Re: PT Eos Headlamp + ims17 reflector + cree x-re
Not too bad. If you want a smoother beam a drilled out McR18 gives an outstanding beam from an XR-E.
Was that the optimal focal point for the IMS?

probably sanded 3-4 mm off the bottom of the reflector. bought the eos pre-modded with a ROXH and the ims17. It was pretty good before, but the useful spill is much greater with the cree.

Hi Pumaman,
Nice mod. It even seems that I would be able to do that. Anyway, it is clearly worth trying it. So I just ordered some Crees... and hopefully I will make my first "mod"
What sort of runtime do you get with that mod?

Re: PT Eos Headlamp + ims17 reflector + cree x-re
update.
decided to try the mcr17xr reflector from the sandwich shoppe. Had to file off about 3 mm off the front to fit it in the eos. Taking that much off the front gives the reflector a little bit of the famous dark ring in the beam, but not enought to affect real-world use. and as you can see its much better than the ims17. now a beautiful, bright beam in a compact headlamp:rock:
eos on left, HDS B42 on high on right.

Runtime will be the same, as the current has not changed - just the efficiency of the emitter. You get more brightness at the same runtime.

There is no additional heat sinking from the factory, so you get the same thing with the replacement. You just get more light. They do get hot on high, and we guess that's what the temp sensor is for - to back off the current at a certain temp.
Anyone have a hankering to try this mod with a Q5 Cree? I sure am. 
Is there any better reflector to use than the mcr17xr reflector?
I guess spending time sanding it down isn't too terribly horrible. That way I can be sure it is a tight fit, unlike the loosey goosey IMS17.

Did you use the black plastic optic/reflector holder at all? Or did you just tape it like in the pic and let the pressure hold it when enclosed?

just used the tape and pressure. felt pretty secure.

If my Q5's ever arrive, I DO think I'll get that hankering to toss one into this thing with a Mcr17xr. Can't wait... though I have to....
