike delay, no color shift to orange as the lamp ages. Maintenance crews stop climbing lifts every 12 months.
Fanless at 300W - how is that even possible?
Massive heat sink surface area and conductive grease between isolated driver and housing. The 16SX designation suggests a larger diameter than 9S or 12S siblings. Passive cooling works when you have room to radiate. Fixture must have some airflow - sealed housings cook any bulb eventually. But no moving parts means no bearing wear, no dust clogging, no noise.
E39 mogul base - anything bigger exist?
E40, rarely seen in North America. E39 covers virtually all commercial and industrial sockets. The 300W pulls serious current, so wiring and socket must be rated appropriately. Just because the base fits doesn't mean the fixture can handle the thermal or electrical load. Check ratings before retrofitting.
5000K daylight - any warmer options at 300W?
Commercial and industrial applications overwhelmingly want 5000K for alertness and visibility. Street lighting sometimes uses 4000K or 3000K for residential areas, but warehouses, factories, parking lots - all want the blue-white punch of daylight. Color rendering and perceived brightness both favor cooler temperatures for task and safety lighting.
6KV surge - lightning protection?
Indirectly. Direct strikes vaporize anything. But induced surges from nearby strikes, utility switching, large motor loads - 6KV handles those. Industrial zones with welding equipment or big HVAC systems generate electrical noise. The 300W investment deserves protection against invisible threats that kill cheaper electronics.
Rubycon capacitors - same as smaller corn lights?
Same philosophy, scaled for 300W thermal stress. Capacitor failure is the leading driver death mode. Premium parts rated for 105°C operation with long life ratings. At 300W, component quality matters more than at 27W. The manufacturer didn't cheap out on the flagship wattage.
100-277V - my facility has 480V?
480V three-phase wye gives 277V line-to-neutral. This bulb handles 277V nominal, which is the standard commercial high-leg. True 480V single-phase or delta services need different gear. Know your building's electrical service type before specifying. The wide range helps, but 277V is the ceiling.
PC cover - glass would melt?
At 300W, glass thermal shock risk is real. Polycarbonate handles temperature swings better and won't shatter from impact. Slight lumen loss versus bare LEDs, but safety and durability win. Cover diffuses the intense point sources into a more uniform glow. Workers can look up without spots in their vision.
360-degree beam - waste or feature?
Depends on fixture. Shoeboxes and wall packs have reflectors that capture upward light and redirect it. High bays with open bottoms benefit from the omnidirectional throw. Some waste occurs versus directional LEDs, but retrofit simplicity often trumps perfect efficiency. One screw-in replacement versus rewiring for new fixtures.
