Digital Lumens

First look – our Enterprise LED Lighting Report

Tomorrow we’re announcing the publication of our research report Enterprise LED Lighting, distributed with our partners at GreentechMedia.

As we did with our Enterprise Carbon Accounting research we conducted interviews with all the relevant players in the emerging industry – in this case it included DOE engineers, utility managers, vendors, and most importantly, our commercial and industrial customers.

The need for this report became apparent as we were launching  Digital Lumens, a spin out company from Groom Energy who announced their business this past May.  At the time it was clear the commercial and industrial LED market was going to surge over the coming years and there was very limited market data studying  customer’s needs relative to the newest products being introduced.

Once we started building the report it became clear we could answer some important questions:

  • Market: How big is the market today and how fast is it growing?
  • Applications: which applications are best suited for LEDs today versus in the future?
  • Customers: why are early customers buying products today and what are they learning?
  • Technology: How are LED systems designed? What are the key technical challenges?
  • The Vendors: Who are the players in the market and which products are they offering?  (this we addressed through our LED Market Players Guide profiling 50+ vendors)

The key drivers for market growth we identified were:

  1. Recent LED chip performance advancements which allow more cost effective
    designs for replacing existing lighting systems;
  2. Newly introduced utility energy efficiency financial incentives for converting to
    these LED-based systems;
  3. Increased interest from building owners in applying sustainably oriented lighting
    retrofits that save money for their operations.

The study took longer to complete than we originally anticipated – partly because we underestimated the amount of work – and partly because things in the LED market have been changing so quickly, even while we were compiling our research.

By 2009 we’d compiled a list of @ 100 vendors who were shipping commercial and industrial general illumination LED fixtures – today our list is at 250+ and still going (and more will come out of the woodwork now that we’ve published our list.)  When we started there were only “custom” utility rebates and virtually no prescriptive rebates for LED based retrofits.  Today, many of the leading utilities have prescriptive schedules for LED PAR, MR, High Bay and Low Bay upgrades.  Meaning the customer market is accelerating and this is driving the utilities to react.

So, I’m assuming by next week we’ll already be developing our first update to the report :)

    Digital Lumens’ first LED customer installs

    Now that Digital Lumens (DL) is out of stealth mode it makes sense for us to start covering some of our learnings with LED high wattage applications.

    Beginning last year we conducted a series of DL test trials with our customers.  Recently we exhibited at the IARW show as a “coming out” party, showing both the now shipping DL system and a short video from our first large installation at a yet-to-be-announced freezer cold storage facility.

    Prior to our DL tests we had learned that operating managers had three general concerns about LED high wattage applications – (1) light level performance, (2) cost and (3) glare.

      Digital Lumens – congrats on DOE award!

      Digital Lumens new LED fixture

      In 2006 Groom Energy engineers began testing the latest general illumination LED fixtures with our early adopter customers.  Our demonstrations proved that these products were still too expensive, couldn’t produce enough foot-candles and had no track record to support their 100,000 hour operating life claims.  More importantly, none of the them took advantage of what LEDs do best – intelligent control.

      These early LED systems, designed by traditional HIF/HID lighting engineers, were burdened with bad design DNA.  Their designers literally shape reflective metal around lamps and ballasts from GE, Philips and Sylvania, not layout circuit boards for a solid state lighting systems.  Even the most basic HIF/HID control features need to come from third party companies.

      High performance, intelligent LED systems require an interdisciplinary design team who can optimize the entire system, simultaneously considering  optics, thermal, mechanics, power and control.  It’s more like designing a computer than metal bending.  No team like that existed.

      So in 2007 Groom Energy set out to do this ourselves.

      We recruited a small world class team into a separate company, initially calling it GroomLED, co-locating the team in our Salem office (later we renamed it Digital Lumens.)  Our goal was to develop LED based lighting systems for high wattage applications in our customer’s commercial and industrial environments.  We took the DL team on the road with our customers, confirming product requirements with each of them.

      Our friends at Flybridge Capital took the risk with us, providing the initial seed venture capital in order to test the company idea.  Since then the press has unconfirmed reports noting two follow-on DL venture capital fundings, one with Flybridge and Stata Ventures in May 2009 and a second with Black Coral Capital in December 2009.

      Although DL continues to operate in stealth mode, we were excited this past week when DL was awarded a prize at a Next Generation Luminaires Solid State Lighting Design Competition, jointly sponsored by the Department of Energy SLL Lab , IESNA and IALD.

      Stay tuned – there will be more DL announcements over the coming months, but at this point we wanted to give props to DL and answer the inbound questions we’ve been receiving…
