Import 20w - 60w Led Industrial High Bay Light Bulb — Buy in wholesale FOB from Supplier in Taiwan

The 20W to 60W LED Industrial High Bay Light Bulb is a series of four wattage variants designed for industrial and commercial overhead lighting applications. The product operates across a universal input voltage range of AC90-270V, making it compatible with electrical systems in most global markets. Available power options include 20W (2310 lm), 30W (3300 lm), 50W (6141 lm), and 60W (7368 lm), each delivering progressively higher luminous flux measured in lumens. The correlated color temperature options are 6500K for cold white and 3000K for warm white, allowing buyers to select the appropriate lighting tone for their facility environment.

The housing construction utilizes Al6063 aviation-grade aluminum for the heat sink component, combined with a PC (polycarbonate) lens cover. The manufacturer claims a heat transfer coefficient of 217 for the aluminum body, which is engineered with directional cooling fins that utilize air mechanics for active convection cooling. This thermal management system maintains operating temperatures between 50 and 60 degrees Celsius, which the supplier states reduces lumen depreciation and extends LED lifespan. The E27 Edison screw base provides standard socket compatibility across most industrial and commercial lighting fixtures.

These high bay LED bulbs target warehouse operators, factory floor managers, and facility maintenance contractors seeking to upgrade from traditional HID or fluorescent high bay fixtures.
