Black-body side-bend IP67 silicone LED neon flex in a 12 mm by 20 mm profile.

## Overview

NB-S1220 is a side-bend silicone LED neon flex profile with a black silicone body, a 12 mm by 20 mm cross section, DC 24 V input, and published single-color, tunable-white, RGB and RGBW configurations. The strip bends horizontally in the mounting plane while the emitting face keeps facing the viewer; switched off, the black body reads as a dark line and blends into dark facades, joinery and signage. The integrated-extrusion Dow SILASTIC ET-7021 silicone housing provides high strength with IP67 resistance to salt solution, acids, alkalis and UV.

## Configurations

| # | Code Template | Input | Power | Drive | Protocol | Outputs |
| --- | --- | --- | --- | --- | --- | --- |
| 1 | NB-S1220V24-CCx-E | DC 24 V | 10 W/m | CC | — | White 2700K–6500K, 6 fixed colors |
| 2 | NB-S1220V24-Ca-E | DC 24 V | 10 W/m | CV | — | White 2700K–6500K |
| 3 | NB-S1220V24-Crgb-E | DC 24 V | 10 W/m | CV | — | 3 fixed colors, RGB |
| 4 | NB-S1220V24-Crgbwx-E | DC 24 V | 15 W/m | CV | — | White 2700K–6500K, 3 fixed colors, RGBW |

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.
