Description

The Knightsbridge ELENA is a 595x595mm LED troffer panel light with selectable colour temperature (3000K, 4000K or 5700K) and dual wattage output (23W or 33W), delivering up to 4500 lumens through an opal polycarbonate diffuser. The CCT and wattage settings are adjustable on installation via built-in switches, allowing the output to be tailored to the room without changing the fitting.

Designed to fit standard 600x600mm ceiling grids in commercial offices, retail, education and healthcare settings, the panel sits flush with suspended ceilings and provides wide-angle general lighting. The pressed steel housing and polycarbonate diffuser construction gives a robust, lightweight panel that can be clipped into modular ceiling frameworks without additional support. The Tp(a) rating allows unlimited use in general applications where flicker and stroboscopic effects need to be minimised.

At 33W the panel delivers 163 lumens per watt, making it suitable for high-bay installations and spaces with extended operating hours where energy efficiency reduces running costs. The CRI of >85 provides accurate colour rendering for office work, product display and task areas. The IP20 rating suits dry indoor environments, and the Class I construction requires an earth connection. L70B50 of 60,000 hours means the panel maintains at least 70% of its initial light output for approximately seven years under continuous operation.

Product Specification Sheet

Frequently Asked

How is the CCT and wattage adjusted?

Built-in switches on the driver allow the CCT to be set to 3000K (warm white), 4000K (neutral white) or 5700K (daylight) and the wattage to be set to 23W or 33W. The settings are adjusted during installation and can be changed at any point without re-wiring.

Does it fit a standard ceiling grid?

Yes. The 595x595mm panel is designed to drop into standard 600x600mm modular ceiling grids used in commercial and institutional buildings. The 70mm depth sits within typical ceiling void spaces.

Is this panel dimmable?

No. The ELENA is a non-dimmable panel. For dimming control, specify a separate dimmable variant or use external building management systems that control via relay switching rather than dimmer circuits.

What does Tp(a) rating mean?

Tp(a) is the lowest stroboscopic visibility measure in BS EN IEC TR 61547-1, indicating that the panel can be used to an unlimited extent in general applications without causing perceptible flicker or stroboscopic effects under normal operating conditions.
