  1. Signal obstruction lighting

    Did you know that QL Lamps are still used in many lightpoles of MacDonalds and that QL lamps are in the clock of the Big Ben in London for 20 years now?.

    Also a QL lamp is placed in a waterproof, red colored luminaire on many high buildings, towers, masts, cranes in the Netherlands.

    In Los Angeles, the traffic signs are lit by QL at night.

    The main feature of the QL lamp (highest reliability, ultra long lifespan) makes it very suitable for this application.
