INTRODUCTION
This Sper Scientic LED light meter with color temperature
correction (model 850006) is specically designed to measure
modern LED bulbs over the wide range of color-temperature
varieties commercially available in today’s lighting industry.
This unique meter includes all the features of a standard
LED light meter and also has individual channels specically
designed to measure di󰀨erent color-temperatures of LED light
bulbs. A simple intuitive keypad allows you to begin using the
device immediately in Foot Candles (FC), Lux (Lx), or Luminous
Intensity (CD). The user can preset the source distance for an
even more thorough analysis, showing readings on the large
LCD display. With a Min/Max/Average, Auto-Ranging Intensity,
99-point internal memory, Hold function, and a single-button
zero calibration, this meter covers every available feature of
competitive light meters. Comes with a universal tripod screw
in a compact carrying case with 9V battery, lens cover, and
instructions.
