# NB-R25

[Home](https://ledyi.com/) › [LED Neon Flex](https://ledyi.com/led-neon-flex) › [Black Neon](https://ledyi.com/led-neon-flex/black-neon) › NB-R25

Black-body 360° round IP65 silicone LED neon flex with a 25 mm diameter.

## Overview

NB-R25 is a round silicone LED neon flex profile with a black silicone body and a 25 mm diameter that emits through 360° with no shadow, for DC 24 V input in published single-color, tunable-white, RGB and RGBW configurations at 5 W or 10 W per metre. Switched off, the black body reads as a dark line and blends into dark facades, joinery and signage. The integrated-extrusion silicone housing is rated IP65 with resistance to salt, acids, alkalis, UV and fire.

Each row is one sellable configuration; one code template may cover several power variants. Reading the code: C = constant voltage, CC = constant current; x = color temperature (Kelvin ÷ 100, so C30 = 3000 K) or a fixed-color letter (r / g / b / y / p / o); a = adjustable white; the x in rgbwx is the white channel's color temperature; on DMX and SPI versions the tail (e.g. UCS512C1L-8P) is the IC model. Example: NS-S1220V24-C30-B = 3000 K, constant voltage.
