Independent Research using Xicato Spot Modules: Link Between Light Quality and the Attraction of Retail Displays
Independent Research using Xicato Spot Modules: Link Between Light Quality and the Attraction of Retail Displays There is a strong link between the quality of accent light sources, in terms of color rendering ability and in particular the rendering of deep reds, and the attention-grabbing potential of retail displays, according to the outcome of an on-site evaluation by end-users and lighting designers conducted by independent researcher, Colette Knight and peer reviewed by University College London. Shoppers and lighting designers took part in the experiment carried out in a House of Fraser store in London. It showed that there was no statistical difference between the appreciation of colors rendered with halogen or Ra 95 (R9 >95) LED sources, whereas the rating was lower for Ra 80 (R9<20) LED sources. This translated directly into the rating of the display itself in terms of its attraction. Read more »

UCI Researchers Find LED Products Billed as Eco-Friendly Contain Toxic Metals
LED products usually are electronic products that should be handled as electronics scrap if disposed, anyway. A realease of potentially hazardous substances under regular use is very unlikely, even when broken. LED professional does not agree with the generalized conclusions of this research. However, it is important to challange statements of PR and lobbies to boost more eco-friendly products. In fact, light-emitting diodes of tested holiday bulbs, traffic lights and car beams marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.
