Specifier FAQs

Common questions.

Why does tunnel lighting change through the tunnel?

Drivers entering a tunnel in daylight need time for their eyes to adapt. Tunnel lighting runs brighter at the entrance and reduces through the interior, so the change in light level never outpaces the eye.

Can the Crompton Alpheca be monitored and controlled?

Yes. Crompton tunnel lighting supports monitoring and control, so light levels can follow the daylight outside and faults can be picked up quickly.

Do you design tunnel lighting layouts?

Yes. We work from the tunnel length, cross-section and traffic speed to the entrance, threshold and interior zones, then quote the fittings for each zone.
