The Iris Light control Tube is a simple highly functional accessory that adds even greater versatility to the LazerBrite Modular Light System.  

Use your Iris to:

Create a focussed spot that protects your night vision;  Attach one LB head, bulb pointing into the tube, side aperture closed, to produce a focussed spot without any side light emission. This creates a great hand held light that protects your night vision. 

Create the focussed spot plus a light at your feet;  use as above then open the aperture to put light at your feet as well as in front of you

Use the aperture only for a one way signal or a discreet light source;  Attach a second LB head to the other end blocking the focused spot, slowly rotate the side aperture to go from a tiny spec of light to nearly half the tube lit.

All LazerBrite products are made in the USA.
