Features of 3-LED CCT Tunable White LED Light Module
1. 2700K–6500K Tunable White CCT
The YS-MD8331-TW 3-LED CCT Tunable White LED Module combines 2700K warm white and 6500K cool white LEDs in one module, allowing the overall white appearance to be adjusted according to the needs of the illuminated sign. This gives designers more flexibility than using a fixed-CCT LED module.
2. 160° Wide-Angle Optical Lens
A 160° beam angle provides broad light distribution inside the sign cavity and helps spread illumination across translucent faces. The wide optical design is especially useful in illuminated letters and light boxes where a balanced appearance is required across the visible surface.
3. Flexible 8–18cm Signage Application Range
The product is recommended for 8–18cm deep signs, including channel letters, metal letters, light boxes and decorative illuminated structures. The additional depth range compared with the standard MD8331 white version gives this CCT model broader flexibility for different sign constructions.
4. Individually Cuttable Module
A single module can be cut as required, giving installers more flexibility when adapting the lighting layout to different letter shapes and sign dimensions.

Recommended Applications for 3-LED CCT Tunable White LED Light Module
1. Channel Letters with Adjustable White Appearance
The YS-MD8331-TW 3-LED Tunable White Sign Module is ideal for channel letters where the desired white appearance may change according to the brand, environment or time of day. The 2700K–6500K range gives the finished sign more visual flexibility than a fixed-color module.
2. Light Boxes with Variable White Requirements
For 8–18cm deep light boxes, the module allows the white appearance to be adjusted after installation through a suitable CCT control system. This can be useful when the sign must coordinate with different graphics, face materials or surrounding lighting.
3. Day-to-Night Illuminated Signs
A tunable-white sign can be adjusted according to ambient conditions. A warmer setting can create a softer evening appearance, while a cooler setting can provide a brighter visual character during daytime operation.
