Are the Lights On? You'll Know with LumiTest
The LumiTest is both a light probe and a contrast indicator. Its emits a tone that increases in pitch as light is approached. When the LumiTest is in direct contact with materials, lighter colors are indicated by a higher pitched tone. Users can easily tell whether lights are on, locate a light source in a room, tell whether an LED is solid or flashing, determine whether a page has print on it, and find the blank space on a letter to write their signature. 90-day limited warranty.
