Pretty decent. Tight fit.
I went for 3x white LED's with a 100 ohm resistor. I actually wanted to use a 60 ohm resistor, as that would still work and get me a bit extra light. My LED's were not diffused, but thought it would look nicer, so I scuffed them up with some grit 200 sand paper.
I used some simple 2-wire connectors - I have a bunch and had previously run 2x 2wire connectors to my hot-end. As well as created my own plug & play hotend connector
Anyway, it looks pretty decent - more than bright enough. If I get time I'll scuff up the LED's a bit more to flatten out the light.
Had to do a tiny bit of cleanup where the cover snaps into the base - it over extruded by the tiniest amount
