LED Neon Flex – Features, Benefits & Uses – Professional Guide

LED neon flex has become the backbone of most modern forms of lighting and signage—and this is by no means an exhaustive list. As you might presume from the name, LED neon flex is flexible LED strips. These can be used in many different applications beyond just signage so that I will explain all of the features, benefits, and uses of LED neon flex.

  • Able to be daisy-chained so that lengths can be joined together
  • Moldable into almost any shape, 2D or 3D
  • Available in fixed color, RGB color, and Dynamic Neon
  • Useful for making signage, artwork, and in general lighting applications

This is what LED neon flex looks like – 7 color examples – white, red, pink, blue, green, yellow, and warm white.

LED neon flex is an LED strip light encased in a plastic tube. Its heart is its ability to emulate the classic glow of traditional glass neon.

Here is an overview of its capabilities:

  • Energy-Efficient: Uses significantly less energy, making it an eco-friendly solution.
  • Advanced Visual Capabilities: Available in static, RGB, and animated variants.
  • Customizable: It can be molded into almost any shape (either 2D or 3D) or design you can imagine. The only technical limitation is a bending radius of 2″ to perform a U-bend.
  • Durable: Not only waterproof and UV light resistant but also boasts a long lifespan of up to 40,000 to 80,000 light hours, making it ideal for indoor and outdoor applications.
  • Consistent Lighting: Superior brightness and an evenly diffused light that eliminates hot spots and dots.
  • Safe and Toxin-Free: Neon Flex operates without toxic materials like mercury, in stark contrast to traditional glass neon signage.

Technical Composition & Functionality

The heart of LED neon flex lies in its circuit board, which dictates the light’s capabilities. Depending on the circuit board used, it can:

  • Display a single, static color for a consistent ambiance.
  • You can change the colors to suit different themes or occasions, and for those who desire a full spectrum of colors, RGB and dynamic Flex are options.
  • Create dynamic visual effects, such as chasing lights, enhancing the vibrancy of any space. These features are possible due to the sophisticated design of the circuit board embedded within the LED neon flex.
  • It is cuttable only at designated cutting units, ensuring that modifications do not affect the overall functionality.
  • Neon flex lighting has a specific bending radius (2″ for U-bend) that must be adhered to to prevent breakage. This allows for significant malleability while maintaining the strip’s integrity.
  • Color control to set the desired hue.
  • Brightness adjustments are fully dimmable for the perfect intensity.
  • Color temperature settings for warm or cool lighting effects.

Benefits: LED Flex vs Traditional Glass Neon

Let’s compare LED Flex to traditional neon lighting and find out which is the superior lighting product.

Here are the key advantages that LED Flex offers:

  • Energy Efficiency: LED flex lights consume significantly less power than traditional neon, which translates to substantial cost savings. This equates to about 80% less energy.
  • Lifespan and Durability: It has a lifespan of between 40,000 and 80,000 hours, outlasting traditional neon lighting by a factor of three.
  • Weatherproofing: Capable of working in extreme weather conditions, unlike the glass tubes of traditional neon.
  • Eco-Friendly: Traditional neon light signage uses mercury and rare gases. LEDs are simpler and require no rare Earth minerals or hazardous materials (more facts about neon).
  • Ease of Installation: Easy to install – once made, everything the sign needs is included in the parcel and can be plugged into an outlet and work immediately.
  • Design Flexibility: The flexibility of LED neon flex means creating custom neon signs is far easier, quicker, and cheaper. The added bonus is that they are available in 24 colors (which is more than traditional neon).
  • Low Heat Emission: LED lights produce little heat, making them safer than their vintage counterparts.
  • Control: LED neon signs typically have remote controls for brightness and color-changing or programmable features.

Ideas, Applications & Uses

One of the most appealing aspects of LED neon flex is that it can be molded into complex (or simple) neon sculptures, artwork, or signs.

Here are some ideas on how you can use it:

Signage and Advertising

Businesses can create eye-catching, visually appealing, and energy-efficient signs.

Architectural & Decor

Using neon flex lighting in architecture transforms indoor and outdoor spaces into visually stunning environments.

  • Building facades are illuminated with neon flex lighting, highlighting architectural features and improving curb appeal.
  • Used to create ambient lighting in homes, adding warmth and character to living spaces.
  • Another useful application is our outdoor and landscape lighting, both of which can have commercial or domestic applications.
  • Kitchens, bathrooms, and living spaces where strip lights can be used in semi-hidden or recessed applications.

Event and Special Occasions

LED neon flex lights bring a unique touch to special events, making them memorable and photogenic.

  • Weddings and birthday parties are adorned with customized lighting designs.
  • Special events benefit from the dynamic and safe lighting options (Prom nights, bah mitzvah, etc).

Creative and Artistic Designs

The advanced capabilities of Neon Flex allow for innovative design applications that go beyond traditional lighting.

  • Art installations come to life with dynamic colors and flexibility, providing artists with a new medium to express their creativity.
  • Home decor is elevated with personalized designs.

Custom Neon Signs – Options & Features

One aspect we’ve touched on is how customizable LED neon flex is and how it offers an unparalleled ability to sculpt and craft a neon sign that suits specific design requirements.

Here are some of the ways it can be customized to suit:

  • Design: 2D, 3D shapes or a standard flat backboard; this can be whatever you wish.
  • Colors: Choose from a range of 24 colors, which can closely match brands or themes.
  • Sizing: With sizes ranging from 6″ to 3000″ (and beyond), a custom neon sign can be crafted to any size.
  • Backboard Print: We have unlimited color options if we UV-print the backboard. This process can also be used to print an exact design in detail (like a logo or artistic design).
  • Backboard Cut: We can also cut the backboard to any style you wish (close cut, letter cut, or rectangle).
  • Indoors/Outdoors: Neon signs can be tailored to suit indoor or outdoor usage.
  • Mounting/Hanging: We have several mounting options, such as wall mounting, hanging, or even desk stands.
  • Dynamic & RGB Option: With the RGB color range, we can use a specific type of LED light to allow multi-color control and options. Dynamic neon is programmable and more advanced, allowing for complex patterns of colors.

What is LED neon flex light?

  • LED neon flex is a form of flexible strip lighting that consists of multiple Light-Emitting Diodes (LED) arranged in a circuit and affixed to a strip. The term ‘flex’ highlights that these LEDs are attached to a flexible strip, allowing them to bend and curve, unlike traditional lighting on a rigid structure.

Is there a superior lighting technology to LED?

  • Laser diodes are emerging as a superior lighting technology to LED in several ways. They are significantly smaller and more efficient, capable of emitting up to 1,000 times more light while consuming only two-thirds of the energy required. This efficiency could allow a single laser diode to illuminate an entire house.

How long does LED neon flex last?

  • The lifespan of LED neon flex is quite extensive, with each LED (and there are thousands) within the tubing capable of lasting between 40,000 to 80,000 hours. This equates to about 15 years of regular usage.

Can you cut neon flex?

  • You can cut neon flex. Expert designers and manufacturers cut neon flex to the right lengths, use terminators, and properly seal the strip. LED Flex uses 12v power, which makes it safe to cut and needs very little terminating, unlike 110v or 240v power supplies without step-down devices.

Can you bend neon flex?

  • Neon flex can be bent. Its bend radius is about 2″, meaning it can be bent 180 degrees, a U-turn, every 2″ of space. This is a technical limitation of Neon Flex.

Is Neon Flex waterproof?

  • Yes, Neon Flex is waterproof. If attached to a board, the attachments need to have silicone sealing to prevent water exposure.
