Yup! Done that, I posted to What Did You Mod Today, though I’m not quite sure it counts as a mod!
Not sure if this works:
I really like the blue GITD and the blue anodising on the switch retaining ring. Took a few goes to get the tape in perfectly.
The blue GITD tape charges better with higher CCT light, this photo is roughly what I see with my eyes immediately after switching the light off, in daylight conditions. To stage this photo, I shone a LW UV lamp at the TIR!
