New Casambi-Enabled LED Drivers from Harvard

Casambi provides a modern wireless lighting control system based on Bluetooth Low Energy, the only low power wireless technology in all modern smart phones, tablets and even smart watches. Working with Holders, Harvard Power Systems have integrated a Casambi node into its full range of CoolLED PRO CLi Series LED drivers whilst retaining all their high specification features in their ultra-compact size – the drivers are half the size of other lower technology drivers. The key advantage of the smaller case size of Harvard LED drivers is that they fit through relatively small 40 mm or 56 mm holes in the ceiling, making them ideal as a fast-fit solution for use with LED downlights.

The CoolLED PRO CLi Series of Casambi-enabled LED drivers are available in 15W, 25W and 40W versions and are programmable from 100 to 1400mA. Specification rich, the CLi Series LED drivers provide smooth flicker-free dimming down to 0.1%, particularly desirable for aesthetic & display applications, whilst also allowing smooth Soft-On & Soft-Off functionality, offering enhanced comfort for interior and architectural applications.

Mark Needham, Managing Director of Harvard Power Systems comments, " We are delighted to have worked in partnership with Holders on this range of Casambi-enabled drivers particularly because we know that customers will be assured of the best possible customer service in the way of technical support and advice to achieve the best solutions for their lighting schemes."

Mat Hanson, Sales Director for Holders, adds, "Holders are delighted to partner Harvard Power Systems in promoting their market leading, integrated Casambi LED drivers. This great development marries best-in-class Bluetooth technology, in the form of Casambi, with the deepest dimming, flicker-free technology from Harvard. Bringing together these two exciting technologies, the Casambi-enabled Harvard CLi15 and CLi40 LED drivers are ideal for the demanding specifications of residential, architectural, hospitality and retail projects where exciting dynamic control of LED lighting is required, without compromising the quality of light being delivered."

Harvard's CLi Series LED drivers including 0–10V, DALI dimmable and now the fully embedded CASAMBI variants, all come with a comprehensive five-year warranty. All are SELV compliant and will operate with a lower voltage supply, compatible with emergency applications. Extended life tests demonstrate high reliability and low audible noise below 20dBA yet despite their high specification, these new LED drivers are competitively priced to meet market demand.
