Diode Dynamics HP6 LED Bulbs

The Diode Dynamics HP6 LED Bulbs are designed for customers who want a brighter LED upgrade for compatible festoon-style bulb locations. These bulbs are commonly used in map lights, dome lights, trunk lights, cargo lights, and other compatible interior lighting applications where a factory festoon bulb is installed.

Each HP6 bulb uses eight high-power LEDs arranged in an omnidirectional pattern to deliver broad light output inside the factory lamp housing. Diode Dynamics lists the 29mm and 31mm HP6 versions at 130 measured lumens, while 41mm HP6 listings show output up to 140 measured lumens depending on configuration.

The HP6 design uses a frosted cover to help create even light distribution and a cleaner factory-style appearance. This helps reduce the harsh pinpoint look often associated with exposed LED chips while still adding a more modern LED lighting effect.

Built for reliability, HP6 bulbs include constant-current circuitry and transient suppression to help reduce flicker and premature failure. Durable metal terminals help the bulb fit snugly in compatible sockets, while the lightweight construction helps reduce the risk of vibration-related loosening.

The HP6 lineup is available in multiple color options depending on size, including Cool White 6000K, Warm White 3000K, Blue, Red, and Amber on select configurations. This gives customers flexibility for a modern interior lighting upgrade, traditional warm cabin lighting, or specialty accent use where permitted.

Whether customers are upgrading dome lights, map lights, trunk lights, cargo lights, or other compatible festoon locations, Diode Dynamics HP6 LED Bulbs provide a bright, clean, and dependable plug-and-play LED replacement. Now Available at LEER!
