Keystone Technologies LED HID Replacement Lamp — 54W, EX39, 4000K

The Keystone Technologies KT-LED54HID-EX39-840-D is a 54-watt LED HID replacement lamp designed to directly replace high-intensity discharge (HID) lamps in existing luminaires. The DirectDrive Gen 2 design operates directly from line voltage (120-277V) after ballast removal, eliminating ballast failures and associated maintenance costs.

Key Features

• 54W LED power consumption
• EX39 (mogul extended) base for HID luminaire compatibility
• 4000K neutral white color temperature
• 120-277V universal input voltage
• DirectDrive (Gen 2) — operates without ballast after bypass
• Designed as a direct HID replacement for retrofit applications
• Manufactured by Keystone Technologies, model KT-LED54HID-EX39-840-D

Applications

Used to retrofit high-bay, low-bay, and outdoor HID luminaires (metal halide, high-pressure sodium, or mercury vapor) to energy-efficient LED technology. Suitable for warehouses, manufacturing facilities, parking garages, gymnasiums, and outdoor area lighting where EX39-base HID lamps are currently installed.
