The BlueLine Model FL5000 is a revolutionary new flashlight for fluorescent NDT inspection. It works with existing fluorescent particles and penetrants and does the job that you are used to doing with high powered UV lights, but does it with much more convenience and safety. The intense blue light excites the fluorescence of the materials, and the BlueLine filter glasses completely block the reflected blue so that you see your fluorescent indications with maximum contrast. The unique flashing mode makes it much easier to see indications when there is ambient light present.
