Description

The SVG "feSpecularLighting" filter in IE11 behaves very differently than the same filter in Chrome and Firefox, as shown in the attachment.

To reproduce the Chrome/Firefox image in IE, one has to use the square root of the original specularConstant and half of the original specularExponent (assuming that lighting-color = white).

Uh, I edited the dead URL to a working one a long time ago. I don't know why you're still seeing the old URL. Anyway, here's the working URL again:
