Item Type: Light Color Synthesis Material: ABS Model: 25013 Uses: Used in optical physics experiments Experimental Power Supply: DC6V (power supply is not included) Working Current: 0.3A 1,A better learning instrument, this instrument can make students understand the three primary colors more intuitively. 2,The teaching is more vivid and can be adjusted in three light colors, which is more intuitive. 3,The design is more convenient to use and convenient for teachers in classroom experiment teaching. 4,Rugged and durable, made of ABS material, long service life. 5,It is a good physical instrument suitable for the experiment of light synthesis of three primary colors.1. In order to have a better experiment effect, please reduce the brightness of the surrounding environment light. It is best to experiment in a darker environment. 2. The instrument should be kept in a dry, ventilated, cool, and non corrosive place. 3. The instrument should not be subjected to heavy pressure and should not be dropped to avoid damage.1 x Light Color Synthesis
