Penetray 100W PAR38 Blue Incandecsent Reflector Lamp - Lit Up

Here is the vintage Penetray Blue PAR38 turned on. Notice how some warm white light gets out the edge of the bulb's front, as the blue coating is only on the very front. The lamp has a narrowish flood or wideish spot beam pattern that is actually pretty even. It gets tighter at lower brightness levels. Shown at 100% and 50% brightness in this image.
