Part 1：

A. This series products are made of SMD module, SMD strip or SMD font light. The principle of using the light source is determined according to the font type and the order quantity.

B. The surface brightness is highly consistent, and the luminance difference between different positions of the same illuminated plane is within 10%.
C. Surface light flux up to 20000Lux or higher.
D. The minimum letter height can reach 3cm, and the minimum luminous stroke is 1mm.
E. Using safety voltage 6V or 12V.

F. Can select the new imported PMMA raw materials or domestic new acrylic materials.

Part 2：

A. Illuminated letters with the highest waterproof grade, up to IP68 standard, completely sealed structure, can be completely used outdoors or in 50 meters of deep water.

B. The surface brightness is highly consistent, and the luminance difference between different positions of the same illuminated plane is within 10%.

C. Surface light flux up to 20000Lux.

D. Use the highest destructive resistance LED light source. Each product is tested for aging and electrical properties for more than 48 hours to ensure its reliability for outdoors.

E. Using safety voltage 6V or 12V.

F. Use the new imported PMMA raw materials to ensure that the color of the acrylic will not fade completely within 2 years and there will be no obvious color change in 5 years.
