Jaxman has some nice 219B high CRI options:
For a bit of a thrower

The only thing I don’t like about their UI is the SOS and strobe.
Those are truly impressive! Especially at that price point; pretty hard to resist. Unfortunately, I’m hoping to have a light one week from today (for a trip). I’m still planning on ordering one of those, however. So thank you!!
The only other Nichia flashlight that takes an 18650 that I could find is the Astrolux S41, and you have to separately get the 18650 body tube.
PFlexPro has a great line of flashlights and offers Nichia 219B emitters in many of them that are within your budget. The line also includes a Solarforce L2P with a Nichia emitter that is just a little over your budget.
pflexpro is a BLF member. IMO he does great work and is very accessible. I think you could message him here with any questions.
[EDIT] the user interface on those lights is quite nice.
That Mini C8 with 219 looks absolutely delicious. Thanks!
The Mini C8 is a pretty wonderful light! My kids use it as much as I do. It has a little throw and really good spill, really a nice mix and it is compact.
Here is my build thread.
What country are you in?
If you think you are up for soldering two wires and unscrewing a pill. Then it is very easy to mod a light to take a Nichia.
Assuming you are in the USA.
Get yourself a Convoy S2+ (the S2+ is nice and floody, the S2 a little less floody, but will so the same thing).

$16.99
These are really nice lights, well made, high quality. But sensible price.
And buy a Nichia LED:

$4.59
It’s really easy to do. Unscrew the torch as though you are putting a new battery in.
Look inside the head:
See the two holes, use some tweezers, circlip pliers or something to unscrew it. This is the pill, the side shown in the pic is the driver. But no need to do anything with it for now. Turn it over once it’s out and you’ll see the LED mounted on a star (like the Nichia above).
All you do is de-solder the positive and negative wires. Put some thermal paste on the back of your new star with the Nichia on. Put it in place and solder the two wires. Then assemble.
Very very easy. Even for a first time doing all of it, it should only take you 20 mins ± from start to finish. And you’ll end up with a nice Nichia torch.
If you’ve not soldered before, it’s really easy.
Video here on how to solder:
Good advice CD, but I feel obligated to point out that’s a picture of the switch/tailcap side. The driver/pill side will look slightly different. (instructions still the same)
Put a piece of Scotch “Magic” (gray frosted) tape over the lens as a diffuser
Or you can get somewhat thicker diffuser material

lol and well spotted. I just pulled the pic from MtnElec and I didn’t see one for the driver… 
You are probably looking for a 18650 light. But EagleTac D25C nichia on Illumn is a great deal and a great CR123/16340 light at $30. I have the Ti version and loved it.

I recommend Manker E14/ Astrolux S41. cuz it has so many options with lumens level and nice hidden features too. Not only that with 18650 tube (need to buy separate less than USD 4) you may get longer run. Keep that in mind it need IMR batteries to get all of the light. NCR18650GA or LG HG2 recommended. Be careful if you are planning to light-paint longer time using High 1 or High 2 because its get really really hot.
Keep in mind if you order directly from them here, for the E2, they put a note that they can make a version with just low-medium-high with no strobe if you want. Just put it in the “remarks” section.
I wish I had know about this when I ordered it from a third party vendor.
I have the Manker E14 and I have been very happy with it. I did buy the 1860 tube from Banggood but I mostly leave it in the 18350 configuration as I like the small size. When hunting season starts I will want the longer run times but for my day to day use I like the smaller size.
There is a good breakdown in post #48 of this thread that is worth a look:

ALL OF THEM
Wasn’t impressed with the jaxman at all . the output is very underwhelming the driver is stone-age stupid compared to whats out there these days and the tints are not visually nice like you want a high cri light to be . the 4000k is lame imho …If people try it i’d understand why they’d shy away from neutrals and call them yellow or green or …Blah !
The 5700 K isn’t a tint i’d suggest either but i’m betting it’s a little better …my advice is avoid both and get a 4500 or 5000k nichia emitter on copper and swap it out .
Mountain Electronics also carries a very nice P60 drop in, the CUXM/CUXP, that is available with a Nichia 219B. It’s about $20 USD with shipping, I assume within the US.
If you don’t have a P60 host, they carry them as well. The only caveat is that the drop in is designed for one Li-Ion cell. Any more than that, or two or more CR123s, and poof!, there goes the Magic Blue Smoke.
Thanks for this! I live in the USA. I’m thinking this is the best option. Floody, cheap, small, and the correct battery type. Plus I have no problem soldering, I’ve done it plenty of times! Thanks again!
I put one in a Convoy M1 host and it makes a nice little light.
