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.

ArchLED’11 will be marked as the official coming out for Tasca, my work lighting product offering. We presented examples of the base Uno line, as well as several Renovar and one Accent light. If you are wondering what these are, and are curious to learn more, you can visit the Tasca web site now. The sitre is fully populated with pictures and a specification download at:
While I do not intend to make this blog a commercial site promoting products and pitching our offerings, I do need to make a living, so there will be occasional updates to share where we are and what we are doing in this regard. This is how we pay for the fun side of being in the business, and afford the time to invest and share with others information on solid-state lighting.
A Little More on Tasca
Tasca is primarily focused on the work environment. Whether this is a machine operation, an assembly work station, an inspection station, or administration workplace, my intent is to offer the most effective light for enhancing visual performance with a durable product. I’ve invested decades experimenting with task lighting. My personal approach has been to lower ambient surrounding light levels to the minimum required to support the low acuity activities in the space, supplemented by localized task lighting to enhance visual performance in critical work areas. I have applied this in lighting designs over the last 30 years to reduce energy consumption, and live under it on a daily basis. In other words, I am passionate about this approach and believe it is a superior approach to achieve high visual performance. I strongly believe we are over-lighting our work spaces to some compromised light level, which is too high for ambient requirements and too low for effective task performance.
Over the last few years, the idea of creating a work light for hard service environments, bringing the advantages of SSL technology to work spaces that require high visual performance to support safe, accurate, and efficient work tasks. For over a year now I have been investing considerable time building a product I feel satisfies the demands of work environments, with an efficient product that will survive harsh environments. Tasca is the product of this effort, and just the beginning of a larger effort to produce desirable performance SSL lighting products for niche work space demands. We’ve already provided customized versions of Tasca for UV curing applications, and will be releasing specialty products, such as a 98CRI sourced heads for color critical inspection (like printing presses, millwork, textile and paint inspection), as well as a unique welding light that will bring welders vision of their welding field that has never been possible before.
Tasca is also founded on the concept of sustainability from durable products that are recycled either by dismantling, rebuilding, or re-purposing at the end of service life, not just thrown away. Unlike products that are filled with potting materials and irreversible assembly techniques that make recycling too expensive to be practical, Tasca fixtures are heavy duty assemblies designed to be reworked, rebuilt, or dismantled easily for recycling of materials content, separate of the electronics components that must go through a separate recycling channel. This includes the use of glass for the lens cover, which can survive decades of use, or be recycled easily through existing waste management channels economically. The Renovar and Accent line take all of this one step further by harvesting old task lights for their arms, refinishing the devices, recycling the old lighting heads, and converting them to Tasca lights by adapting our lighting heads, before a complete refinish and refurbishing.We will also refit your existing task lights, bringing old favorites back to life by bringing them up to date, or through Accent, create a custom design to suit your specific taste.
This is just the start of a great deal more to come. Sort of pulling the plug out of a dyke and letting things flow. This is an exciting niche opportunity for me, where I can add value through design integration assistance, and provide customization to suit unique customer needs. Unlike imports which must be marketed in large batches of off-shelf products to move production inventories – Tasca is made here in the USA, to order, to meet individual customer needs – even if that means building something completely new and unique that has a total customer market of one.
