The basics of LED lighting

Simon BaierKnowledge Base, LED, Lighting technology1 Comment

Knowing the basics of how light-emitting diodes (LEDs) work can help business and builder owners decide if the energy efficient lighting option is the right solution for them. LEDs are a solid-state lighting technology (SSL), which means the light is emitted from a semiconductor – also known as a solid matter.

What is a Lighting Ballast?

Simon BaierKnowledge Base, News2 Comments

A lighting ballast has three primary functions: first, establish an electric arc through the lamp; second, limit current through the lamp after ignition; and third, compensate for variations in line voltage and ensure consistent lumen output. Learn the difference between traditional core-and-coil, and newer (and better) electronic ballasts …

Ceramic Metal Halide Lighting Basics

Simon BaierKnowledge Base, NewsLeave a Comment

Ceramic Metal Halide is relatively new light source, touted for being compact, efficient, and powerful. CMH is part of the high-intensity discharge (HID) lighting category, which offers the highest efficacy and longest life of any lighting type, and saves up to 90% of lighting energy when they replace incandescent lamps.

Illuminance Explained

Simon BaierKnowledge Base, News1 Comment

Illuminance is the amount of light striking a surface – also known as incident light, where the “incident” is the beam of light actually landing on the surface. Lumens are a measure of the quantity of light, referred to as luminous flux or just flux, emitted by a light source. When considering lighting applications, illuminance is used to measure …

What is Full Spectrum Lighting?

Simon BaierKnowledge Base, News3 Comments

Lighting spectrum – Natural and artificial lighting. Light, as we humans see it, is electromagnetic radiation that’s visible to the human eye. It’s the part of the electromagnetic spectrum we call “visible light”. The electromagnetic spectrum is the range of all frequencies, or wavelengths, of electromagnetic radiation – from very low energy frequencies like radio waves, to radiation with very … Read More

Is Color Quality Scale (CQS) an improvement on CRI?

Simon BaierKnowledge Base, News6 Comments

Solid state lighting industry at an impasse efforts to replace CRI with CQS (Color Quality Scale) As advances in solid state lighting products, especially LEDs, continue to push into the marketplace displacing incandescent and fluorescent lighting products, it only stands to reason that evaluation methods for these products, such as the measurement of color fidelity, or CRI – now almost 50 … Read More

What is Color Rendering Index (CRI)

Simon BaierKnowledge Base, News2 Comments

CRI measures on a scale of 0 to 100 how a light source shifts the location of eight specified pastel colors compared to the same colors lit by a reference light source of the same CCT. A CRI of 100, or perfect color rendering, means the light source renders the eight colors exactly how the reference light source renders them.

LUMENS: The new way to shop for light

Simon BaierKnowledge Base, News

New federal lighting regs to help consumers make ‘green’ lighting choices Starting Jan. 1, 2012, new federal regulations will require the most common light bulbs to be more energy efficient. Specifically, bulbs must produce the same amount of lumens (light output) for less wattage (energy consumption). All packages of light bulbs sold in stores after the New Year will carry … Read More
