Description

The Knightsbridge ELENA 595x595mm LED troffer panel fits standard 600x600mm ceiling grids and delivers 4500 lumens from a 33W SMD LED array behind an opal polycarbonate diffuser. The panel offers selectable colour temperature switching between 3000K warm white, 4000K neutral white and 5700K daylight, adjustable via an internal switch without rewiring or changing components.

Designed for commercial installations including offices, schools, retail spaces and healthcare facilities, the ELENA includes a self-test emergency function with a lithium battery providing 280 lumens for a minimum 3-hour duration during mains power loss. The self-test feature automatically runs periodic checks at pre-programmed intervals, eliminating manual emergency testing requirements and ensuring compliance with emergency lighting standards.

The pressed steel housing with white powder-coated finish mounts into standard T-bar suspended ceiling grids, with the 595x595mm panel sitting flush within a 600x600mm grid aperture. The opal diffuser spreads light evenly across the panel surface, providing low-glare illumination with a CRI >85 and Tp(a) rating for unrestricted use in general commercial environments. The panel achieves 163lm/W efficacy at full output and carries a 5-year warranty excluding the emergency battery.

Product Specification Sheet

Frequently Asked

How is the colour temperature changed?

The CCT is adjusted via a switch located inside the panel housing. The panel must be removed from the ceiling grid to access the switch. Once the desired colour temperature (3000K, 4000K or 5700K) is selected, the panel is re-installed and the setting remains until manually changed again.

Does it fit a 600x600mm ceiling grid?

Yes. The 595x595mm panel dimensions are designed to fit standard 600x600mm T-bar suspended ceiling grids, sitting flush within the grid aperture with a small tolerance gap for installation.

What does the self-test emergency function do?

The self-test feature automatically runs periodic checks of the emergency battery and circuitry at pre-programmed intervals, ensuring the emergency function is operational without manual intervention. If a fault is detected, an indicator LED on the panel will alert maintenance staff.

What is the emergency duration and lumen output?

The lithium battery provides a minimum 3-hour emergency illumination at 280 lumens during mains power loss. The emergency mode can be configured as maintained, non-maintained or switched depending on installation requirements.
