I got the 719a 2700k and Lume driver. The CCT is lower than 2700k, somebody on reddit measured theirs at 2450k and slightly rosy. It's a very beautiful and vintage-feeling color. The efficiency is amazing, I was really surprised at how good the battery life is. I put DC-fix on it for a super smooth beam and it's perfect.

Great addition to my collection as always great product from an awesome retailer will always recommend Jackson’s lights thank you JL!!!!!!

Jackson is a pleasure to purchase from

Love the kr1 now have one in sft42r and sft40 3000k i wanted a warmer cct and wanted this host and just wow final product is exactly what i expected. Jackson is great i have 5 lights from him! Will always recommend Jackson to others

These are my favorite emitters. Not just the FFL351A, but the ~3500-4200K range and just ludicrously rosy. Power handling and efficiency are also decent, and despite the rosy wash, they're still high CRI. I've been swapping these into everything; Convoys, Emisar/Noctigons, even Fireflies with tints I didn't care for. Next up is a Reylight Dawn. I cannot recommend these enough!

Fantastic emitter, this the best place to grab them; not only do you support an awesome business, but Jackson takes the time to bin these emitters, so you actually know what you're going to get. The variability in CCT and tint is the weakest point of these and the sister-emitter that is the FFL351A, otherwise, they're the best out there for a dome-less 3535 emitter right now. For fans of negative DUV, get some, swap out those old SST-20's, XPG2's, hell even 219's with green tint, and breathe some new life into an old light.

This is a great light in a compact package. Please note, for the one I received it worked fine with a rechargeable lithium ion 14500, but it did not function properly with a standard AA Energizer Lithium disposable.

I recently ordered a DA1K with a 6500K SFT70 and a clear lens for maximum lumens in a small lightweight package. I’m using it for long sightlines along a shoreline and along country roads, and it provides extraordinary brightness and throw in a well-focused well-colored beam. Its utilitarian - rather than tactical - design and layout make it easy and convenient to operate and do not impose penalties involving weight or sharp edges. I can carry mine easily in a coat or pants pocket. Also, on the lowest setting, it’s a great light for moving around at home at night with the lights off. This flashlight is a worthy successor to the old Fenix PD35, the BLF-1, and some of the great flashlights from Four Sevens.

Great battery insane power with kr1aa

Just received mine and love how small it is!! Also dealing with Jackson is like dealing with a close friend his customer service is second to none . He is awesome and his products are of great quality I will always buy from him great job Jackson thank you!!!!!

JL is fantastic, got a question shoot him a text, fast to reply. With an outstanding product. Consistently delivering the magic of illumination. Thank you!

I ordered an original D4 years ago, and decided to step up to a full custom. Jackson did not disappoint. If my old D4 is a pocket rocket, this thing is a pocket cannon.

Love it.

Outstanding little light, Hank has done it again- and my custom FFL 5000k was cleanly installed by Jackson. I love this little light!

Very happy with this light. Fast shipping too.
