In recent developments, the new CREE LED native modules offer enhanced thermal performance and reduced system-level costs, driving further adoption in multiple applications such as horticulture and architectural lighting. This advancement underscores the ongoing innovation in CREE LED technology, providing even greater versatility and efficiency.

Cree LED Lighting downlight and lamp products have electronic drivers that are “reactive” (capacitive and/or inductive) and draw very little power (10-11 watts). These two factors result in electrical current that is just barely above the minimum holding current for most dimmers, and below it for others. There are other factors specific to the installation site, such as neutral-to-ground integrity, power line noise coming from the utility or other loads, and source impedance. With the minimum holding current requirement barely being met, these other factors can cause the current to dip below that threshold, resulting in occasional dimmer mis-firing which can result in a faint flickering coming from the lights.

Cree LED Lighting tests its products with a variety of dimmers, and makes recommendations regarding compatibility based on those results, but cannot guarantee performance.

The LR4™ and LR6™ product families are designed to dim down to ~25% of full brightness, then turn off when dimmed below that. Due to the nature of LED light, this can appear more like 40%-45% when looking directly at the fixture. Examining the room being illuminated will give a more accurate perception of actual brightness.

The CR6™ and LR24™ products are designed to dim down to 5% of full brightness. Due to the repetitive peak currents generated by the inrush current of LED lighing fixtures, Cree products should be treated as a 75 watt load when sizing dimmers.

Whether you are camping in the great outdoors or working on a project in your garage, having good lighting is essential. Investing in quality lighting can save you both time and money but there are so many lighting options to choose from. One internationally recognized, and frequently duped, high-quality light technology is the CREE LED.

CREE LED lighting is a mercury-free light technology that combines CREE LED’s proprietary optical design and wafer-level sub-mount packaging to maximize light extraction efficiency in reliable low profile lighting options such as outdoor, task lighting, and automobile dashboard illumination.

Known for their quality, CREE LED’s offer practical lighting solutions to everyday tasks. These can be found in our hands-free lighting units such as the FLEXIT Pocket Light and the FLEXIT Headlamp Pro for an easy and convenient way to complete your project with accuracy. Now that you know what a CREE LED is, you may be wondering how it differs from other LED light technologies on the market.

The CREE LED came out of necessity for an LED white light. At the time, conventional incandescent lightbulbs contained diodes that could only emit red and green hues casting the conventional warm lighting we know of. In an effort to achieve a bright white light, the goal was to create a blue-emitting light to combine with the red and green hues which would then appear, to the human eye, to be bright white. 

Initially, CREE just made fine-crafted chips and sold them to other light manufacturers but upon acquiring their own light manufacturing facilities they were able to create the CREE LED which could soon be found in Volkswagen’s dashboards, backlighting digital devices, and in various other lighting systems. 

Recently, the integration of CREE LEDs in smart lighting systems has further expanded their usability, offering smart home lighting that can be managed via mobile applications and voice control interfaces. This innovation is part of the broader trend towards smarter, more connected home environments.

CREE LED lights quickly became synonymous with quality in the lighting industry and as a result, many other lighting companies attempted to mimic the brand. Nowadays, while other LED brands also offer efficient chip cathodes and long-lasting light sources, they have yet to match the quality of the original CREE LED.

Not only did CREE LED lights champion reliability and longevity in the light itself, they also paved the way for lighting that can increase safety, reduce eye strain, and offer customizability to meet your project needs.

In a conventional light bulb, electricity flows across a wire in an oxygen-free glass bulb creating its glow. The CREE LED system uses light-emitting diodes to emanate light with maximum efficiency, cost-effectiveness, and without the flickering of a conventional fluorescent light tube. CREE LED lighting is also known for reliability and an exceptional lifespan. 

In terms of cost-effectiveness, while a conventional light bulb may be cheaper upon initial purchase, it is likely to burn out in two years whereas, the CREE LED light costs a little more but lasts up to twenty years. If that alone does not sway your favored lighting choice, we will continue to compare the CREE LED to other lights.

While LED lights tend to outperform conventional incandescent lightbulbs in all ways, LED lights themselves are not all created equal in terms of quality. The following table shows a few elements of qualitative value that CREE LED lights possess over standard and fake CREE LED lights. 

The average rated life of a light bulb is the lifespan of a light bulb, determined by how long it takes half of the lightbulbs in a test batch to fail. The decay rate of a lightbulb is indicative of the luminosity lost every 1000 hours of use showing how brightly the light emitted from a bulb remains over the time of its use compared to its original brightness. The luminosity is the measure of how bright the light emitted from a bulb is.

When you invest in CREE LED lighting systems, you are empowered to focus on tasks at hand as you will not have to worry about changing light bulbs frequently, the quality of the lighting, nor the energy expended on lighting. CREE LED lights are the more environmentally friendly option as well since the bulbs need replacement far less frequently, if at all, during the lifespan of a product along with minimal use of energy when turned on.

Having good lighting when working on projects is crucial to being able to complete them safely and accurately. Investing in a general work light may work for a while however, the cost to frequently replace bulbs can add up. Conventional lighting can also be softer and more diffused whereas, the CREE LED offers focused, bright lighting and bulbs with an impressive lifespan, meaning more time to focus on the task at hand.

Lumens, defined as the measurable amount of light given off by a light source, should be considered when deciding optimal lighting for your activities and projects. It has been found that 500-1000 lumens are the ideal range for work lighting. 

The FLEXIT Headlamp Pro lighting system contains CREE LED technology offering up to 650 lumens providing optimal work light conditions while keeping both hands free. In combination with C.O.B. flood LEDs, the CREE LED on this device is can project its 350 lumens of light well into the darkness, creating phenomenal lighting for late night work and camping adventures. 

If you are partial to spending time in nature, camping, or hiking, safety is of utmost importance. One item that is essential to pack is a proper flashlight. The FLEXIT pocket light is a convenient, multi-use flashlight that enables the user to target the light where needed.

Containing CREE LED lighting as a spotlight, this long-lasting flashlight has a luminosity of up to 650 lumens with adjustable brightness and dimming abilities. Because of the enduring nature of CREE LED lighting, you do not have to worry about the reliability of light when you are outside in the dark or working in a cramped dark space. 

Because of the quality of CREE LED lights, there are plenty of knockoffs that exist in the lighting market claiming to be CREE LED but as we saw in the comparison above, the quality is not comparable. One way to find out if you have a genuine CREE LED is through the chip used within the lighting system. CREE uses a distinct cathode design identifiable by the neat soldered design that separates the cathode into distinct rectangles. 

Fake LED lights claiming to be CREE LED can similarly mimic the chip style of an authentic CREE LED but upon closer inspection, the lack of detail and fine craftsmanship on the cathode is apparent. Checking the chip for authenticity can be done with a microscope or magnifying glass, as it is quite compact. 

Though many other lighting brands have attempted to create their own version of the CREE LED, none have been successful thus far.

CREE LED lights have revolutionized the possibilities of what can be achieved with light. With their long lifespan and minimal energy usage, CREE paves the way for lighting innovation. When you purchase a lighting system containing a CREE LED, you can be certain the quality will speak for itself while reliably lighting the way for your projects far into the future.
