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-emiting-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 in front 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 this handy ditty is 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.

1. Conservation

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:

LED Conservation
  • 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

2. Clarity

LED Clarity

Say goodbye to flickering, 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.

3. Contrast

LED Contrast

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.

4. Color


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 more “true” colors will look under its light. This measure is something especially important for architects, designers, and anyone who frequently evaluates colorful art and graphics.

  • CRI - Color Rendering Index: 85 or higher for vivid, brilliant colors, free of haziness or discoloration

Don’t be fooled by modern myths – not all LED’s produce the same bluish-color light! While an LED bulb with a 5000 Kelvin color temperature provides the highest level of contrast while replicating natural daylight, PureOptics LED’s are available in multiple color temperatures. From warm accent lighting, to bright-white task lighting, you can choose a product to produce the light temperature you desire. A general rule of thumb to follow is the higher the Kelvins, the closer to a natural daylight light temperature. As the Kelvins move lower, the LED light becomes warmer.

LED Color Temperature Differences

Color Temperature:
  • 5000 Kelvins: Natural Daylight
  • 4000 Kelvins: Cool White
  • 2700 Kelvins: Warm White
