A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

A lighting apparatus includes light emitting elements having an emission peak wavelength of 400 to 510 nm, a first phosphor having an emission peak wavelength of 485 to 700 nm, a second phosphor having an emission peak wavelength of 510 to 590 nm, a third phosphor having an emission peak wavelength of 600 to 700 nm, and a color filter having transmittance for light with a wavelength of 600 to 730 nm that is 80% or more and transmittance for light with a wavelength of 410 to 480 nm that is 3% or more and 50% or less. The color filter transmits a part of light emitted from the first phosphor, at least a part of light emitted from the second phosphor, and at least a part of light emitted from the third phosphor. Light transmitted through the color filter is emitted to the outside.

A Light Modifying Device adapted for use for photography. The Light Modifying Device is a generally bendable and durable tear-resistant material comprising of two surface faces comprising a plurality of irregularly shaped openings for receiving light therein. The Light Modifying Device can be positioned in a variety of locations and additionally manipulated by way of bending such that a portion of light may be diffused in one location in a photography set and enhanced or otherwise differently diffused on a different, second particular location of the same photography set.
