Lumileds LED arrays up to 6000Lumileds has announced Luxeon CoB, chip-on-board LED arrays up to 6,000 lm with versions with illuminated diameters of 9, 13 or 15 mm.

Colour temp is 3,000K, states Lumileds, with 105 lm/W efficacy and CRI >80; all at 36V nominal forward drop. Versions are are hot tested and specified at 85°C, and are based on metal-core printed circuit boards (MCPCBs).

There are four versions, with typical light outputs of 1,150 (9mm), 1,725 (13mm), 2,300 (13mm) and 3,450 lm (15mm) at 300, 450, 600 and 900mA respectively.

Possible applications? Spotlights, down lights, and replacement of directional incandescents (PAR/AR111, for example).
