Kosnic Nitro Emergency Downlight 3W 6000K Non-Maintained White

Kosnic Nitro DALI NTR03 3W DALI-2 Non-Maintained LED Emergency Downlight White.

The Kosnic Nitro DALI NTR03 is a discrete recessed LED emergency downlight built for seamless integration into DALI-2 managed lighting systems. Delivering 200lm from just 3W, with a compact Ø50mm cut-out and a 7-year battery life, it is designed for specifiers and contractors who need a low-profile, long-life emergency solution that fits neatly into modern ceiling designs without compromise.

DALI-2 Integration for Centralised Emergency Management

Full DALI-2 conformance to EN 62386-202 enables the NTR03 to be addressed, tested, and monitored from a central DALI-2 control system — removing the need for manual test rounds and supporting automated compliance records. Both automatic and manual emergency operation testing modes are supported, giving site managers flexibility in how routine checks are carried out. A built-in LED status indicator provides a clear local visual confirmation of operational status without the need to access the control system.

Discreet Recessed Fit for Any Ceiling

The NTR03/DA's compact Ø70mm face diameter and Ø50mm cut-out means it slots into standard ceiling apertures with minimal visual impact — an important consideration in commercial interiors, hotels, offices, and healthcare settings where aesthetics matter alongside compliance. At just 0.18kg, it places no meaningful load on ceiling structures, and the white finish ensures it disappears into the ceiling plane during normal operation.

Lens Options for Room or Corridor Applications

Two lens configurations are available: a standard circular beam pattern for general room coverage, and a corridor version with an asymmetric beam shaped to emphasise illumination along a single axis — ideal for escape routes, stairwells, and long internal corridors where directional coverage is required. Both variants deliver the same 200lm emergency luminous flux at a 45° beam angle.

Long Battery Life, Low Ongoing Maintenance

A 7-year battery life significantly reduces the frequency of battery replacement visits compared to many competing products, cutting ongoing maintenance costs across larger installations. The operating temperature range of 0°C to 45°C and Class II double-insulated construction mean no earth connection is required, keeping installation straightforward in standard internal environments.
