These small, unbelievably bright micro-flashlights are available in a spectrum of colors and perfect for a variety of experiments and student applications. Although MicroLights are not lasers, and therefore not monochromatic, they come extremely close with their ultra-high intensity LEDs to a specific wavelength (except, of course, for white). Available in red, orange, yellow, green, blue, violet and white. Violet, with wavelength of 405 nm (see chart for other wavelengths), is close enough to the UVA spectrum to excite fluorescent minerals or even hidden fluorescent dyes on currency and credit cards. Replaceable lithium batteries included! Each light fits easily on a key chain. Demonstrate Einstein's photoelectric effect using various colors and a square of our Phosphorescent Vinyl (see item SM-7). Don't miss our Assortment Pack- a full set of seven at a huge savings!
