The LCAM measures the level of luminance, or brightness, created by natural light at the tunnel entrance / exit to ensure that the visual perception of drivers will be maintained, both day and night, by avoiding sudden variations in lighting levels and potential “black hole effect” when entering and exiting a tunnel.


The ILCAM measures the level of illuminance within the tunnel bore to ensure interior illumination levels are being continuously maintained, in order to affect safe lighting conditions for drivers.

TLACS-U (Underpasses and short tunnels)

This version of TLACS is a turnkey solution for controling and dimming for underpasses and short tunnels.


Offered in 2 versions – individual or group lighting control and monitoring, TLACS-U is the perfect solution for underpass or small tunnels with a maximum of 50 luminaires.

TLACS-RDE (Group Dimming)

In this version specifically designed for dimming, TLACS-RDE adjusts the lumens according to the luminaire’s location in the tunnel.   The adjustment is made per a signal received from the photometer.  TLACS-RDE can also switch ON/OFF the luminaires usually installed in the threshold of the tunnel.

TLACS-EM (Energy Management)

The TLACS-EM is the most complete and technologically advanced solution on the market.  It addresses lamps individually, by tuning them on and off, as well as controls and supervises lamp status and consumption.
