In addition to performing all of the protective tasks of a regular safety sleeve, the MATRIX allows you to regulate the light output or reduce lamp glare. By simply rotating the sleeve, you can adjust to your desired comfort level. The clear window of the tube allows the control of the light output, while the matrix patter of the Mylar insert allows control of the light intensity.


The Cadillac of tube guards, not created equal to the others. NaturaLux™ blocks U.V. rays, stops glare that cause eye strain and headaches and bring lighting closer to a full spectrum lighting (daylight).
