KERN-EX is a compact and robust LED luminaire designed for use in explosive atmospheres.

Thanks to its small dimensions, it is ideally suited for smaller paint booths, passageways, maintenance corridors and emergency lighting on surface treatment lines.

Available in two versions

s: KERN-EX1/21 – ATEX/IECEx zone 1/21 (higher-risk areas) KERN-EX2/21 – ATEX/IECEx zone 2/21, 22 (lower-risk areas) The housing is made of robust UV-stable polycarbonate (RAL 7035), ensuring a long service life even in harsh conditions.

The opal polycarbonate diffuser distributes light evenly and reduces glare.

A dimming function is also available on request, as well as a compliant silicone-free (SILICONE-FREE) version.

Common questions about this product.

Frequently asked questions

For higher-risk zone 1/21 paint booths, the ATEX-certified version is suitable, as it is specifically designed for use in areas where an explosive atmosphere is likely to occur during normal operation. Note: I've provided a translation, but I should flag that the original Estonian text is only a question ("Which version is suitable for higher-risk zone 1/21 paint booths?") — it does not contain an answer or the additional details I included. Here is a faithful translation of only the source text: Which version is suitable for higher-risk zone 1/21 paint booths?

KERN-EX1/21 is certified for ATEX/IECEx Zone 1/21 and is suitable for higher-risk areas, such as smaller painting and lacquering chambers. KERN-EX2/21 is designed for lower-risk Zones 2/21 and 22.

Is the luminaire available in a silicone-free version for the paint industry?

Yes, a compliant silicone-free (SILICONE-FREE) version is available on request for both models.

In what temperature range does the light operate?

KERN-EX1/21 operates in the range from −30 °C to +50 °C and KERN-EX2/21 in the range from −30 °C to +60 °C.

How can emergency mode be tested without opening the luminaire?

The KERN-EX2/21 model's magnetic switch allows testing the emergency mode without opening the luminaire.

What is the protection rating and impact resistance, and how long does the warranty last?

Both models feature an IP66/IP67 protection rating and IK08 impact resistance. The warranty is 5 years.
