The Light Efficient Design LED HID Retrofit Bulb, model LED-8039E57-A, is specified at 18W, 5700K. This model is an LED replacement lamp for a compatible fixture using its E26 base and lamp envelope. Evaluate it as a retrofit lamp in the specified fitting rather than a general household bulb. The operating arrangement for this model must follow its exact instructions, including any required ballast removal or compatible-ballast condition.
Plan the electrical connection around this model’s 120-277V AC rating. Compare length 5.31 in., diameter 2.59 in. with the available space for the lamp compartment, especially when retaining an existing enclosure or shade. At 2695 lumens, this model can be compared by light output when planning the existing fixture’s illuminated area; the final appearance depends on the fitting and its placement.
Buying tip: Check the existing socket for the E26 base and compare the available clearance with the lamp dimensions.
