LED lamp

ZSL-211

The lamp was designed for lighting vehicle interiors where a strong light source is required and low power consumption and high durability are important. The lamp uses white LEDs with a high colour rendering index (CRI). Thanks to a large number of low-power LEDs, the light source is diffused and does not cause the glare typical of small-surface light sources. The lamp is equipped with LED current stabilisation, so its brightness does not change with supply-voltage fluctuations.

The ZSL-211 lamp is installed in the vehicle headliner. Typical applications include ambulance medical compartments and office vehicles. Compared with fluorescent lamps, it is much more durable and insensitive to frequent switching. The cover is made of transparent polystyrene with a frozen-ice texture.
