The Sensor LED Back-Lit Panel 62x62 cm with microwave sensor beneath the diffuser is designed specifically for European ceiling grids (620 × 620 mm). Motion detection is completely contact-free through the diffuser – no visible sensor eye, no drill hole. 28 W, 4,200 lumens, 150 lm/W with Lifud branded driver and 1–10 V dimming. The colour temperature is freely selectable: 3000 K (Warm White), 4000 K (Neutral White) or 6000 K (Cool White) ? please select when ordering. The intelligent sensor programming can be adapted to different situations ? easily and quickly changeable at any time via the remote control, even retroactively.

The Highlight

Invisible Microwave Sensor Beneath the Diffuser Plate

Unlike conventional PIR sensors with a visible sensor eye, the microwave sensor of this panel sits completely behind the diffuser. Motion detection works via high-frequency radar signals that pass through the polystyrene diffuser layer ? no visible opening, no sensor eye, no compromise on the pure panel aesthetic.

Technology

Microwave radar (5.8 GHz)

Detection Range

360° around the panel

Intelligent Lighting

Through programmable sensor

Important Note

The sensor settings (hold time, standby brightness, daylight threshold, detection range, etc.) are configured via a separately available radio remote control. The remote control is NOT included and can be ordered as an optional accessory.

Sensor Configuration

Remote Control Functions (Optional)

With the separately available remote control, all sensor parameters can be individually adjusted. Simply aim it at the panel and press the desired button ? the panel acknowledges the change with a brief blink.

Hold Time Hold Time Duration the panel stays at full brightness after the last detected motion. Adjustable in steps from a few seconds to several minutes.	Standby Duration Standby Time Duration the panel remains at standby brightness after hold time ends, before switching off completely.
Standby Brightness Standby Dim Level Brightness level the panel maintains after the hold time. Adjustable from 10% to 50% or full switch-off.	Daylight Threshold Daylight Sensor Lux threshold above which the panel will not switch on even when motion is detected ? saves energy when sufficient daylight is present.
Detection Range Detection Range Sensor sensitivity/range adjustable from 25% to 100% ? ideal for adapting to different room sizes and ceiling heights.	Manual Mode Manual ON/OFF / Dimming The panel can also be switched on/off manually and continuously dimmed (1?10 V / PWM). The sensor function can be temporarily disabled.
Power Levels (DIP Switch) Power Adjustable ? not via remote control Seven power levels available: 28 W (0.70 A) · 32 W (0.80 A) · 34 W (0.85 A) · 36 W (0.90 A) · 38 W (0.95 A) · 40 W (1.00 A) · 42 W (1.05 A). Important: Power levels are NOT set via the remote control but directly on the driver via DIP switch. The remote control exclusively configures the dim level and the sensor parameters.

? Note: The remote control is available as an optional accessory and is not included with this panel. A single remote control can configure multiple panels simultaneously.

Your Benefits

Why This Sensor Panel?

EYE

Invisible Sensor

The microwave sensor sits hidden beneath the diffuser ? no visible sensor optics, no drill hole, no visual disruption of the panel design. Ideal for refined architecture and office design.

Microwave Technology

High-frequency radar (5.8 GHz) detects motion reliably ? through the diffuser and even partially through thin materials such as plasterboard or glass. Significantly more precise than PIR sensors, with no temperature or light influence.

LIFUD

Lifud LED Driver

Lifud is one of the world's leading LED driver manufacturers. Power factor =0.95, flicker-free constant current technology and 1?10 V / PWM dimming for maximum compatibility.

lm/W

150 lm/W Efficacy

4,200 lumens from just 28 watts ? a system efficacy of 150 lm/W. Combined with the sensor, actual energy consumption is further significantly reduced.

DIM

DIP Switch Power & Dimmable

Seven power levels selectable via DIP switch on the driver (28–42 W). Additionally, the panel can be continuously dimmed via the remote control and sensor programming – perfect for daylight-responsive lighting control.

UGR<22

Glare-Free with 120° Beam

Texture PS diffuser plate ensures uniform light distribution across 120° with UGR

Back-Lit Technology

Why Back-Lit Beats Edge-Lit

Unlike budget edge-lit panels, where LEDs sit only at the edge and the light has to be redirected via a reflector plate, in back-lit panels the LEDs are evenly distributed behind the diffuser ? directly across the entire illuminated surface. The result: noticeably more homogeneous light, higher efficacy and no visible hotspots or dark zones.

Uniform Light Distribution LEDs across the entire diffuser area ? no visible LED dots, no stripe patterns, no edge hotspots like with edge-lit panels.	Higher Efficacy Lower light losses from reflection paths ? light is no longer fed in sideways and redirected, but radiates directly downwards.
Better Heat Dissipation LEDs are spread across the entire back side ? heat is distributed over a larger area, extending LED lifespan.	Longer Lifespan Due to lower thermal stress on individual LEDs, a back-lit panel typically achieves a significantly higher rated lifespan than a comparable edge-lit panel.

FAQ

Frequently Asked Questions

Does the panel work without the remote control?

Yes ? the panel comes with pre-set sensor parameters (typically: 60 sec hold time, 100% sensitivity, no daylight limit). For individual adjustments or to activate standby and daylight functions, the optional remote control is required.

How exactly does a microwave sensor work?

The sensor emits high-frequency radio waves (5.8 GHz) and measures changes in reflection. When a person or object moves within the detection range, the reflection pattern changes ? and the panel switches on. Unlike PIR sensors, no heat radiation is measured, so detection is independent of temperature or clothing.

Can one remote control multiple panels?

Yes ? a single remote control can configure all panels within range simultaneously. For larger installations, one remote per floor is typically sufficient, as the settings are stored in each panel.

What is the difference between back-lit and edge-lit panels?

In back-lit panels, the LEDs are evenly distributed behind the diffuser ? resulting in more uniform light distribution, higher efficacy and fewer hotspots compared with edge-lit panels, where LEDs sit only at the edge. Back-lit is the higher-quality technology.

Which colour temperatures are available?

The panel is available in three colour temperatures: 3000 K (warm white) for hotels and residential areas, 4000 K (neutral white) as universal office lighting, and 6000 K (cool white) for shift operations and areas requiring increased concentration. Please select when ordering.
