FOCAL ADJUSTMENT
First, loosen the three set screws on the lens tube cover and remove the lens tube cover.
Power on the fixture. Be sure to never look directly at the LED while the fixture is on.
Now, move the primary optic as close to the LED as possible and the secondary optic as far from the LED
as possible on the optic slider rails. Slowly begin sliding the secondary optic toward the LED until the
projected image comes into focus. This will be the narrowest focused beam the fixture can achieve.
To widen the beam move the primary optic forward about 1 mm, and then move the secondary object
backward along the optic slider rails toward the LED until the beam comes back into focus. Repeat this
process until you have your desired projection size. At the maximum beam size, the primary and
secondary optics will be touching each other at about 1/3
rd
of the length of the optic slider rails.
When you have finished focusing the lenses, replace the lens tube cover and tighten the set screws back
down to hold the lens tube in place.
