This Digital Lux Meter is a pocket-sized, portable, Very Accurate light-sensitive instrument.
The output of HID bulbs diminishes gradually over time with use, but the human eye has difficulty discerning this reduced output.
Therefore, it is important that users have a way to measure the ongoing LUX from their lamp, in order to know when its output has declined to the point where replacement is recommended.
We Recommend Regular Globe Changes As Manufacturers always give “actual” globe ratings but few give “Intensity” / Time
We would Change say a Hps 600w globe running 18/12 Then 12/12 after 2 Crop Rotations
