Here you go:
CREE XP-L HI V3 3C LED on Noctigon 16mm MCPCB

Now you need a heat-sink though since you don’t have a flashlight tube…

Thanks for the comment.

That or the XPL – HI seem like 2 pretty good options to look in to. 700 lumen from such a small size sounds phenomenal.
When this thing is made on has good heatsinking, is there anything that you think might cause problems if I put it into an IP67 enclosure? Could it overheat and cause me problems?

I am from Germany I could do it for you.

I would go away from flashlight and build the star on a heatsink and seal the solder joints with acryl or epoxy, then it is IP68, no need to add a case with AR glass and heat problems.

Pretty much the star mounted on a heatsink,
cables to the PSU and buck driver that are in a case.

It is easy to get 700-1000 lumens from a XPL HI on DTP star.
