Light Efficient Design LED-8136M50D LED High Bay Retrofit Lamp - EX39 - 90W - 5000K - 12,900 Lumens - 120-277V

Light Efficient Design LED-8136M50D is a high bay retrofit lamp designed to replace 150- or 250-watt HID fixtures with a 90-watt LED solution. It features a Mogul EX39 base and is intended for open fixtures and damp locations, making it suitable for warehouses, distribution centers, and similar industrial settings where high-output, low-maintenance lighting is valued. The lamp delivers about 12,900 lumens at a 5000K color temperature, offering bright, neutral white illumination that helps with visibility and safety in large spaces. Its 120-277V input supports versatile electrical supply conditions, and the unit is 0-10V dimmable to support varying lighting needs and energy-management strategies.

A key design emphasis is on reliability and quiet operation. The driver is designed and pretested in the USA, with a robust build that is burnt in three times prior to shipping and protected against vibration and moisture. The lamp operates in temperatures from -40°F to 122°F, which broadens suitability for freezer zones or hot industrial environments. The fixture is fanless, contributing to silent operation, and includes dual-stage MOV protection with 10kA surge protection to help guard against electrical transients. The product is rated for 50,000 hours of operation, providing extended intervals between replacements and maintenance.

When selecting this retrofit, consider the compatibility with existing open high-bay fixtures and the need for a ballast bypass configuration (Type B). The EX39 Mogul base ensures a direct screw-in fit for compatible housings, while 90W of LED output aims to match or exceed the lighting performance of a 250W HID reference. This lamp is designed for damp locations and open fixtures, so it is not intended for enclosed or fully sealed environments without verifying enclosure suitability. Package and channeling details are not listed, so verify mounting and electrical wiring requirements with your fixture before purchase.
