Outdoor IP65 UltraBright™ Sienna Dim-to-Warm Series LED Strip Light


Our Outdoor (IP65) UltraBright™ Sienna Dim-to-Warm strip creates more than beautiful light. It not only simulates the dimming of an incandescent lamp as you dim it, producing a candle-like glow similar to traditional incandescent lighting, but it does it with innovative versatility and peak performance to set the tone to create memories that last a lifetime.

The Sienna™ Series is easily dimmable and controllable with TRIAC dimming (MLV, and ELV), PWM dimming, and 0/1-10V dimming. As the lights dim, they automatically warm from 3000K to 1800K. 

These LED strip lights are IP65 rated, which means that they are able to withstand low-pressure jets and splashes of water from all sides, are completely protected against dust, and are very easy to clean. Whether you want to brighten corners, beautify gardens, or create the perfect ambiance in an outdoor space, the Outdoor (IP65) UltraBright™ Sienna Dim-to-Warm is here to help.

UltraBright™ Sienna Dim-to-Warm LED strip light FAQ:

Q: What is Dim-to-Warm?

Dim-to-Warm is a technology that lowers an LED’s color temperature when dimmed, allowing for smooth variations in warm white light (from 3000K to 1800K). This was designed to imitate the familiar, natural feeling of dimmed incandescent lighting, while delivering highly efficient lighting.

Q: How Does Dim-to-Warm Work?

The UltraBright™ Sienna Dim-to-warm strip light has an internal control circuit which dims the 3000K LED chip first and later starts to control the current of the 1800K chip. The color temperature gets warmer when dimmed. Dim-to-Warm follows a dimming curve to simulate the dimming of an incandescent lamp. The technology allows standard dimmers to provide sophisticated control and smooth, natural dimming.

Q: What is correlated color temperature? (CCT)

The color of light can be quantified by referring to its color temperature. White light is measured in Kelvins (K). Most white lights fall in a spectrum between 1800K and 6200K. When dropping below 3000K, the light becomes noticeably warmer. On the other end of the spectrum, the lights become cooler and emit a blue-ish tint as they rise above 6500K.

Q: What is the product warranty?

Because of our unyielding confidence in the quality of our product, we offer a 15-year warranty on our UltraBright™ Sienna Dim-to-Warm Series LED strip lights. For more info, please read our warranty policy.

Q: What do I need to turn on my lights?

To turn on these LED strips, you will need to connect them to a 24V low-voltage power supply. The type of power supply may vary, as you can use a Dimmable power supply and pair it with an AC wall dimmer, or use a non-dimmable power supply with a single color compatible controller. We recommend using our solderless Grip Connectors to make connections after cutting the strip to length if needed. If you are familiar with soldering, you can go ahead and do so to make more permanent connections, but please test your expertise on a small segment of strip before committing to solder your entire project.

Q: Which Power Supply do I need for my (x) feet of LEDs?

The length of LED strip lights of your project will determine the size of the power supply you need. View our Power Supply chart to find the exact LED power supply you need.

Q: What is CRI and TLCI and why should I care?

Color rendering index (CRI) measures how colors are correctly rendered under a light source in comparison to natural sunlight. The index is measured on a 0-100 scale with 100 being a perfect rating of color accuracy, meaning the colors appear as they naturally would under unadulterated daylight. High CRI lighting is sought out everywhere, but is particularly valuable in. The bottom line: the higher the CRI, the higher quality is the light source.

95 - 100 →  Phenomenal color rendering. Colors appear as they should, subtle tones pop out and are accented, skin tones look beautiful, art comes alive, backsplashes and paint shows it's true beautiful full saturation. You have to see it to believe it! 

90 - 95 → Great color rendering! Almost all colors 'pop' and are easily distinguishable. Noticeably great lighting starts at a CRI of 90.

80 - 90 → Good color rendering, where most colors are rendered well. You may not see items as fully saturated as you would like, but most people will not notice.

60 - 75 → Poor color rendering. Items and colors may look desaturated, drab, and at times unidentifiable (cannot see the difference between black and navy colored socks).

Q: What are lumens (lm)?

This is a quantifiable amount of light produced by an LED strip or other light-producing product, as seen by the human eye. In other words, this is one way we can measure how much light is produced. When comparing LED strip lights, you want to compare the lumen output as well as the CRI, watts/foot, warranty, and bin selection.

Q: What is the maximum run length of the UltraBright™ Sienna Dim-to-Warm Series before voltage drop?

The maximum continuous line of lighting in series is 16 ft (5 m). Longer connections are possible in parallel with the correct power unit.

Q: Can I cut the strips myself?

Yes, our LED strip lights are made to be cut to your desired length. Using sharp scissors, you can cut this strip every 3 3/8". You’ll see the cut marks printed on the surface of the strip.

Q: What is the importance of UL Listed?

The Underwriters Laboratories (UL) are an independent, not-for-profit organization that focuses on evaluating products for safety certification. This means you can use and install these LEDs in commercial spaces, industrial applications and in your home knowing that these are safe products.
