Discover our new Spectra table lamp ! Part of our new GEMLED product range, the Spectra is fitted with a new “utra-thin” heat dissipater. It is very light, flexible and adjustable in height. But what makes the Spectra so special is both its CRI of 92% and a new LED technology, which provides a great light rendering on both warm and cold types of coloured gemstones, without any light colour temperature variation required.
