Provides scientifically accurate (PAR) light readings under any light source, including LED!

  • Provides accurate PAR light readings from ANY light source
  • Full sun to full shade indoors or outdoors.
  • Artificial light sources (LED, High-Pressure Sodium, Metal Halide, Fluorescent, Halogen...).
  • Three modes of operation:
  • Instant Spot Measurement mode for PAR light readings.
  • Scan mode for quickly averaging PAR over an area.
  • DLI mode shows Daily Light Integral on the LCD (no computer needed).
  • Integral mounting plate for: stand, stake, lanyard & hanger hole, and magnet mounts.
  • Small size allows light readings in tight spaces without needing an external sensor.
  • ¼-20 threaded hole for mounting on camera tripods & stands.
  • Includes sensor cover & soft carrying case.
