Highlights of DOE Solid State Lighting R&D Conference

Shonika Vijay 02/09/2015

Recently, we had the DOE R&D conference in San Francisco. As always, it was a great event as the key industry players and decision makers came under one roof. I wanted to share some of my highlights and experiences from the event. Before that, one of the treats for me was looking at the new Bay Bridge from the shores of Treasure Island. Though I am a Bay Area resident, I regret that I hadn’t done this before—I usually just drive through it. The Bay Bridge looked magnificent, as it wore jewels of LED lights. The directionality of the lights was brilliant and it limited light spillage into the bay. So thank you, DOE, for allowing me this experience.

What does LG Chem's "5 lm/$" really mean for lighting?

Stephanie Pruitt 02/05/2015

LG Chem came out this week claiming to have the world’s highest OLED lumen-price ratio at 5 lm/$, but what does this really mean, and how does it compare to traditional and LED lighting?

To really see how this ground breaking development in OLED lighting compares, I have listed below the average selling prices (ASPs) for the general lighting luminaire form factors that Strategies Unlimited believes OLEDs can potentially penetrate: downlights, troffers, and suspended pendants (we do not believe OLEDs will play in track lighting, high bay, or street lighting due to current lumen output, efficacy, and price).

LED COB is Coming

Martin Shih 01/26/2015

We have now released our latest market research report, The World Market for COB LEDs in General Lightingwhich covers the market for LED COBs and Multichip Array COBs. We forecast the overall market for these COBs will grow significantly to $4.35 billion in 2020 from $1.54 billion in 2014. In addition, the report indicates that the market will grow by 40% YoY in 2015. The long term growth is mainly due to the increased penetration of COB luminaires and lamps into some specific lighting applications, such as downlights and spotlights. With better light distribution and design flexibility, we expect a significant growth for COB, especially in directional lighting applications.

Revolution vs. Evolution

Philip Smallwood 01/22/2015

At the 2014 Strategies in Light Europe conference, there was one recurring theme that I thought was very interesting: evolution vs. revolution. I think it is very important for people in the lighting industry to understand that LEDs in themselves are not a revolutionary (disruptive) technology that is changing the industry, but rather a natural evolutionary progression of light emitting materials/methods to create usable light. As presented by Dr. Thomas Knoop, the Managing Director of INTEGRATED, a technology is disruptive in an industry when it attacks the market by offering a different value driver (usually convenience or price) and not when it just fulfills the need of the average customer. The two charts provided below are visualizations of these ideas. 

Lighting Industry: 2014 in Review and What to Expect Next

Shonika Vijay 01/19/2015

As the year 2014 recently ended, I thought now would be a good time to review what the lighting industry has gone through along with what lighting trends we anticipate in the near future. 2014 was an amazing year for LED lighting. Here a few recent key things that LED lighting experienced in 2014:

The Early Peak Effect in the photonics market

By Tom Hausken
Our new market report highlights something I call the “early peak” effect that appears a lot in capital equipment sales, including many laser products. It’s what happens when you sell some lasers into a new application, and then sales drop off when the customers have installed all the lasers they need. It’s so typical of the micro materials processing market that I have come to include it in some forecasts.

Here are the phases:
· Rollout of lasers for a new application
· The early peak in sales
· Saturation of the installed base
· Early wearout and upgrades
· A second “baby boomlet” as replacements for wearouts peak


If you don’t account for the early peak effect, you can overestimate laser sales by assuming that sales continue at peak levels, year after year. The news of new applications have surprisingly wide reach and long tails, feeding the perception that sales are higher than they really are, especially if the application is really cool, like stent cutting.

What keeps the market going is that there are new applications launched on a regular basis that smoothes out the overall growth in the market. But, sales any particular company can be very choppy. And, the mix of products grows more diverse with every new application in the market.


A laser salesperson will recognize the early peak effect, but it gets lost when you look at overall market numbers. It’s not hard to explain to the old-timers in the business, but it doesn’t have a ready label, as far as I know. I couldn’t come up with a better name for it, so for now it’s the “early peak effect.” If you want to call it the “Hausken effect,” that’s fine with me, too.
