Architectural Dome Neon Flex
Rounded-dome LED neon flex with a nominal 270° illuminated surface, horizontal bending and continuous architectural contours. Configure single color, RGB, RGBW, tunable white, SPI or DMX pixel lighting for custom installations.
A luminous dome.
Designed for architectural curves.
A rounded 270° luminous surface.
The raised light-emitting dome creates a continuous neon-style outline that stays visually prominent around curved building edges and decorative details. The 270° figure describes the luminous surface, not the photometric beam angle.
Six ways to control the line.
Specify steady single-color light, adjustable tunable white, RGB/RGBW color mixing, SPI pixels or DMX-addressable runs. Electrical platforms vary by controller, power and wiring.
Horizontal bending for curved layouts.
Plan arcs, illuminated handrails and sculptural contours using the specified horizontal bending direction. The minimum bend diameter is configuration-dependent: 80 or 120 mm.
Compatible terminations and mounting.
Factory-molded entry connectors, end caps and compatible mounting details support straight, side and bottom-entry installations. Select suitable sealed assemblies for wet locations.
One dome profile.
Six light-output families.
Single Color · CV / CC
5–15 W/m · 12–48V DC

Rated power and permitted feed length depend on the selected electrical configuration. A 20 m carton or 10 m retail box is a shipment length, not an electrical circuit length.

Frequently asked questions.
What does a 270° luminous surface mean?
The rounded dome has a nominal illuminated surface spanning approximately 270° around the profile. This describes the visible light-emitting enclosure; actual candela distribution is shown in the photometric curves.
How are voltage and control configurations selected?
F2121 has multiple electrical platforms: 12, 24, 36 and 48V DC are available on specific variants. Single color, RGB, RGBW, tunable white, SPI and DMX pixel systems require matching controllers, drivers and cable design.
What is the minimum bending diameter?
The product bends horizontally. A minimum bending diameter of 80 mm or 120 mm is specified depending on the selected configuration. Confirm the exact bending requirement when detailing the mounting route.
What is the difference between carton length and electrical run length?
A paper reel contains 20 m of product, while each white box contains 10 m. Permitted electrical feed lengths vary by platform; 48V single-color and RGB options can support longer runs than several 12V and 24V versions.
