An affordable meter that provides scientifically accurate Photosynthetic Active Radiation (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,
Florescent, 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).

Compact and easy to use.

Water and impact resistant.

Integral mounting plate for: stand, stake, lanyard & hanger hole, and magnet mounts.

1/4-20 threaded hole for mounting on camera tripods and stands.

Includes a sensor cover and soft carrying case.

OPTIONAL: Add on extension wand allowing you to reach deep into or across the canopy!
