Light Efficient Design LED-8039E345D-A FlexColor LED Bollard / Post Top Retrofit Lamp - E26 - 18W - CCT Selectable - 2,610 Lumens - 120-277V

Light Efficient Design’s LED-8039E345D-A is a versatile LED retrofit lamp designed for bollard and post-top fixtures that previously used HID sources. The lamp is built to operate on 120–277V and features a medium E26 base with a corn cob form factor, delivering approximately 2,610 lumens at 18 watts. A key practical feature is its CCT-selectable capability, allowing users to set warm 30K, neutral 40K, or daylight 50K color temperatures via a side-switch, enabling one product to cover multiple lighting scenarios. The unit is dimmable to 50% when the “LO” setting on the switch is engaged, providing flexibility for energy savings and ambiance control in a variety of applications. With a rated life of 50,000 hours, this lamp is positioned as a long-life option for outdoor or semi-outdoor installations where maintenance intervals are a consideration.

Construction and design notes emphasize multi-directional mounting compatibility, meaning the lamp can be installed base-up, base-down, or sideways without compromising performance. The lamp is rated for enclosed fixtures and damp locations, and it includes protective features such as dual-stage MOV surge protection and basic moisture and vibration resistance. Operating temperatures span from -40°F to 122°F, which supports use in diverse climates. The design targets HID-to-LED retrofits by delivering comparable lumen output while offering immediate color-temperature selection and compatibility with existing E26 sockets.

Practical considerations for selection and use include its 18W rating and 2,610-lumen output, which can be a suitable replacement for conventional 100W HID equivalents in terms of brightness, though exact replacement equivalency should be validated for the fixture and environment. The fixture’s dimensions (approximately 6.3 inches in length and 2.6 inches in diameter) and base type are consistent with standard post-top luminaires, simplifying compatibility checks. With a durable, pre-tested driver assembly and potted construction, the lamp is intended to withstand field conditions typical of outdoor lighting retrofits, while offering selectable color temperature to optimize the lighting quality for different applications.
