Light Control Film

Lex-Efx Light Control Film® is an innovative polymetric film on a substrate that directs light, by changing its appearance, distribution and uniformity.  On the lamp side, it has an aluminum dot or square specular patterned surface.  The reflectivity of the aluminum surface is greater than 80% and offers excellent directional control.  The varied dot patterns control the ratio of uplight-to-downlight, determine the downward distribution and provide primary lamp obscuration.  Please see the 'Specifications' chart on the back page for our complete offering.

Light Control Film is most effective in direct/indirect lighting applications, with T-5 and T-8 lamps.  It is also useful for wall mounted light fixtures using compact flourescent or incandescent lamps, where lamp obscuration and light diffusion is needed.  For signage applications, we have a gradient pattern that can retrofit most box signs for an immediate uniformity improvement.  Preliminary testing has shown a doubling of minimum light level, while uniformity was improved eightfold.  Results in individual box signs will vary.

Light Control Film is suitable for use up to 70°C with compact flourescent, T5 and T8 lamps operating.  When using HID lamps, the film's maximum temperature must not exceed 50°C.  Thermal tests should be conducted on each luminaire design to confirm appropriate lamp size for the application.
