Yup... what greenLED said (although I found it easier using a small alcohol "candle" and tweezers to heat n' pick the epoxy away). And a double "YUP" in regards to being super careful around the inductor - they are very delicate!
cratz2 - yes, since the Nichia CS is cousin to the original BS in the Infinities, the beam and spill is all there... with almost twice the intensity. Amazing output for a little 5mm LED. Puts an Opalec Newbeam to shame. A CS in a regular (i.e. - dim) Infinity gives almost as much output as a stock Ultra.
I'd also recommend polishing the reflector while apart - as it significantly increases the hotspot's size and intensity. If you leave the LED's two O-rings off when re-installing the board, you can extend the protrusion of the LED in the reflector a mm or two - and gain a little more hotspot "oomph" there as well - even "tune" it's size/brightness by varying the depth. I then used putty to temporarily seal around the LED when re-potting the circuit with epoxy.
The Nichias are slightly tapered (smaller diameter near their rounded tip, than at their base), so you may have to countersink the bezel's LED hole from the circuit side, to allow inserting the LED far enough to seat its shoulder against the head's interior. Just a small depth needs to be removed - with a drill bit the next size larger than the LED's dia., just above it's shoulder.
mykall - runtime is the same. From what I understand, the old BS and the newer CS are virtually identical - except for some kind of trick die technology that allows almost twice the light to escape the diode junction (someone correct me if wrong).
Worthwhile mod, definitely!
