Throw-Back-Thursday! How is the life of an LED lamp determined?

With traditional lamp sources like halogen, fluorescent and metal halide, a selection of lamps (usually somewhere around 100 samples) are burned continuously at a given voltage and position. When 50% of these lamps have ceased to function, then this determines the lamp life for that particular lamp.

CRI Is Not Necessarily the Proper Measure of Light

Everyone in the lighting industry knows CRI and they know it well. It is the go-to metric for quality of light. But, why? Let's disprove the metric and talk about if TM-30 will prove to light the way!

Lighting Basics - What is Color?

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?"

OLEDs VS. LEDs - What's Feasible in General Lighting?

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.

Throw-Back-Thursday! Beware of Making Comparison Mistakes With Halogen Lamps

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.

What's the deal with CRI?

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...

Sulfuration - What is it and what does it do?

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.

TM-21 Testing Explained

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.

Transformer Compatibility Challenges

One of the current challenges in the LED industry is transformer compatibility for low-voltage LEDs. MR16 LEDs are at the forefront of the issue, but not an issue with the LED MR16s themselves. The issue exists with the transformers.

Why is LED binning so important?

As seen in the figure 1 below, white light falls along the Planckian Locus (or black body locus) on the Chromaticity Diagram. This means that depending on where the white light falls along the black body locus, the light can be bluer or yellower than another white light.

Glare

Glare is defined as a visual sensation caused by excessive and uncontrolled brightness. It is subjective and sensitivity to glare can vary widely.

ETL Vs UL

Why aren't Solais lamps UL listed? Why are they ETL? Which is better ETL or UL? We at Solais get asked these questions all the time. I'm going to try and briefly explain the ETL vs. UL showdown here.

And now for something completely different... LM-80.

Why doesn't Solais provide LM-80 results on their lamps? That's because LM-80 refers to the LED itself, outside of its environment.

What is an LM-79?

Why doesn't Solais have LM-79 certification? Well, that has a simple answer, there is no such thing. LM-79 is a testing process not a certification.

Understanding Optics and the Benefits of LED Optical Control

The most common mistake in lighting terms associated with the quantity of light is between the intensity of a light source and its total output. The total output of a light source is described in "lumens".

What you should know about LED Lighting

LED sources are a new solution for virtually all lighting needs and have the potential to change the way we live and consume energy. The largest limitation currently slowing the adoption of LED lighting is simply that it is new and not well understood.
