Daylight Indicator - Light Meter 

Light-DLI-W 

 

 

 
 
 
The Daylight Indicator - Light Meter is a 
simple and easy step in measuring the light 
intensity levels affecting your turf or crops  
and can be used outdoors, on golf greens, 
stadiums or inside a greenhouse or other 
structure. This water-resistant unit will 
compare light level intensities within or 
outside your greenhouse. Simply place it on 
the area to be tested and 24 hours later, it 
will display your Daily Light Integral (DLI). 
With a push of a button, the Daylight 

Indicator records light intensity for a 24-hour period and then calculates the Daily 
Light Integral (DLI). Real-time intensity levels are shown every 4 seconds in µmol
