Seoul Semiconductor has pre-released a series of LEDs it has claimed to produce near sun-like color and SPD at an impressive 97CRI. The marketing message is that this represents a breakthrough in delivering a more natural light to the eye, thus supporting improved health and well-being. Here is their claim, specifically: Read the rest of this entry »

When you spend a lot of time at the controls of word processors, spreadsheets, design software and 3D CAD, you may find that the pedestrian swill keyboards and mouse devices from the office supply and consumer electronics stores inadequate. I know I do. I used to go through a keyboard every year, and suffered from mouse fidelity issues (lack thereof). What I have found a superior approach is to using gaming interfaces. Gamers beat and pound away at their equipment, and subject them to real uses and abuses that office equipment is just not the equal of. Gamers also demand far more precision and consistent response. All good things for design uses. Read the rest of this entry »

The AMA has stepped in to take the stand that warm color LEDs are the only products suitable for street lighting. For anyone interested in this, please read it before assuming you know what it says. There are several factual errors in this document. Most in the lighting design business will see them. The LRC has issued a response to this document.  The IES has also issued its own response.   Again, for those interested, read all of these documents before blowing a gasket and spewing conspiracy theories into the realm, deriding the IES, the LRC or the AMA. It is probably worthwhile also to include the recommendations and statements of the IDA (Dark Skies) as they are the ones who actually initiated the <3000K solution. Read the rest of this entry »

Product development and management has evolved from the days of taking a shot on a hunch. In the days of fabricating products with minimal tooling, the risk of failure was low, and profit reward for success quite good. Who needed product management? Design it, build it, catalog it and get it to the reps and wait for the orders to roll in.

The lighting industry also has a long history of operating with lean management structures, particularly in small organizations. Ownership, Marketing, Engineering, Finance, Design, Engineering, and Sales all have a role in product development, planning and line maintenance. How well product management tasks are accomplished is Read the rest of this entry »

The Mythical Imagery of an Irrelevant and Laggardly Lighting Designer Singularity

The scuttlebutt among select vocal SSL technologists and aggressive LED lighting marketeers derides the “Lighting Design” community as a singularity, and a lot of plonkers, that know nothing about technology, who are so focused on lighting surfaces they ignore the needs of human occupants. Some go as far as accusing Lighting Professionals of gross negligence and malpractice. A few others proffer a theory that conventional lamp manufacturers and their simple technology have propped designers up – that the emergence of LED has exposed them as technical posers, who know nothing of photo-metrics, glare, and visual comfort. Others point to statistics showing “Lighting Designers” are involved in just 5-10% of product decisions to prove them irrelevant. To these antagonists, it must seem a mystery how Lighting Designers have escaped exposure for so many years. Read the rest of this entry »

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.

My center all touch-stone and tribute to the mechanical arts that compete at the Bonneville Salt Flats every year.

The “Internet of Things” has now become the newest, hottest marketing powerhouse. The scale of claims and the breadth of its application transcends lighting, so it eclipses popular lighting themes of Energy Efficiency and Human-Centric Lighting. The idea of everything being connected through the internet, accessible, upgradable, and monitored from anywhere at anytime is the big sell. Refrigerators that not only tell you when a product has expired, but automatically places an order for a replacement is one proposed far-reaching concept. Products that learn from our use cycles to adopt and send data to manufacturers for product development is another. Lighting that responds to local natural light conditions without local sensors. Power grids constantly adjusting in anticipation of user demand. Facilities managers, utilities, and end users accessing and monitoring building activity, condition, and Read the rest of this entry »
