Illumination in Focus top 20 stories of 2014: Lamps dominate reader statistics
While LED-based integral luminaires will likely prove to be the most significant LED lighting products long term, our 2014 viewing patterns suggest more interest in retrofit lamps for now.
Year end is clearly in sight, and that means that it is time to look at the most trafficked of our posted articles for 2014. Again we offer our top 20 articles based on your interest as determined by page views, and 2014 reveals that LED-based retrofit lamps are of greatest interest despite the limitations of the bulb or tube form factor. Still, we’d expect innovative luminaires to become predominant not too far down the road, and we had a good representation of different types of solid-state lighting (SSL) projects on the list as well.
Retrofit lamps were even more prevalent than on our top 20 list that we posted a year ago. Indeed, this year the lamps occupied one third of the list.
Last year, however, price was the most common theme in lamps stories. This year light quality is far more important. For instance, several stories were focused on high CRI products including the Cree announcement of new MR16 lamps. Likewise, Soraa focused on quality in its directional lamps. We saw the beginnings of the quality story emerge in the top 20 list last year.
If you want a quick look at what was hot during the year, look no further than the lighting roundtable that we published in conjunction with The LED Show 2014. Lighting executives shared their views on key developments in areas such as dimming, tunable lighting, and controls.
Looking back, it's fair to ask what disappointed in 2014. In last year's top 20 article, we speculated that we would see far more tunable lighting products emerge — both tunable white point and color. To some degree, the tunable trend is happening but not as fast as we would have guessed. It can become one of our expected trends for 2015.
That leaves us with our holiday wishes. Top on the list would be the industry-wide acceptance of a ubiquitous lighting network technology. Networks and controls are happening — but a little at a time and often in a proprietary manner. Here's hoping for better in 2015, but for now enjoy the 2014 list.
