Does any one know if XP-G leds will work well through XR-E optics?
XPG with XRE optics?

Depends on the exact configuration. I had an excellent result upgrading an old Silverpoint light:

The resulting beam was much brighter (I would estimate around 130 Lumens as opposed to 60-80 with the old emitter) and very smooth. This was quite a heavily OP reflector though, so was basically a floody beam to start with.
Might be different with a tightly focused reflector - I would imagine you might lose a bit of throw.

OK - perhaps you can be a little bit more specific about what you are trying to do ?

I don't want to go into detail, but I have access to a multi emitter optic designed for XR-E leds. I want to build something more powerful, so XP-Gs came to mind. I am curious if the XP-Gs would look decent through an optic designed for an XR-E.
While we are on the subject, is there a different high output emitter I should consider that would be compatible with the XR-E optic?

The xp-g R5 should be the brightest to work with xr-e optics.
According to this post, an xp-g was used with the TIR optic and it was mentioned that the LED would need to be raised a bit to focus properly but it seems to work fine.

the bezel isn't screwed down all the way and is loose. so does that compromise the seal and security of the front end? I have seen an XP-G in a SF TIR optic. Its a wider beam than the original, more floodier so its not really "working" per se to put more light into the same beam pattern as it has with the original LED.
for those that really want the tight beam pattern the TLS Turbohead or the Dereelight Turboheads with the proper reflector for the XP-G that Dereelight has is working to make a nice tight beam. I did a video on that last night.

MrGman, I may be wrong but I understood DeFABRICATA's post to mean that if the xp-g were taken off the board then it would focus w/o unscrewing the bezel.
Regardless, I haven't had any first hand experience with an xp-g and TIR optic so I will defer to your experience.

right but the LED is still on the board and taking it off would be bad for it, needs a thermal cooling path. So your compromising something to get somewhat better focusing, its just not the optimal condition and it still won't be as tight of a beam as the XR-E regardless.
I am sure that there will be optics to come out for this die type since it will be very popular based on the fact that its capable of 300 out the front lumens.
I would love to see some one simply make a 4 degree beam pattern optic(with some spill) for an LED light that doesn't involve a big fat aspheric lense hanging out the front. Maybe 6 degrees at max.
The SF TIR optic that I looked at last night with the XP-G behind it was a fairly fat beam and wasn't really worthy of making a video of as it wasn't really better than the XP-G inside of the P60 reflector, not enough to get excited about.

Stick with an XRE...overdrive it a bit if you can- it will be plenty bright!

Ok, that makes sense, thanks for clarifying.
Ah yes, even thought the Integrated Sphere is gone, the backyard of truth will remain. Your Youtube vids have been great showing real world shots! Thanks!:thumbsup:
