One embodiment of the present invention includes a portable electrical illumination system and an optically opaque hollow module, configured to releasably couple to the portable electrical illumination system in a manner such that when the portable electrical illumination system is activated, the system produces a discrete correlated or focused illumination output. The portable electrical illumination system further includes a light emitting diode, a power source, a switch, and a coupling mechanism. The optically opaque hollow module further includes at least two openings, a hollow internal region, an optically opaque outer surface, and a coupling mechanism disposed on at least one of the at least two openings. A fourth embodiment relates creating an adjustable aperture between two optically opaque sleeves sliding over an optically transparent module coupled to the portable electrical illumination system.
