I think this is one of the real attractions of the "covert" models of the Photon line. At least 95 percent of the time, I don't need the light being diffused to the sides anyway, so I don't think "clear" is essential.<br><br>I don't think the heat needed to shrink the tubing would bother the electronic components, but you might have to be careful of the case and LED depending on how you do it.<br><br>Barry at Blue Line mentioned (in an e-mail) that he'd found some black rubber grommets/washers in a hardware store that were a friction fit over the LED, and protected it.
