Return to Passion

Lumenique was created in 1986 as part of my Lighting Design Consulting practice in Las Vegas. Originally, it was intended to be a design studio, where I could create unique items for customers, including art galleries. I even had dreams of it being a showroom of custom lighting creations. The name itself was a creation of mine, and reflects the intent fully:

Lumen (Light) + Unique (of special character) = Lumenique

Over the years, as I got busy with life, and from a lack of focus (and abundance of youth), I let this evolve into a wide range of activities and offerings, including artwork, performance components for BMWs, and consulting services from product development to UV curing. Lumenique was first put on the internet with a rudimentary web site in 1995, primarily for sharing information, and at times collected dust as I focused elsewhere. Over the 35 year journey, the origins of Lumenique were muddied by active career life that distracted me from where I intended it to go.

That ends now.

New Focus

On November 1, 2020, Lumenique has returned to its origins, and my sole focus going forward. I will be creating and offering artistic portable lighting products of unique artistic quality, inspired by architecture and machines.

New Web Site

The Lumenique web site has already been rebuilt to reflect this new direction.

Link to the New Web Site as of November 6

The new site will evolve as products are added, and we finish the storefront components. In the meantime, I have created an archive gallery with historic designs, and a ready reference guide to the 52 in 52 project, so a visit now will provide an insight into where I started.

The String of Light

The lighting industry is a faceted and muti-layered universe. However, the bond that holds it all together is that lighting exists only to serve human kind. To the consternation of technologists and engineers behind the SSL revolution, humans (other than those in the are in the business of engineering and technology) are not particularly concerned with metrics, formulas, or objective measurement. Humans are emotional animals, that respond to light and shadow, who feel before they see, and absorb what they see as real, even when it isn’t. To this end, artistry in light remains a strong factor in the human condition, even when those experiencing it are unable to express its influence, or even acknowledge its impact. This underlying reality is what causes so many metrics addicts to go mad, as they attempt to quantify and control a market that is in fact, uncontrollable. The illusion of control is the fallacious reality we live in as humans. We cannot express our needs for an emotionally, soul energizing, comfortable or pleasing existence in metric terms. (more…)

Looking for Delight-able Customers

Solid-state lighting technology is poised to cause an explosion of artistic lighting design that eclipses all before it. The opportunities to do great things is limitless, with a great many interesting applications have already come from utilizing it to great effect. LEDs and OLEDs open doors to creative work like nothing before them. While the technologists focus on saving energy and other metrics to satisfy any number of codes, comply with regulations and meet objective demands – artists are now finding ways to apply the technology to delight customers. This is what keeps me interested in this industry.

Background

My background in graphic arts was founded on a deep desire to delight people with creative work. As NCOIC of Graphics on Anderson Air Force Base, Guam,  I included art in otherwise mundane officious graphic presentations. There was a level of thrill when, as a lowly sergeant, a starred-up General seeks to you out to express his delight with a presentation.

The move from graphics to lighting design 36 years ago was fueled by the same desire to realize delighted customer response. Architects, Interior Designers and property owners, from home owners to casino operators, were the new delight-able generals to me. The addition of product design and development followed delight-able customers in manufacturing, coupling my design interests with my passion for making things with my hands. I’ve invested the last 11 years in solid-state technology in lighting for one reason – I see it as a new frontier in creating applications and products that delight customers. (more…)

No Magic Formula for Quality Lighting

In the discussion of lighting quality, there appears to be a desire to see a simplistic set of performance factors to be met, that can be universally pointed to as “quality”. This is most apparent from fixture manufacturers, who wish to have a set of 3-5 reductive bullet points to indicate their product is a “quality” product. Color rendering is one such factor frequently singled out in this effort, regardless of its relevance to an application.  A quality lighting system is more than the sum of products lumped together into a specification, each defined as quality components, without contextual inter-connectivity. Lighting quality is the result of creating a recipe of approaches, priorities and understanding/agreement that delivers a system that satisfies the end-user occupants, the facility operator, and external influences  to the highest practical level. To this end, I have attempted below to summarize, in the most reduced form possible, the systematic factors that define a quality design.

So, this isn’t at all about lighting, or solid-state, or technology. It’s just a gadget cat toy we call the Cat-apult.

08285I have a fondness for the halogen lamp. From the little 20W bi-pin 12V burners to the 500W double ended monsters, the combination of light quality, simplicity, toughness, light density and versatility filled a special place in the hearts of lighting designers for decades. While there were also  larger iterations of the technology reaching 20,000W, even the most halogen crazed found them to be a bit over the top, setting them aside for special applications. In my own experience, the 20W through 75W 12V burners, 15W through 65W MR16, 35 through 50W PAR36 and 75W through 250W mini-can line voltage lamps hit the spot for a wide range of focused and unfocused lighting product designs. For my personal portable lamp works, the low voltage burners, MR16 and the PAR36 lamps were my favorites. I could create live-structures (where the fixture acted as conductor) using remote 12V power supplies, allowing sculptures to be simple to the extreme.

This simple bridge design was created using building and armature wire, a PAR36 halogen lamp, and a ball bearing counter weight.

When LEDs arrived on the scene in the late 1990’s, I caught a glimmer of what was to come. By the year 2002, it was obvious that solid-state would be delivering something new, and that the properties of the source technology shared a great deal with the halogen lamp from a lighting perspective, with a huge advantage – far less heat, much tougher and resistant to impact, and very long lived. The only issue was, color quality was initially poor, consistency from LED to LED was awful, and light output per individual LED device was pathetic. This required designs utilize a number of LEDs mounted to circuit boards, wired to drivers that were clumsy at best. The complexity of LEDs in the earlier stages were compounded by the lack of available components, which meant one-off application of the technology was out of reach for anyone not up for custom electronics design.

Complexity is the Nature of Technology Growth – Part Two: The SSL Perspective

To set things off on the proper foot – I do not like complexity when it is not necessary. I’ve noted many times that if energy were free and maintenance was not a consideration, the perfect light source is the tungsten halogen lamp. This technology delivers a very attractive white light, is very easy to control, provides optical focus, and is as simple as it can get. The low voltage versions of this technology are equally attractive, accepting that transformers were a horrible thing to tag onto an otherwise neat little light source. I have made hundreds of lights using halogen lamps, mainly 12V versions, starting back in 1985. It was my go-to light source. I still have boxes of transformers and sockets, acquired over years of making lights for myself and others.

Applying LEDs in efficient lighting designs is no more complex than use of any other source, just more productive.

Applying LEDs in efficient lighting designs is no more complex than use of any other source, just more productive, and attractive than CFL or other conventional “efficiency” improving sources.

That said, there is no escaping that energy is an issue, and maintenance is a pain. The cost of operating halogen technologies is simply impossible to bear. This is why we have HID sources with all their ugly liabilities, and the fluorescent lamp.  While I get HID technology as a giant super-power halogen device, it has always been a clumsy, heavy, messy engineering gadget that sets aside the art of lighting for raw lumen energy. Fluorescent lamps have are a source you are forced to live with, in an uninspired, just-get-lumens-in -the-box sort of way. There is very little to love about their scale, lack of focus-ability, ballast hardware, delicate tubes, and ghastly glow. I’ve specified millions of these lamps into existence, wishing every time there was a better way. I never made a single art light using fluorescent lamps, not because itsn’t possible, but because I never liked them enough to give them that part of my time.

The emergence of solid-state lighting, specifically LEDs, hit me in two ways. One, I get the small controllable source I had with 12V halogen. Second, I get the efficiency and raw lumen potential of fluorescent that made it indispensable. Because of this, the last time I made a light using halogen technology was in 2004, and that product was converted to an LED sources in 2006. For my own use, every halogen light I made from 1993 to 2004 still in use around the house, has been converted to LED. Every new fixture made since 2005 has incorporated an LED light source, without exception. I do not use retrofit lamps. I either tear down and rebuild products to utilize LEDs properly, or design them around LEDs in the first place. (more…)

Tasca Test Mule Turns Two

    Flex-arm-large

The Tasca test mule turned 2 years in continual illuminated state this May. That’s 8,760 continuous operating hours in the cold, hot, and messy environment of the shop in which it lives. It gets abused as well, from tossing greasy rags over it to see what happens when airflow over the heat sink is cut off, to blowing coolant on it until it freezes. There have been several lessons learned in this time. For example, lumen depreciation, captured by measuring the fixture’s output, has been negligable. Losses have been less than 1.2% so far, which means the White Optics reflector and anti-reflective glass are doing their job, as is the Bridgelux ES Array LED. Temperature readings taken over this time have not changed anywhere, which indicates the internal construction attaching the thermal slug to the heat sink is durable and reliable. (more…)

Dimming to Warmer CCT’s – On Second Thought

Posted: February 21, 2012 in Art and Design
Tags: , , , , , , , ,

When LEDs first emerged, I was one of the many who expressed the opinion that a lighting system that could dim to a warmer CCT, imitating incandescent lamps, would be desirable. I want to take this opportunity to retract that original opinion and thought. I’ve played with it, seen the products available that do it, and have experimented with the approach… and can say unequivocally that I really don’t like it at all.

One of the problems with incandescent dimming has always been the patchwork of CCTs one gets through a space from different dimmer settings for the various products in a room. This has never been a good thing. Further, the change in CCT of an old school incandescent lamp is significantly different than halogen lamps, as it the character of the color. I for one have fallen out of love with the old incandescent lamp long ago. Over the last 20 some-odd years, I have come to use halogen sources over all incandescent forms, preferring the cleaner white color over that yellowy dinginess of the incandescent lamp. Incandescent lamps (non-halogen) produce a decidedly ugly color that I personally feel is misrepresented by their high CRI rating. The fact that the CRI formula will show a dimmed incandescent lamp with the same high CRI number, even when it very noticeably distorts color in a space, is a condemnation of our poor color performance metrics, not an indication of this lamps superior color performance.

LED vs CFL – Game ON in Side-by-Side Comparison

Working with Molex Electronics, the ZEBRA Alliance, Oak Ridge National Labs, with fixtures provided by Ultralights and Solid State Luminaires, we created a side-by-side comparison between CFL and LED in two identical homes. One uses 100% CFL lighting, the other 100% LEDs. The LED house uses Molex Transcend modular products, which incorporate 4W Seoul Semiconductor Acriche 120VAC LEDs to control costs. While the CFL home was designed by a lighting showroom, the approach in the LED home included redressing lighting design to reduce and elliminate glare, focus on delivering light where it is needed, and producing more attractive spaces that also save energy. The end result is a 70%+ savings over the CFL home. The LED home has less than 0.4W/s.f. of connected lighting load. So little energy is connected, that the entire home could have been wired to a single 15A circuit breaker (920W).

The purpose of this project is to operate both homes with controls that simulate occupied operation over 18-24 months. Over that time the performance of the two homes will be monitored using a sophisticated array of sensors and data aquisition. Lighting is just one small part of the total effort, which includes building materials, HVAC, window glazing, and roofing system performance. There are four total homes, all with identical geographic orientation, within a block of one another. The other two utilize fluorescent lighting, but are different in many other ways, including architectural design.

Below are a few of the rooms of the houses to give you an idea of how the combined approach worked out. As one can see, the difference in appearance is noticeable. At the task level, the LED house provides twice the horizontal illumination on kitchen counters and dining table, matches the CFL in the game room and office (not shown here), and provides a more comfortable light everywhere, as the light sources produce no objectionable glare. So, regardless of the LED employed not being a leading edge lumen/watt producer, the savings remain significant, while the end product – delivered illumination – both attractive and comfortable. This is an approach that will eventually set LEDs up as the preferred light source in residential application – not matching CFL glare bombs, but delivering an improvement in lighted quality as well as energy saving.

For those attending the LEDs 2010 conference this month (Oct 25-27) in San Diego, I will be presenting this project with some background and more detail there.  Stop by and say hello if you are in the area:
