I’m offering for sale the Zebralight SC64c LE with a Nichia 219B R9080 for $150 USD plus shipping. I first posted about this mod back in September 2018, and I’ve since completed well over a hundred lights. I have Nichia 219B R9080 in sw30, sw35, sw40, and sw45k, and a nice FA3 bin of SST-20 in 4000K. I can also install any compatible 3V LED with XP style pads that can be sourced, so if you happen to want a different CCT we can almost certainly arrange something.
H1 output with sw35, sw40, and sw45k is approximately 445 lumens, 470 lumens, and 505 lumens, respectively. Mode spacing on the sw45k light I tested is 0.01, 0.09, 0.39, 1.2, 3.7, 10.3, 26.2, 58, 115, 205, 334, and 505 lumens. Since the 219B is a relatively small LED, the beam with a clear lens will be more narrow than stock (much like the old SC62d), with 143m throw for the sw45k version. I include pre-cut d-c fix that can be applied to the lens if desired, which diffuses the beam and lowers sw45k output to ~465 lumens and 104m throw.
Here is a tint comparison of the sw35, stock 4000K XP-L2 EasyWhite, and sw45k (left to right). As you can see the stock LED is rather unpleasantly green as maukka discovered in his review, and it also has a fairly poor R9 value at higher outputs.
Please send me a PM with your LED and lens preference if you’re interested in purchasing one of these lights.
