Great flashlight. No issues and great customer service.

I sent two lights in to Jackson for some switch issues. He installed emitters I requested and the lights were returned better then new and now outperform
any lights I own. Jackson Lee is our go to light source and we make our living with
lights

Tail cap fits fine. Like the ability to have magnetic or non-magnetic cap at my option.

Works great. Nice protection of the delicate components. Did not fit inside the head housing of the KR4, so required a bit of filing to narrow the height of the pin side. Simple fix and now it is perfect.

Awesome 14500 light, smaller than expected, which I really enjoy as it still puts out over 1400lm with the DD 4500k nichia 519a, the tint is a beautiful rosy color. The colored titanium really stands out and the build quality is phenomenal, however, I do have issue with the threads, they could be better, same with the o rings, aside from those though, this is by far my favorite flashlight in my collection. D4v2 coming next.

My D1K arrived flawlessly and promptly. Also, when it turned out that the emitter I ordered quickly ran out of stock, Jackson promptly reached out and helped me pick out another emitter choice.

I have never had any issues with the 3-4 lights I have ordered from Jackson. And I like the FFL emitters that are exclusive to Jackson’s Emisar lights.

First time using Jlhuwaii, absolutely excellent service putting together this host. Very quick communication.
D3aa TiCu with 1x1800k & 2x3700k. Lovely rosey 3250k. Very pleased overall.

Worked perfectly. I backed up flash and eeprom, and then reflashed newest firmware for a KR4 and a D4K. This thing was fun.

I chose SFT-25R (6500K)/FFL351A (3700K) for spot/flood, cold/warm. This is my new favorite and my new EDC. It's the smallest 21700 on the market. The build and shipping is lightening fast.

Fast shipping, great options, informative updates on even the smallest changes. Great packaging, Always a chill experience.

Happy and satisfied.

The titanium host with copper head is absolutely beautiful. Extremely compact for an 18650 flashlight.

I went with the FFL351A 4000K and 1800K combo, it's perfect! The 1800K emitters have a super warm almost reddish desert sunset tint, and the 4000K is clean and slightly rosy. Mixing the two makes for an unbelievably nice super rosy tint.

As always, an awesome build from JL, and got it quickly, I'm very impressed with his builds and his unique emitter selection!

The workmanship as well as the recommended tint were amazing.

These lenses are great especially for your daily driver or if your a little rough on them like me. More light output with no visible tint shift thanks again Jackson

I got the ffl909mx in this bad boy and it’s a rocket for sure! Jackson’s builds are awesome and the many more options of emitters makes my go to Emisars and Noctigons from Jackson. Plus his turnaround time is next level! Customer service is the best I have ever had. Don’t hesitate to order from jlhawaii!!

I wanted a hotrod light and boy did Jackson build it for me! I went with sft25 and holy moly! The absolute WALL of light this thing puts out is insane. Comes with heat but we all know what we’re getting into haha. Plus I went murdered out with color scheme and Jackson has the black no light button covers. Makes a slick complete look. Highly recommend! And I actually pocket carry mine, the flat head actually doesn’t feel any bigger and helps orient the light in my pocket.
