The UK SL4 Sunlight eLED L1 UV Torch is an ultraviolet light producing torch so you can see another level of amazing patterns on marine life that you can't see normally. Compounds inside marine life react to certain wavelengths outside our visual spectrum and fluoresce so we can see them. No Filter RequiredMany UV lights require a yellow filter to be worn over your mask or camera but the SL4 uses a specific wavelength that doesn't require any filters to be used. This blue 395nm light sits just outside the visual spectrum so you can see the fluorescence but your eyes cannot see the blue light from the torch.
