Flexfire LEDs Dynamic Tunable White lighting

Our UltraBright™ Architectural Dynamic Tunable White Series LED strip light can be adjusted to produce very specific shades of white. This strip light is not only fully dimmable, but allows you to control the color temperature (shade of white) with the touch of a remote! We manufactured this strip with LEDs of alternating color on the circuit board so that half of the LEDs are a lower temperature and half are a higher color temperature. This means you can select the perfect color of white using a remote control, DMX system, 0-10V system, or our smartphone app.
It is the perfect lighting solution for projects that require a specific shade of white or the ability to change the shade of white over time. The UltraBright™ Architectural Dynamic Tunable White Series is available in ranges including but not limited to 2400K-3000K, 2700K-4200K, and 2700K-6200K. See the below image to visualize the color ranges available.

Why choose Dynamic Tunable White LED strip lights? 

Full control over specific CCT (shades of white)
These Dynamic Tunable lights give you full control over what specific shade of white you want at any time. You no longer have to worry about finding the exact replacement to match with existing lighting colors. You can match existing lighting that is in the same area by using the remote to change the LED strip's CCT setting until you find the perfect match. Set, then forget!

For your health
Lighting is not only important in its function of general illumination and brightness. Lighting color, purity, and CCT can affect our emotions, health, and sleep patterns. High CCTs like the midday sun help us stay awake and focused. However, at night, our circadian rhythm (internal clock) can be interrupted by our constant use of high CCT man-made lighting (think about using your bright phone screen at night in bed). Disruptions in this rhythm can result in health issues such as obesity, cardiovascular and neurological problems like sleep disorders. Researchers have found that CCTs above 5500K (containing a high amount of blue light) can disrupt our circadian rhythm by keeping us up when we should naturally be sleeping. 

Tunable white LED lighting enables us to return to our natural circadian rhythm by giving us that range of lighting in either our homes or in the workplace. In the daytime when you need to focus, you can change the lighting to 6000K while in the evening before bed, you can decrease the CCT to 2700K, promoting the natural release of melatonin to help you sleep.

Set the mood
Lighting and emotion goes hand in hand. The ability to control your bedroom lighting from a functional 4200K during the morning/mid-afternoon to a calming 2700K will not only help you sleep better, it will turn your bedroom into a place you love to relax in again. High-end hotels have been using this technology for years to better the experiences of their clients in their temporary homes. Bars and restaurants love this feature to be able to change ambiance as the sun goes down.

UltraBright™ LED strip light FAQs

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.

What is the product warranty? 
We’re so happy with the quality of our product, we offer a 15-year warranty on most of our LED strips to all of our clients. The warranty on power supplies ranges from 2 to 7 years which is model dependent.

What is the lifespan of your strip lights?
Our lights have been rigorously tested and have an expected lifespan of 50,000 hours before dropping to 70% luminosity. This means that if you were to use your lights 12 hours a day, every day, the lights would be expected to last longer than 10 years. Even after that time has elapsed, the lights will maintain a brightness of 70%. Higher-output strips require a heat sink to reach the expected lifespan and beyond.

What is color temperature?
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 is noticeably warmer. On the other end of the spectrum, the lights have a blue-ish tint and cooler tone when rising above 6500K.

Which color temperature should I choose?
Choosing the correct color temperature range for the Dynamic series lights is very important. Consider the look and feel you want your project to have. What other color lights will be present? What material and color are the materials you wish to light? We can help you choose.

What are lumens (lm)?
This is a quantifiable amount of light produced by an LED strip or other light-producing product. This is one way we can measure light output.

What is the maximum run length of the UltraBright™ Architectural Series lights before voltage drop?
Maximum continuous string of lighting in series: 32ft 10in (10m). Longer connections are possible in parallel with the correct power unit.

I am looking at the UltraBright™ Architectural Dynamic Tunable White series for task lighting in my kitchen, but I am unsure which will be better, the 12V ColorBright Dynamic Tunable White Series or the 24V Architectural Series?
The 24V Architectural Dynamic Tunable White Series is the best strip to use for larger projects that require a high level of lighting. Every environment is different so please feel free to contact our design team for further recommendations. The 12V ColorBright Dynamic Tunable White Series is another excellent option that offers accent lighting with a lower intensity at an average of 177 lumens per foot. This option works well for smaller areas that also require task lighting.

Is there an outdoor option?
No, we currently do not carry the outdoor version of this strip but if you would like us to stock this product in the future, let us know!

What do I need to turn on my lights?
To turn on these LED strips, you will need to connect them to a low voltage power supply and a Dynamic Tunable White compatible controller. For Dynamic Tunable White LED strips we recommend using our solderless connectors. If you are skillful at the art of soldering you can do so for more permanent connections, but please test your expertise on a small segment of strip before committing to solder your entire project.

How do I mount the lights?
The 3M double sided adhesive that is found on the back of the LED strip allows you to install them in most locations. Be sure to thoroughly clean the surface to remove all dust and particulate matter before mounting the strip. Certain surfaces may require you to take additional measures to secure the strips lights into place. Feel free to call us with any questions.

Can I cut the strips myself?
Yes, LED strips are made to be cut to your desired length. Using sharp scissors, you can cut this strip every 4” inches. You’ll see the cut marks printed on the surface of the strip.

What is a 3014 SMD LED chip?
3014 SMD (Surface Mounted Diode) represents the size of the LED chips on the strip. A 3014 SMD chip measures at 3.0mm x 1.4mm. Click here for more information on LED chip sizes.

What is the importance of UL Listed?
UL is an acronym for the Underwriters Laboratories. They are an independent product safety certification organization. A good summary used by UL is, "a not-for-profit organization dedicated to public safety." This means you can install these LEDs in commercial spaces, industrial applications, and in your home with peace of mind.
