This blog is authored by Kevin L. Willmorth, owner of Lumenique, LLC and Tasca.

I have been involved in lighting application design and product development since 1981. This has included consulting businesses and executive positions with several lighting fixture manufacturers. I have been a regular presenter at trade conferences on topics including application approach, lighting technology, controls, and measurement techniques.

My company, Lumenique, LLC, is my design entity, now focused on creation of unique, sculptural quality side-table and task lighting, sold through my Tasca outlet.

The content in this blog is an open expression on topics, colored by lifelong interest in the arts, technology, hot rods, motorcycles, and just making things.

    Hi Kevin,

    I have a passion for SSL technology and working for Philips I am involved with this technology on a day to day basis both at a commercial and technical level.

    I am keen to discuss topics on this technology , electronics, new drivers , applications , shortcomings, critiques , chip level , optics , life times derating curves etc .

    Please let me know how can i participate in this unique opportunity.

    You can submit content to me through email, with small photos, graphics, or?? Consider writing short articles on where you see the technology going in practical terms, or how things are advancing in ways we should all be interested in.

  3. How about providing you with products for testing ?, no strings attached! we developed a complete line of SSL products with care for design and I would like to know how good they score in your tests

  4. Hi Kevin,

    Can you supply me with a shipping address?, kind of difficult to find it here online
    my personal e-mail is henri at bit dot com dot tw

    Thanks !

    As someone who reads most of the trades, and has back and forths with industry leaders
    as well as people like Randall Whitehead.I just stumbled on your wisdom. Your grasp of the
    lighting realities is extremely encouraging for me.I work both as a Mfg rep, Industry advocate, and energy loss analyst – ( It barely fits on my biz card) I will take you up on
    your offer regarding assessment of the fine products I use/ advocate.
    Kevin I would love to know your views on intelligent lighting. As the migration to quality SSL
    continues I see only failure for mfgs who are foisting 2007 era tech on the masses and
    identifying it as the latest and best.I’ve little patience regarding quality standards-I ‘m anxiously awaiting things like the “F” rating / CQS metric. On a different note– I would also like to know if you think Olets will leapfrog Oleds – Keep up the good work , SSLPro

      Thanks for the comments. I personally believe that until we engage in integrating intelligence features into SSL, it will be somewhat slow in implementation, as its costs and integration complexity will always be problematic. When you integrate intelligent features, the technology begins to set itself apart as value differentiated from all other light sources… which will inevitably lead to real transformation. The trick is zero-cost value added. Since all SSL products incorporate electronics to some degree, the cost of adding intelligent features is very small, compared to attempting to incorporate similar features into conventional sources, which as dumb light emitters with little effective response to micro control. I do believe that at some point OLETs will push OLED and low power LEDs aside. To have a logic circuit emit light directly will allow integration of intelligence at the cost of a SC transister… almost zero cost. Certainly for display and luminous panel emission, this has exciting potential. I am beginning to doubt whether OLED will actually overcome its problems of life, output, efficiency, and consistency. Seems these issues are very persistent and difficult to resolve at a level that will satisfy general illumination needs. Display may one day be widespread, but for high output levels… the time to market may be so long that other technologies, like OLET, walk by it eventually.

  7. Hello Kevin

    I am a Lighting professional and keenly follow the developments in LED as this is going to be our future light source. I was impressed by your post on power factor. If the pf realization is ignored by the manufacturers while specifying their products the consumers will be taken for a ride like they have been taken in case of CFL.I have a blog site or where I have been focusing on LED. I would appreciate if you care to go through it and send in your invaluable suggestions and contributions on developments in LED.

    I am impressed with your comments. I have, from my father an appreciation of architecture and some of his equipment. But my real question is about the GE DW-48 light meter. I just found one in a local camera shop and got it. But now I search for a source of manual. You got yours from your father but have you seen any copies out there? Thanks, Jerry
