LED neon flex is a silicone-encased LED strip that produces a continuous, diffused glow similar to traditional neon tube lighting — without the fragility, heat, or noise. It's fully flexible, durable, and available in CCT-adjustable versions that shift between colour temperatures. Lumily's FLOW range comes in 13mm and 19mm profiles, CCT adjustable, in black and white finishes.
Where it works best
Ceiling coves and coffers: Neon flex's rounded cross-section gives a more even light distribution within a cove than a flat strip, producing a softer, more architectural glow.
Architectural recesses and reveals: Horizontal reveals in walls, door frames, and joinery detailing take on a different quality lit with neon flex rather than a standard strip.
Commercial and hospitality: Bar fronts, counter edges, display case frames — neon flex's flexibility lets it follow curved surfaces that a rigid profile can't accommodate.
FLOW 13mm vs 19mm
FLOW 13mm is the more compact option — suited to tighter coves and architectural details where a slim profile matters. FLOW 19mm gives a more substantial light output and suits larger coves and commercial applications better. The black silicone finish reads as almost invisible when unlit against dark or timber surfaces.
