Fluorescent illumination is based off of using electrodes inside of glass tubes to first ionize an inert gas, which in turn excites electrons in Mercury atoms. These excited electrons then release photons that excite a phosphor coating on the inside of the glass tube, which is ultimately responsible for the wavelengths of light put out by the particular fluorescent bulb.
Cool, compact, and economical, Fluorescent Illumination provides flicker-free lighting with consistent color temperature. White bulbs, specific color bulbs, and black (UV) bulbs are readily interchangeable for different applications. Long lifetimes and low profiles make fluorescent illumination a great choice for industrial as well as microscopy applications. Optional black bulbs are very useful for UV inspection and UV curing applications.
