Key Features:Electronic Thermal Management ETM monitors the heat output of the LEDs and makes use of integrated Pulse Width Modulation circuitry in order to maintain safe operating temperatures in order to prolong the LED life span to its full 50,000 hour potential. Pulse Width Modulation The Evo Prime utilizes integrated Pulse Width Modulation (PWM) dimming circuitry to manage heat levels. PWM works by flashing the LED at a frequency faster than the human eye can detect, reducing the time that the LED is operating while still delivering 100% light output. Extruded 6061 Aluminum The Evo Prime is housed in 6061 extruded aluminum for ultimate strength and durability. IP-68 Rated The Evo Prime has achieved an ingress protection rating of IP-68, signifying that it is dust-proof and submersible in water up to 3 meters. Proven Mounting System The Evo Prime utilizes the Vision X signiture stud mounting system that allows for 15° of adjustability and helps to control vibration through the use of isolated rubber in the mount.
