“In addition to upgraded performance across the existing portfolio, Lumileds has introduced 4,000K and 5,700K emitters in the 90 CRI range to address needs in stadium and museum lighting,” said the firm.

Un-domed emitters allow smaller diameter optics to be used for the same beam width compared with domed optics – ‘more punch’ as the marketeers are apt to say, although overall efficacy is reduced.

Also, without a dome the package can be smaller, allowing higher packing density.

According to the firm it is suited to “applications requiring tight beam angles such as spotlights, down-lights, retrofit lamps and street lights”.

Colour binning is interesting, with 5, 3 and the “first-ever”, claims Lumileds, 1 step MacAdam Ellipse options.

CRIs of 70, 80 and 90 CRI are now available.
