Light Meter Analog
The Active Eye Analogue Light Meter is a simple to use, hand held meter that requires no batteries. It uses silicon sensors to “read” the light around your plants. There are three different ranges which you can use to measure different types of light. The X1 range is for fluorescent lights, the X10 will read sunlight levels, and the X100 range for high intensity artificial lighting ( HPS, HID, MH ). Simply switch the dial on the front of the palm-sized meter to move from low range to high. If you are testing a low range, and the meter maxes out, you can move up to the next to keep your reading accurate. Hold the light meter at plant level, pointed directly at the light source. The meter will give you a reading in Lux (lumens per square meter) and foot candles simultaneously.
