I’m going to go right at this one head on. The assumption of quality being equated to price paid is a marketing strategy. There is no irrefutable fact or reality associating price with quality. This does not mean that high quality is not a value worth paying for. I am also not saying that there is no justification for paying a higher price to attain a higher level of quality. What I am saying is, the connection between cost and quality is not inseparable. You can achieve high quality at a low price, and you can suffer low quality at a premium. The region between bargain and rip-off is vast.

Design is the work of assigning an appropriate level of quality in application and product selection, within the need and desire of the customer

To get a handle on this, let’s take a moment to define quality in minimal terms. I believe product and design quality is a composite of three core factors.

  1. Performance that meets the intended demand. In other words, does the product and/or design serve the need and desire of the customer?
  2. Physical integrity. Does the product and/or design include a high degree of fine fitment and refinement of finish, with minimal or no flaws appropriate to the intended use and application? Is the product and/or robust enough to endure or exceed the intended service lifetime?
  3. Service after Sale. Does the provider of the product and/or design stand behind the product, resolving any unforeseen error or failure in a timely and satisfactory manner?

There are a great many pleasant, long-lasting, efficient, quality environments designed using modestly priced products well-selected.

I have taken a break from publishing to this blog for several months for a reason. I needed some time to stand back and observe and listen without intent to respond or contribute, and to seek counsel of others. The lighting industry has been in a state of flux for more than a decade now. As a veteran spanning over three decades, there is nothing new in this. Here’s a bit of news for those new to this business – the industry has been in flux for over three decades now, the intrusion of solid-state technology is just one more in a long series of adjustments. However, the most recent decade has brought a new character to the industry that, frankly, stinks.

SLA printing uses laser light to cure resin in a bath to generate 3D parts, one layer at a time. The finished parts are smooth, with finer detail than what can be accomplished using (Fused Deposition Modeling), which extrudes plastic that is deposited in layers to build a part on a build platform. However, SLA printed parts require post processing to make them usable, even for model creation. Each part required excess uncured resin to be cleaned away, usually in an alcohol bath. Further, to eliminate surface stickiness and improve overall strength, it is necessary to use light cure conditioning to complete the curing of the finished model.

For desktop printer owners, the search for an economical post-process light cure solution leads to low-cost solutions. One such solution is to purchase tape light strips. These are inexpensive and operate from simple low voltage power supplies. They can be purchased from e-bay for a few dollars, and proclaim high-efficiency and violet light. Most use a standard mid/low power 5050 LED package and deliver anywhere from 395 to 410nm of violet light.  Another approach, which we have attempted, is use of 5mm LEDs in arrays on a simple custom circuit board.

Before I go any further, I will state now that after extensive testing and experimentation attempting to discover a super-low cost light cure conditioning solution, none of the low-end, low power Read the rest of this entry »

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 Read the rest of this entry »

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 Read the rest of this entry »

The ubiquitous Dazor Desk lamp. There has to be millions of these still in use. But, there is only one that can do what this one does!

Task lighting is a passion, so that means gathering my share of collected old-timer fixtures that are iconic, or representations of a product that is familiar and comfortable. In this case it is the Dazor desk lamp. I have these in drafting board mount, and have made on floor lamp from a similar foundation. I don’t use fluorescent tubes in any of them, and Read the rest of this entry »
