Internal Lens Condensation


The inside of the output lens has condensation on it.

Description/Explanation of Issue

Too much internal humidity will cause condensation on the inside of the output lens. 


  1. With the fixture powered on, view the Humidity amount in the Info menu. The goal is to have humidity at 10% or less. Note: Viewing Humidity under display battery power will show 0% so the fixture must be powered on to see the correct humidity level.
