Similar but oddly shaped

1 Thank

I like the idea of putting a TIR lens in this. Are there any 23 × 12 mm TIR optics that may fit? It looks like the only Convoy option is 23.3mm x 13.5mm, which I’m sure can be made to fit. Maybe something without the white plastic holder though?

I’m pretty sure this one without the holder should fit without much fiddling

Nice. What emitter would you use with it?

1 Thank

Most likely 531 or maybe even 73B

2 Thanks

you can take off the plastic holder, or just cut the lower part if the outer circumference is needed to fit the host
Cheers​:flashlight:

@Toaster79 Nice. I am thinking of building one with lhp531 4000k. I’ll play around with tir optics. Maybe 15° flat?

I’ve always had good luck with the beaded TIRs but YMMV.

M4C build. SFP55 5500k. Did this driver build the other night… @INeedMoreLumens 32mm Fet+1 driver on Oshpark After Dark coloration, with Anduril 2.

I left the emitter wire long for now, as this will go through some changes, so I wanted extra for the time being.
ETA: I used 16ga wire in this build.

This is one of my favorite DDH hosts at the moment.

I had 15° beaded in S21E with 531 and it was great flooder. Then switched to 10° flat and it was still great but with a pronounced hotspot. Still a great flooder
