The 4 C’s of PureOptics LED Lighting


It’s no surprise that the use of LED’s in today’s lamps, fixtures, and appliances is quickly overtaking that of traditional incandescent and fluorescent bulbs. Today, we know that LED (light-emitting-diode) bulbs last longer and use much less energy than the traditional high-wattage bulbs of our childhood. But energy-efficiency isn’t the only desirable feature of a high-quality LED. Does the light flicker or create a glare? Is the light’s color temperature so warm that you feel like you’re on a beach in Florida, not at your desk in the office? Is it difficult to read the fine print on documents or see colors accurately on printed graphics and ads?  These are all things to consider when purchasing an LED light and, consequently, something we kept on top of mind when creating our PureOptics LED technology. That’s how the 4 C’s of PureOptics Technology were born!  Ever hear of the 4 C’s of a diamond? Turns out these handy terms are a great way to remember the important features of a high-quality LED light. Read on to learn more about the 4 C’s of PureOptics LED lighting and the important things to consider before making your next lighting purchase.



Our eco-friendly, cost-efficient LED’s reduce energy consumption and deliver brilliant illumination for up to 15 years. If you are interested in reducing your monthly electricity bill while doing your part to save the planet, then you’ll want LED’s that:

  • Contain no heavy metals
  • Feature zero UV emissions
  • Are long lasting – for 15 years or 30,000 hours
  • Use 85% less energy, compared to incandescent bulbs



Say goodbye to flickering lights, hotspots, and glares. Work, play, and create with unparalleled clarity under a flicker-and-shadow-free, extra-wide light zone that is crisp, sharp, and clear. High quality PureOptics LED lights feature a level of clarity that you won’t find in traditional light sources. PureOptics Technology has a flicker-free performance and an optimizing diffusing element that casts an extra wide light zone that softly fades to eliminate hot spots.  When shopping for an LED light, especially when it will be used as task lighting, look for a product with a high level of clarity.



See fine details with unsurpassed visual acuity under high-contrast, comfortable lighting that mimics natural daylight and reduces eyestrain! PureOptics LED’s provide a high level of contrast ideal for task lighting. These types of LED’s are designed to replicate bright, noon-time lighting, the time of day when the sun is overhead and creates the most contrast. At a 5000 Kelvin color temperature, PureOptics LEDs are both mood-boosting and at the highest contrast in the spectrum. The higher the Kelvins, the brighter white the color of the light. As the Kelvins become lower, the color temperature becomes warmer.



Experience vivid, true-to-life colors across the visual spectrum that are free of haziness and discoloration with high CRI PureOptics LED technology. CRI or color rendering index is a measure of a light’s ability to reveal the true colors of an object. The higher the CRI of an LED, the “truer” colors will look under its light.  With a color rendering index of 85 or higher, the more vivid and brilliant colors will appear, and they’ll be free of haziness or discoloration. This measure is something especially important for architects, designers, and anyone who frequently evaluates colorful art and graphics.

Other Lighting Terms to Know:

Lumens – Measure of the total quantity of visible light emitted. A high lumen output creates brighter whites and darker darks.

Lux – One lumen per square meter. Often refers to the intensity of a light source.

Efficacy – Lumens per Watt - measure of how well a light source produces visible light.

CCT (Correlated Color Temperature) – Another way to refer to the color temperature of a light and is measured in Kelvins.

Watts – A unit of measure for the rate of energy transfer no longer relevant with LED’s.

CRI – Color Rendering Index – a measure of a light’s ability to accurately reveal the colors of an object. Go with 85 or higher for vivid, brilliant colors, free of haziness or discoloration.

Color Temperature (Kelvins) – The color of the light, measured in Kelvins. The higher the Kelvins, the brighter white the color of the light. As the Kelvins become lower, the color temperature becomes warmer.


The next time you are lost in a sea of colors, lumens, eco-friendly claims, and CRI’s, remember the 4 C’s of PureOptics LED Lighting!
