Meh.
I wouldn’t be too hopeful, as most drop-ins tend to be cheap and stoopit. Ie, just the LED on a disc (not even any thermal goo), and the “driver” is the contact-board and a few parallelled chip-resistors to get some random amount of current through it. Forget about LVP or anything “smart”. At least having some 7135s helps, as they crap out with too-low voltage at a certain point and won’t keep draining the cell.
I got 2 types from FT, an UF and a no-name. They were okay, but nothing special. Think I kept the emitters but ditched the drivers. Been a long while…
If you don’t mind soldering, get the 17mm driver of your choice (plenty of 1-mode donks) and the LED you like (1A is too blue for me), and roll yer own.

is a nice one, and I use ’em often.
Get an OP or SMO reflector (or both; see which you like better), just solder up 1 pill, and you can swap reflectors to suit your mood.
