I got a Nichia 219c from mtn today, I was going to put it in an Eagletac D25C TI but I figured I’d end up tearing a good light up. So…I decided to put it into one of my A6s, not that they are not good lights, they are just easier to get into, lol. I took the XP-L with 1A tint out, put heavier gauge wire on the driver and slung the 219c in. At first, I used a protected cell that only puts out a max of 10a and it worked out fine, just wasn’t bright enough…so…I put an Efest 35a in it and she ran on all modes without a hitch. I really like the tint of this light. It does get a little hot though. I’ll check amps and all the modes tomorrow and post back. Here’s a few pics of a “Dale Double Spring Bypass” 1A vs. 219c. All in order from level 1 to 7.
