Lumileds to show Luxeon R for street and industrial lighting

Lumileds has launched Luxeon R, a lighting LED designed for outdoor and industrial applications such as streetlights, high-bay lights, wall packs and bollards, writes Steve Bush.

For these uses, the colour rendering/efficacy trade-off is set in favour of efficacy, although minimum colouring index is still 70.

The devices are manufactured such that binning is not required.

SDCM (standard deviation colour matching) is <5 – good enough for outdoor and industrial use, though differences could be noticed in consumer or office lighting.

The LEDs are tested and specified at 85°C, minimum flux is 160-200 lm, and colour temperatures of 3,000, 4,000, 5,000, 5,700 and 6,500K are available.

Typical efficacy is 128 lm/W, except in 3,000K and 4,000K versions which are 105 and 125 lm/W respectively.

Luxeon R is available now and will be shown at Lightfair International in Las Vegas in May.
