I am really enjoying my KR4 and although I do like the standard 18650 size the 18350 tube is a must have in my opinion. If you use the better quality 18350 batteries the quad set up of the KR4 becomes a palm sized reliable powerhouse. For the price the 18350 tube should be considered a must have buy for anyone considering the KR4.

D4Sv2 with FFL emitters (FFL351A in 3700k), perfect as always. The only place you can get Hanks with FFL emitters!

Ch1: FFL351A 1800K ROSY BIN
Ch2: NTG35 4200K

Jackson's builds always bring a smile to my face. This one is an instant favorite. I satin etched the lens to give it a frosted appearance and smooth the beams out. If you're weighing the decision to get one or not, just do it. I always wonder why I waited so long. Doooo it! ←⁠(⁠>⁠▽⁠<⁠)⁠ﾉ

I have hundreds of lights and have been very involved with anything light related for years. I recently discovered this dealer and must say the latest KR4 purchased here is simply amazing. I really like the customization offered and the quad set up with 18350 tube is a perfect combination. I am already planning my second purchase. Also if you are in the U.S. shipping is crazy fast.

Awesome work. Jackson fixed my screw up, where a bad reflow job on my part may have killed my Lume X1 driver. He reflowed the MCPCB, replaced the driver, and got it all back together looking as good or maybe even better than when I received it from Hank. Highly recommend this service for repair or other swaps.

Great product with very fast shipping!

I messaged through the chat support and actually got to speak to a person instead of AI!!! Amazing! JL answered all of my questions, so I ordered with confidence.

Love the fit and function of the new parts for my edc light

D4K antique copper perfect fit. As always.

I am on the road for work and haven’t installed them yet but they are perfectly manufactured

Jackson runs a tight ship. Reached out to me via text to confirm something I forgot to order. Even sent pics for comparison. He makes it easy to do business with.

Nice to see this here, don't have to hunt one down on the r/flashlight BST post. Without getting into custom PCBs or machined components, this is a nice step up in flashlight modding beyond emitter swaps and the like. Highly recommend the 3D printed case for this as well.

Made a mistake choosing option on my light and got an email within minutes clarifieing my order and helped me select better options! BEAUTIFUL LIGHT! And unbelievably fast shipping! Will ABSOLUTELY be buying again.
Thanks!

Looks awesome, pairs very well with Hank's blue-grey. I was a little too early to the "paint it black" party, so very thankful that so many of these parts are available here.

Even better it works.
