Yes, I think so.
I just ordered one. Will you be updating your other lights with this emitter?
Ordered, Thanks!
Titanium will be awesome, but what about brass?
Yes, will do this in future.
Both brass and Ti are in plan.
Great news
Thanks, ordered.
My Reylight collection is growing fast.
What’s the lumens for each mode and estimated run time for the 10440 and Eneloop Pro?
10440 max 300lumens, 50% is 150 lumens then. 20% is 60 lumens. Math work. 
AAA, max 110 lumens,
My Reylights have excellent mode spacing with Nimh or Lithium Ion.
In your comparison pic, the mini looks patina’d. So this won’t be coated like I heard the regular pineapple is?
Yes, there is no coating at all. Machined, washed, cleaned, assembled, checked and sealed in vaccum wrapping.
This takes one1.5*6mm tritium vial. On eBay, you can get one for $8.87, so paying Rey $7 for one and having it installed is super value add! 
Yes and he does an excellent job!
That’s the one he did on my Pineapple AA/14500
Ordered. My full size Pineapple and twist Mini Pineapple just had a baby. Genetic evolution at it’s finest!
Just when I thought this was the winner over a few others I was looking at, I noticed the pocket clip. 
Any chance of a AA Pineapple type clip?
I really really really want to like this mini pineapple. The clip though.
Sorry.
No worries. No apology is necessary. The tail cap looks like it unscrews. I might be able to add a washer with a loop sticking out so I can put it on a key ring. I am sure I can figure something out.
I still think I need to order one. I love all my Reylights and I don’t think the clip would keep me from ordering it anyway.
Yes, the tail cap can be unscrewed. If you add a washer, the button will get too loose.
