Choosing the right LED for SF mod

[foxtrot824]

I've just purchased an old style KL1 (ribbed) head and want to upgrade the LED and possibly the driver to be brighter. I plan on using the same optics it came with, Fraen optics I believe. I am looking for suggestions on what a good replacement would be, something that has at least 100 lumens of out put and would still fit. Thanks in advance.

The old KL1 uses a NX-01 optic. A SSC P4 would be your best choice but the NX-01 doesn't work that great with the NX-01 but it's not bad.

Be sure to unscrew the bezel first, remove, the optic, & unsolder the wires before unscrewing the second half to access the driver. If you don't you'll rip the wires off the board. I would remove the emitter heatsink our of the head before unscrewing the bottom half but you can do it without removing it if your careful.

I would leave the driver alone and swap the LED for an SSC-P4. The stock optic is OK, but I'd replace it with a smooth reflector like you can get from Photonfanatic. I have one of these oldies but goodies KL1 with a VO bin Seoul and is still one of my favorite go-to lights around the house.

Thank you all for the advice. I was wanting to keep the stock optics because I like its throw and I want to avoid a floody beam like that of the KL4. Are there smooth reflectors that will still give a tight beam?
