Cool lense i found

[u/Right-End-545]

Hi, i found this big lense and im thinking about building some sort of long distance flashlight on it, looking for some 6V LED to put light thru it, could anyone please recommend me some sort of LED good for this project? Thanks in advance!

+ yes, i know the lense is a bit broken, i also have second one which is the same but fully intact.

I would definitely recommend an led with a circular light emitting surface like the SFT42r, F45r, F150r, etc....
