Dapper Lighting 921DREV Features:

The Design: The sleek metal body of these bulbs not only looks Dapper, but they also serve a purpose by acting as a heat sink for the high-powered LEDs. The biggest limiting factor for LEDs is heat, which can shorten the lifespan or cause premature failure. When engineering these bulbs it was a huge priority to keep them cool for long-lasting reliability.

The Engineering: These bulbs use highly efficient 2835 SMD LED chips, which are controlled and protected by a constant current driver.
