Use the LI‑1500 with one sensor to sample and log measurements up to 500 Hz — fast enough to measure the flicker rate of fluorescent, iridescent, incandescent, and LED light bulbs. Graph these large data sets on your computer using LI‑COR’s FV7x00 software, available for free download. Also view real-time light measurements, GPS data, and other variables on the eight-line display screen.
The LI‑1500 features an optional global positioning system (GPS) for recording the location of measurements. The GPS facilitates repeated visits to the same location for tracking light levels over time. GPS data can be logged independently or with light data.
