Product DescriptionThe X-1 is the first in the series that features our proprietary fan technology to keep things cool. This allows us to power the single emitter LED to the maximum yet maintain optimal working temperature and color. The miniature fan is wedged between two heat sinks and is programmed to kick on when temperatures exceed the optimal range. This equates to a powerful, long lasting light that does not overheat or fade over time.
