LED FAQ

The lighting industry and the way people use light changed forever with the introduction of the Cree® LED bulb. For the first time, the new Cree LED bulbs provide a compelling reason to switch from energy wasting incandescent to LED. The revolutionary LED bulbs demonstrate how something as simple as lighting can have a profound effect on how people live their life. The new Cree LED bulb is what everyone has been waiting for – a bulb that looks like an incandescent, lights like an incandescent, uses a fraction of the energy, lasts for years and is at a price people can afford.
Thomas Edison said, “There’s a better way to do it. Find it.” Cree took that challenge to heart with a great, simple, timeless design made possible through relentless LED innovation. Inventing the LED technology that delivers light like an incandescent was hard work, but designing a bulb in a form-factor that consumers trust at a price they can afford was even harder. Designed with Cree LED Filament Tower™ Technology, the Cree LED bulb represents a breakthrough in LED bulb design and performance. Unlike the large, dull glow produced by CFLs and other LED bulbs, the Cree LED Filament Tower creates the same nuance and visual texture as a traditional incandescent bulb by emulating the compact light source of an incandescent filament.
Until the introduction of the Cree LED bulb, consumers had few options. They could keep using incandescent bulbs that provide high quality light, but waste energy and therefore cost money every minute they are used. Or they could opt for flawed alternatives. Until today existing LED bulbs could fall into two categories; good light, but expensive – or poor light, but cheaper. In all cases, they failed the consumer. Cree solved the problem! Cree LED bulbs with the Cree Filament Tower Technology breaks the $10 price barrier, looks like a typical light bulb, but works better. Cree LED bulbs save 84 percent of the energy compared to typical incandescent bulbs, are designed to last 25 times longer and come with an industry leading 10 year limited warranty.
Cree’s mission is to obsolete energy wasting light bulbs and drive 100% adoption of LED lighting. Engaging the consumer as an ally is an important factor to realizing this mission. In our relentless efforts to innovate and improve LED lighting, we developed a breakthrough that allowed us to overcome fundamental obstacles to consumer adoption of the LED light bulb – great light quality in a simple design at an affordable price. Cree has a long and successful history of pushing the LED lighting market when it isn’t moving fast enough. The new Cree LED bulb showcases innovations across LED chips and components, optics technology, systems and overall bulb design. The result is a high quality, long lasting, affordable LED bulb that consumers can trust to replace their existing incandescent. The Cree LED bulb gives consumers a reason to switch. We believe this breakthrough LED bulb will, for the first time, motivate consumers to upgrade the billions of energy-wasting light bulbs installed in their homes.
Cree LED bulbs are available for purchase in The Home Depot stores and online at www.homedepot.com.
The Cree LED bulbs are easily dimmable with most widely available standard incandescent dimmers.
The new bulb is designed to last 25,000 hours, 25 times longer than typical incandescent bulbs (1,000 hour lifetime*) * 60-watt incandescent bulb has a typical lifetime of 1,000 hours, according to the U.S. DoE.
The Cree LED bulbs feature an industry leading 10-year limited warranty.
Cree earned ENERGY STAR® qualification for the soft white Cree LED 40-watt and 60-watt replacement bulbs.
Yes. Soft White and Warm White are interchangeable descriptors to indicate the color temperature of the light that the bulb emits. Soft/Warm White bulbs emit a light temperature of 2,700K.
Light that is emitted from the light source is measured in lumens. The higher the number, the brighter the source will be.
The Light Appearance value on the Lighting Facts label indicates the hue and temperature of the color emitted within the light spectrum in ranging from 2700 to 6500 Kelvin. "Warm" colors have lower color temperatures (2700–3500 K). Warm/Soft LEDs create an inviting, comfortable, and relaxing atmosphere, and highlight golden and red tones to add a peaceful aura to any space. "Cool" colors have higher Kelvin temperatures (3600–5500 K). Cool/Daylight LEDs create a bright, clean, and lively mood, and inspire active areas in your home with intensely vibrant streams of light.
Watts is a measurement of energy that is required to illuminate the light source. The lower the wattage, the less energy used.
Color reproduction is an important characteristic of any type of lighting, including LED lighting. Color reproduction is typically measured using the Color Rendering Index (CRI). CRI is measured on a scale up to 100. The higher the CRI, the more accurately you will see the actual colors of objects that the bulb illuminates (i.e. reds will look red). Daylight has the highest CRI (~100), with a 2700K incandescent bulb being relatively close, and fluorescent lighting being much less accurate (CRI 70-85). Certain types of specialized lighting, such as sodium lights (street lights with yellow orange colored light) exhibit a relatively low CRI (as low as about CRI 20 – 30). The Cree TW Series LED bulb has a high CRI of 93, unmatched for LED bulbs, making colors look the way they were intended.
Neodymium is a naturally occurring element (#60 on the periodic table) that is added to the glass of the Cree TW Series LED Bulb. The addition of this element gives a unique-looking blue/violet tint to the glass bulb, and augments the LED light that passes through it and greatly increases the CRI of that light.
The addition of neodymium in the glass of the bulb affects the LED light passing through the bulb to create a “spectral notch”. A spectral notch is a portion of the color spectrum where the light is attenuated thus forming a "notch" in the spectrum. By notching a portion of the yellow light, you get a higher contrast between reds and greens which brings out the true colors of what is illuminated. What remains is LED light that has a higher CRI.
Yes, The Cree TW Series LED Bulbs are the first to meet the stringent requirements set for LED Bulbs by the California Energy Commission in the Voluntary California Quality Light‐Emitting Diode (LED) Lamp Specification.

The warm white 40-watt replacement uses 6 watts. The warm white 60-watt replacement uses 9.5 watts. The day light 60-watt replacement uses 9 watts.
We're excited to partner with The Home Depot®. The Cree LED bulbs are available at The Home Depot in the United States, Canada and Mexico. The Cree LED bulbs are also available online at www.homedepot.com.
Cree LED bulbs will begin arriving on store shelves and online at www.homedepot.com on March 5 and will be in all 1,976 U.S. Home Depot stores by March 21, 2013.
The Cree LED bulb produces an omni-directional light and turns on instantly to full brightness. The 40-watt replacement bulb is available in warm white (2700K) color temperature and the 60-watt replacement is available in both warm white and daylight (5000K) color temperatures to meet consumer preferences.

The Cree TW Series LED bulb has a high CRI of 93, unmatched for LED bulbs, making colors look the way they were intended.
The higher the CRI of a bulb, the more accurately you will see the color of objects illuminated by its light. According to ENERGY STAR®, a bulb with a CRI of 80 is the minimum acceptable for ENERGY STAR qualification. According to this standard, anything below 80 could be considered poor CRI light. A light bulb with a CRI of 80 is a excellent general use bulb for the home.
Yes it is - but good enough for what? For general illumination it is fine. But there are certain applications where a higher CRI light might be preferred. In places where you want to accurately display the colors of fabrics, woods, food, skin, you may want a high CRI light source to see the true and natural colors.
Not exactly, not all 80 CRI bulbs are the same. LEDs produce light with a broad color spectrum, like natural light has, while CFLs have very narrow bands of color, forcing your brain to fill in the missing color gaps. Many people find this disturbing without even knowing why. Both may have a similar CRI, but in fact the CFL light is a much poorer quality of light.
Currently, the limited offerings of A19 bulbs with greater than CRI 90 is small and these bulbs offer a variety of compromises including higher price, shorter warranty, and non-optimal optical performance.
