Specific Technical Data

Mechanical Dimensions

The 280 × 60 mm module uses a standardized 3×11 footprint with clearly defined LED, terminal and mounting positions. M3 flat-head screws provide secure heat-sink attachment, while the aluminum-PCB construction supports efficient thermal transfer and straightforward luminaire integration.

Electrical Design & Installation

The 33-LED circuit is designed for constant-current operation at 350 mA with a nominal forward voltage of 66 V. Use a suitable LED driver with short-circuit, overload, over-temperature and application-appropriate surge protection. Constant-voltage operation may cause irreversible module damage.

For optimum balance between cooling requirements, light output and lifetime, the tp reference temperature should be maintained at 85 °C. The datasheet specifies Rth, hs-a 2.31 K/W and a reference cooling area of 168 cm² under reference conditions.

Optical Variants

Four representative CCT and CRI configurations illustrate the LED source's controlled chromaticity and spectral performance. Each option maintains typical colour consistency within 3 SDCM while addressing different visual and application requirements.

2700 K Optical Performance

2700 K | CRI 95 | Typical colour consistency ≤3 SDCM

The 2700 K configuration uses a nominal chromaticity centre of x = 0.458, y = 0.410. Its warm spectral profile and CRI 95 performance support comfortable, visually rich illumination where faithful colour appearance is a priority.

3000 K Optical Performance

3000 K | CRI 90 | Typical colour consistency ≤3 SDCM

The 3000 K configuration uses a nominal chromaticity centre of x = 0.440, y = 0.403. This warm-white option combines CRI 90 colour quality with controlled chromaticity for architectural, area and pedestrian-oriented lighting.

4000 K Optical Performance

4000 K | CRI 85 | Typical colour consistency ≤3 SDCM

The 4000 K configuration uses a nominal chromaticity centre of x = 0.4339, y = 0.4032. The neutral-white spectrum and CRI 85 performance support clear visibility in street, area and industrial applications.

6000 K Optical Performance

6000 K | CRI 80 | Typical colour consistency ≤3 SDCM

The 6000 K configuration uses a nominal chromaticity centre of x = 0.321, y = 0.336. The cool-white spectral distribution and CRI 80 performance provide a crisp visual impression for roadway and industrial lighting.

Engineered for Long-Term Lighting Performance

The BrightLX 3×11 LED Module combines output options from 2,858-3,312 lm, efficacy up to 144 lm/W and broad colour-temperature availability in a compact 280 × 60 mm platform engineered for reliable outdoor operation.

With 350 mA constant-current operation, a nominal 66 V forward-voltage platform, controlled colour consistency and compatibility with IP6x secondary lenses, the 3×11 module provides a practical foundation for efficient street, area, flood, high-bay and industrial luminaires.
