Flicker is a persistent and frustrating issue, and has been since the first fluorescent and HID lamps were put in service. Complaints of headache, migraine, feelings of ill health, and eye strain are the most common complaints. For some, flicker at 100Hz (Europe/Asia) or 120Hz (North America) is debilitating. Studies have shown that flicker creates reading errors from rapid eye movement changes under sources flickering at under 200Hz – NCBI The effects of flicker on eye movement control, Energy Focus Presentation ‘Lighting Flicker: Effects of Flicker in the Classroom’, including roadway effects – Lux ‘Street light flicker is a new hazard, says watchdog’, CBC – ‘Calgary seizure sufferer worries flickering LED street light will break down again‘.

I will not go into a great deal of detail here on the effects of flicker on human health or the environment. There are hundreds of articles on this topic, by experts in human (more…)

According to marketers of Twitter, Facebook, LinkedIn, Instagram, et al, social media is the engine of change, the foundation for bringing information and real transformation to the people. With Social Media, we will see the world connected and refreshed through the voices of the previously unheard. Social Media is the new light, the symbol of freedom and ultimate new world order founded on the concrete foundation of the first amendment, the true voice of “the People”. It has enabled revolution and advanced the human cause. It all sounds so… amazing and spectacular, if not completely incredible.

Behind the scenes, social media is actually just a software/app product that generates (more…)

Before we get into this topic, let’s remember that history is filled to overflowing with cries of lighting technology destroying human health. When the incandescent lamp emerged, the gas light industry flooded the market with baloney about its harmful effects (including claims that electric lights caused women to get the vapors), in support of the healthful glow of gas lighting (gag). Fluorescent and HID technologies have been under attack from their very first introduction. It’s quite funny to see now the defense of HPS by LED detractors, as it has been the target for criticism for decades. My advise for the apoplectic LED detractors… take a very deep breath and get over it. Every light source carries with it a compromise, including daylight, with undesirable effects we must do our best to mitigate. I suggest to anyone interested in the processes of new lighting technology: An interesting read on the 60 years it took to get lighting off the gas. That said… (more…)

I’ve posted this sort of content before and will do so again. This is the sort of thing I cobble together from found objects, spare parts, experiments in fabrication, and other brain re-setting exercises.

Follow your passion and success will follow you

I find these “inspirational” vivications irritating and shallow. At the risk of being pedantic, allow me to explain.

In this case, the words evoke images of everyone loving what they do, and succeeding for it – with the inference of success pointing  to fame and fortune. Certainly, if you look at successful people in the public eye; actors, musicians, athletes, motor sports champions, internet and social media innovators, software developers, wealthy investors, etc…, they (more…)

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…)

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.

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!

 

LED Color Viewer

Posted: August 10, 2016 in Uncategorized

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.

viewer-on

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…)
