Why is the light output low on my Wacker Neuson LTN 6L?

If your Wacker Neuson Lighting Equipment has low light output, the lamp may be degraded and need replacement due to normal lamp life. Another potential cause is low ballast output, so check the ballast for proper voltage output. Additionally, a dirty fixture or lens can reduce light, so clean the reflective surface inside the fixture and both the inside and outside surfaces of the glass lens.
