Exterior 420

For white light designs requiring the added flexibility of color temperature control from warm to cold white, the Exterior 420™ offers one of the most powerful white light units on the market, with even output across a wide color temperature range.

The Exterior 400™ Range

The outdoor installation market now has the best combination of powerful, compact and energy-efficient LED light fixtures. No matter the application - long or short throw, cold or warm white, dynamic or static color - the Exterior 400 Range does it all.

  • Perfect color temperature control from warm to cold white
  • Very high efficacy
  • No color separation or shadows due to use of premixed LED


  • Extremely bright white light (5900 lm) with color temperature control
  • Very broad color temperature range (2700 - 6500 K)
  • Very low power consumption (max 139 W)
  • Choice of beam angles - 8°, 14°, 33°, 54°
  • Color calibration ensuring uniform colors across fixtures
  • Internal power and control
  • Super rugged IP65 housing
  • Choice of white, black or aluminum housing
  • 0 – 100% intensity control
