Here is where it gets out of this world – LED light plant growth has even reached outer-space. Astronauts currently living on the International Space Station (ISS) are now able to grow their own food under LED lighting and actually eat it!

5 Reasons You Should Switch to LED Lighting: Performance, Versatility, Environmental Impact, Control, Maintenance

When talking about lighting, the topic of color is often the driving force behind product selection. It’s a word we have all used so much in different context. We have been talking about color since we were toddlers. It’s one of the first things we are taught (in addition to numbers), but technically, in itself – it doesn’t exist. So, that begs the question – what is “color?”

For many years, (light-emitting diodes) struggled to fulfill their promise as the dominant technology for the next generation of general-lighting. As the major LED manufacturers began to expand capacity (thereby driving down costs), many end users continued to complain about color quality, usable-life claims and the actual return on investment. Through this feedback, manufacturers realized that the requirements for the general-lighting market were not synonymous with those of the automotive, display or indicator markets.

We recently evaluated the Solais LED LR38 (21W, 1000 lumens) against a PAR38 halogen (90W, 130V, 1310 lumens) for a high-profile client. The client had some initial concerns due to the apparent large difference in lumens between the two products, but this was simply because they did not have a proper understanding of the importance behind the 130V rating.

Nobel Prize in Physics is awarded to 3 scientists who developed the blue LED

Our white paper, VioLight- Improving Color in Real-Life Applications, brings up an interesting new perspective on how to measure color in lighting. It’s all about CRI, right? Well, sort of…

One of the “dirty” secrets of the LED industry is that chemicals in the surrounding environment to some types of LEDs can cause a decrease in output or potentially accelerate complete failure. Probably the most common mechanism is referred to as “Sulfuration” because it involves the chemical reaction of sulfur and silver.

In a previous blog post, we detailed LM-80 testing, how it relates to our LED devices, and how it provided the LED lighting industry with a unified testing methodology. Since LEDs and LED devices have longer lifetimes than many other lighting technologies the problem arose as to how long of a testing period would be needed.

Halloween was over a month ago with the winter holiday season already under way. In the tradition of “The Nightmare Before Christmas”, let’s talk about scary TM-21 calculations.
