480V 347V LED Corn Cob Light Bulb 120W E39 Mogul Base - Efficient

In this review of the 480V 347V LED Corn Cob Light Bulb 120W, the bottom line is simple: this is a practical retrofit option for commercial and industrial sites that need a high-output replacement for 600W HID fixtures. The reviewer found the bulb particularly useful where wide input voltage range and high lumen output matter, and highlights that it is designed for quick installation with a ballast bypass. For facility managers and contractors wanting straightforward energy savings and bright 5000K daylight output, this lamp is worth considering.

Key Features

• Wide Voltage Range: Works across AC 110-500V including 480V and 347V, making it suitable for many commercial electrical systems.
• High Lumen Output: Produces more than 16,800 lumens, providing strong daylight illumination to replace 600W HID units in large spaces.
• Energy Savings: Rated to save up to 90% on electricity compared with comparable HID sources, reducing operating costs in large facilities.
• Simple Installation: Ballast bypass design lets installers screw the LED into existing E39 mogul sockets without replacing the entire fixture.
• Durable Performance: Built to fit both open and enclosed fixtures with high CRI above 85 and a high power factor for stable operation.
• Service Guarantee: Backed by a 3 year quality service offering direct support for replacement or troubleshooting.

Who It's For

This bulb is aimed at commercial electrical contractors, facility managers, and project teams overseeing warehouses, high bay installations, parking lot poles, or outdoor wall packs where a direct replacement for 600W metal halide or high pressure sodium is needed. Its wide input voltage and E39 mogul base make it useful in retrofits where rewiring or new drivers are impractical.

Those who should look elsewhere include residential users and small-scale environments that do not require such high lumen output or the E39 mogul base, and projects that demand a guaranteed long-term track record - some customer reports show mixed longevity results, so critical long-life applications may require staged testing first.

Pros & Cons

Pros

• High brightness with >16,800 lumen output suitable for large spaces.
• Works across a wide voltage range (AC 110-500V), including 480V and 347V systems.
• Easy ballast bypass installation saves retrofit time and expense.
• High CRI and power factor support better color rendering and electrical efficiency.

Cons

• Some customers reported mixed longevity and isolated failures, so performance may vary by installation.
• Large form factor and mogul base make it inappropriate for typical residential sockets or small fixtures.
