For sale is my S21A which I have turned into a very high powered Luxeon V 4000K triple. The tint is lovely, much nicer than the XPL or SST20. The full specs are as follows:
- Convoy S21A host (either green or grey, I can swap it over).
- 3 x Luxeon V 4000K emitters.
- Led4Power high performance MosX MCPCB with low resistance FET and temperature sensor installed.
- Led4power LD-B4 driver with many programmable modes, current limits, shortcuts etc. It also uses an external FET on the MCPCB to keep heat away from sensitive parts.
- Solid copper spacer made by Kiriba-ru, soldered directly to the pill for optimum heat transfer.
- Carclo triple optic.
- Bypassed springs.
I don’t have anything to measure the output with but I gather you can expect at least 5000 lumens from a build such as this. It’s currently in a slightly scratched grey host but I can swap it over to a basically pristine (it’s been in my pocket a couple of times) green host if you like.
I’m asking £60 but I might be open to offers. This is quite a special light that I’ve put a lot of work into.
UK only. Ideally pickup/delivery in London, if not I can post it.
