I went out to see if I could capture some shots of just how impressive the WA01318 bulb on 4.5SF123s is. The reference is the RadioShack KPR112 on 3SF123s. In both cases, the WA01318 is on top. First photo, the back of my garage from about 45'. Same exposure for both subshots. Second photo, the front of my garage, about 25', same exposure. The digipics are from the video mode of my digicamcorder so they aren't the greatest. The hotspot looks positively incendiary in the photos but that is an artifact of the exposure setting. The spots were bright, but details and artifacts were discernible by eye.
You can see the two-lobe shape of the WA bulb hotspot. This is due mostly to the size of the filament. To its credit, the KPR112 has a very small filament that images a rounder spot.
The pictures don't tell the whole story. This bulb on 4.5 lithiums (4x123 + 1AA) throws a meaty, very bright beam and the secondary spill is easily brighter than my Lamba Illuminator AdPro. The color is yellowish of course, but it easily puts down my V3U-bin 5W Mag 2D.
