Commonly used fluorescent tube (
Or with a reflector)
As the blackboard lamp use, form the top of the blackboard is too light, easy to tell the students not clear blackboard upper white FenBiZi blackboard writing, and lower part is too dark, the lack of intensity of illumination, students can't read write content.
