LIGHT + BUILDING / LED REVIEW


a traditional clear bulb. Not only does the lamp look like an in- candescent bulb when illuminated but its dimming capabilities were excellent and I would be sure that most people would prefer these types of products compared to remote phosphor or standard diffused type LED bulb retrofits. As the LED source is placed remotely from the LED driver the lifetime of the product will definitely be longer than most LED bulbs in the market today.


What will happen by the next Light + Building? Of course it is always risky to predict what will happen in the next two years, but I think we will see the following at the next Light + Building: • T5’s will be completely replaced by LEDs in terms of new fixtures as well as high ef- ficacy retrofits. • LED prices will have decreased by over 50% and maybe as high as 70% compared to this time meaning the return on investment compared to traditional light sources for most applications will be between one and two years. • OLEDs will be a serious player in the general lighting market and costs will have tumbled from today. • LED fixtures will actually be able to dim properly (most of the products on show were very poor with either a poor dimming range and/or flickering of the LEDs at low intensities) • Samsung, LG and the major Japanese electronics companies will be significant players in Europe as they use innovation, improved products and competitive pricing to break down barriers unlike in the last two to three decades. • Standard white PC LED efficacies will reach 180lm/W in production. • Variable CCT products will be prevalent, low cost and internet enabled. That’s all for now but if you would like to contact me to discuss any lighting topics then email me or connect to me on LinkedIn.
