An apparatus for subjecting light sensitive materials to visible radiation is disclosed which minimizes the amount of heat generated. The apparatus includes a source of visible radiation including at least one microwave energy responsive sulfur bulb and applies microwave energy to the sulfur bulb to cause the sulfur bulb to emit visible light. The apparatus further includes a holder defining a surface for receiving light sensitive materials located relative to the microwave energy responsive sulfur bulb. A light diffusing assembly is disposed relative to the sulfur bulb and responsive to the visible light emitted by the sulfur bulb to illuminate light sensitive materials received by the holder with diffused uniform visible light.
