Money does not buy happiness.
We’ve heard it before, and it is a compelling sentiment. Unfortunately, it is all too easy to assume that the basic needs of sustenance, shelter, security and comfort are a given. These cost money. Without food, protection from the elements, security from harm, and a modest degree of comfort, even a basic level of happiness is not possible. We live in a world (more…)
For those who attend my presentation on Metering and Meter use at the LED Specifier Summit this Tuesday (9:00AM) here is the related reference information and a copy of handouts for the presentation. Let me know what you think and post your comments or questions here. If you have any questions or wish to discuss this presentation or have a metering issue you’d like some help with, let me know.

I have several fresh and brewing ideas about office lighting, putting new technology to work to make sitting in our little prisons more enjoyable and healthful. To put these ideas in context, and to consider real-world application nuance and detail, I’m collecting images of actual office spaces from anyone will to share. I don’t need great pictures, just a quick snap with a phone that shows as much of the space as possible, perhaps with the lighting visible.
My office also houses the 3D printers. They need the clean/warm space to work best, and I like having them close.
If you have a moment, include any comment you might have about what you hate about the space, and the lighting, and perhaps what you like most? The spaces don’t have to be all cleaned up and tidy, in fact, the mess tells me as much as the arrangement.
I promise the images will go no further than a folder on my hard drive for reference in creating illustrations of model spaces within which I will be laying out alternative approaches and lighting products that might be applied.
You can do this all in less than a minute with a smart phone by sending me a an image to 414-241-5124, or kwillmorth@lumeniuque.com. I’ll send you a look in the future to what came from the effort, giving anyone who participates an inside peak of what I came up with and why.
Thanks in advance to all that participate!
We’ve been working for several months on an LED Color Viewer that is easy to use, affordable and portable for use in the office and for taking it to client offices. Well, we’ve finished it at last.
The viewer contains 5 Cree CXB COB LEDs in 2700K, 3000K, 3500K, 4000K, and 5000K, each rated at 90CRI, that are selected with a simple selector switch. The viewer also includes a dimmer, so you can see the effect of light level on color. A rocker switch allows the light to be turned on and off without disturbing selector/dim settings. The viewer is easily folded up for storage and transport in an included carry case, which is padded, and includes room for the cord, as well as a pocket for taking along various color cards. It’s a perfect companion for the samples room, as well as viewing print media by graphic designers, and study by lighting designers when making presentations to customers.
The Lumenique main web site has been completely refreshed and revised to create a cleaner appearance that is easy to walk through. The original site was created (read evolved) over a period of 20 years, from its first appearance in 1995. The content was built up over that time to include a wide range of topics, from lighting and art, to BMW tuning mods and go-karts and our SCCA racing endeavors. That was before the days of blogs taking over that sort of activity. The new site is more focused and directed at our core business interests and competencies – and no longer requires a gamer’s commitment to navigating twists and turns to get an idea of who and what we are. The Lumenique Product Center has also been freshened up to match the new graphic design. (more…)
Solid-state lighting presents many opportunities to create fidelity in specification of lighting not practical or available before. Further, the blend of aggressive marketing, hype, and deception on the part of solid-state product manufacturers demands more diligent specification than ever before. The days of the conventional mode of specifying luminaires and lamps as two separate components, with experiential trust in both, is over. Today, luminaires and light sources are integral to one another, often offered up by those who have marginal experience, and a strong desire to realize sales. The only defense against predatory and overly aggressive marketing is to understand and develop a strong specification foundation. The next protective barrier is to hold that specification. The following are suggestions for building a solid-state lighting foundation for any luminaire specification, with rationalization for each consideration in practical terms. (more…)
After reviewing a range of different metering choices in actual use, I compiled a summary of findings, as well as my own personal subjective ratings of features and overall utility as a lighting professional. This chart is the collection of all findings in a simple comparison table for those who find this useful (like me): (more…)
