Sorry, but while it’s great it was no problem for you, this is NOT representative of everyone. This is the insidious nature of COVID. Some people experience minimal symptoms while others have more grave ones. Vaccinations do a great job of helping patients survive. But you know, the vaccination rate has dropped in the USA. People are more apt to go by their own “seeing is believing,” either their experience of COVID or by others in their orbit. It’s a logical fallacy to conclude that this is representative for everyone else. People are letting their guards down, which degrades efforts to expunge the virus from society.

You do know that getting vaccination won’t prevent transmission in any way and then there is huge list of side effects.
Also I would recommend seeing Phizer EU hearings. Are you still trusting that old narrative?

To preface this, I believe in science and vaccines that have been around for decades. But I had both Pfizer’s and a booster and still caught the ‘Rona and was sick for over a week. How can anyone know the long term side effects of a brand new medication that had limited testing?

I trust the scientific process, but I don’t trust pharmaceutical companies to act in our best interests. There’s too much money at stake.

This is a nice conversation.

Hey, can one of you guys recommend an 18500 battery for the DW4? The 18350 is awesome but the light is hard to hold because it’s so small

I’m going crazy thinking about all the different combinations of the mirrors I can get when I buy more of these bad boys. I think the next one will be a combination of emitters to give me great tint ramping, and maybe the one after that I’ll have a thrower or maybe a monochromatic blue. And I’m definitely going to get one with all ultraviolet emitters

Actually while I’m asking… what is the best 18350 and best 18650?

Vapcell INR18500 K15 for output current (15A).

Panasonic NCR18500A for capacity (not sure if it can run a DW4 with only 3A).

I wouldn’t get anything besides the Panny 18500….and if you want it protected for whatever reason, Keeppower has them under their label as the P1850C3. I picked up a pair of them at Illumn but I think Aloft Hobbies had some, and Liion and a couple other stores seemed to be out of stock forever. I’d be hesitant to order these from aliexpress. The china cells all seem to be crud for this size but I’ve never owned any of them myself.

18350…I’ve got the Vapcell green F14 3A 1400mAh (it’s a tad less than that) for a little higher capacity in some lights and the Keeppower UH1835P 10A 1200mAh for others (not sure what’s in the Keeppower but it’s a really capable cell with great capacity for the drain).

I don’t know how the 18500 would fare in that light…should be well enough but if you are fond of turbo or running for longer periods of time it might fall flat a little bit. The Pannys are good cells, though.

18650…Sony VTC6 or Samsung 30Q or the Molicell similar ones are great. If you usually stay out of turbo or use it for shorter periods where the voltage can bounce back up, the 35E and similar higher mAh cells might get you a little more run time overall. If you run the 35E and such at higher currents often, the actual capacity will often be a washout where you might as well get the higher drain lower capacity 30Q instead.

Yes of course. Vaccination won’t prevent you from catching COVID, nor does it act as a reliable barrier to stop transmission. But symptomatic people can be more transmissible than those who aren’t. If the vaccine minimizes symptoms then it’s helping to cut down some transmission.
Keeping in mind about disinfo and politically related inferences not tolerated here, note that all vaccines have some side effects. And yes, some people can have bad reactions. That’s the reality for any vaccine. I’ve had side effects with every vaccine I’ve gotten. Just feeling low energy, tired, body aches, and on my 2nd inoculation I stayed in bed for a day. Within 24~36 hours, totally fine. No lingering symptoms. No worse than a flu shot. I haven’t gotten COVID. My housemate got it. Two members of my family (who I don’t live with) got it. I’ve socialized with people who had it and recovered. I’ve been generally good about popping on a mask when in close quarters in public, except for restaurants with anti-viral ventilation systems.

OK, ‘nuff said. I don’t have anything more to add. Thank you.

I’ve bought from 18650BatteryStore, Illumn, and BatteryJunction. I don’t know what’s going on with shipping, but some sites are charging outrageous shipping fees for batteries now. I was looking to get a few cells and while preparing to check out at Illumn and preparing for a $7~8 charge, it was $16. Same at LiionWholesale. JLHawaii808 seems to have better pricing. But, they don’t have a few cells of interest.

Hi Hank,

Do you have any indication on how the current lockdown will affect your shipping and for how long? I hope all is well for you personally.

Our area has been in lockdown since Oct. 28, it is said that the lockdown will last another week. I’m sorry for the delay, the exsiting orders will be shipped as soon as the lockdown is over.

Hi, the lock down in my area is over, we will start to send the exsiting orders tomorrow, thanks for your patience.

Glad to hear you can move and operate with freedom again. Won’t it be nice someday if covid evolves into something less concerning/contagious? I remember what that used to be like. lol Smile

Yes! 


Last email exchange with Hank I asked the same question, and...
"Yes, there will be D4K Ti+Copper version in the future."  
But no ETA at the moment.  
 

It's available

hey hank, is the SWITCH RETAINING RING in the D4K Ti screw in, and only one height?  From that picture I can't tell if it flat, or raised.

Hi, yes, it’s screwed in, the switch is a bit recessed in the head.

Hi Hank,

Is it possible to buy an aluminium D4K with a threaded switch retaining ring like the D4KTi has?

I believe, it's not a anodisation, but fiber laser.

Colors are nice but you can’t beat brass or copper.

Re: D4KTI

Since titanium has worse thermal heat dissipation than aluminum, would it make more sense to add the boost driver here?

I bought the aluminum D4K with the boost driver add-on. Compared to the FET driver, the maximum output is lower. On the other hand, the output is better regulated. Is there any chance to increase the maximum current? I think someone mentioned 2A per LED as the default current.

Does anybody know what kind of sustained output a KR1 gets with 70.3 HI? And has anybody been able to measure the duv of theirs?

It depends of the colour and Cri of the 70.3 Hi LED … i measured the Lumen of my D1v2 (almost same like KR1 but with sideswitch) in the first second in Turbo as follows:

D1  XHP70.3 Hi 70Cri3000k

3230

D1XHP70.3 Hi 90Cri4000k   2380
D1 XHP70.3 Hi 90Cri5000k2560
D1  GT FC403000k2080
D1 SBT90.25700k5320
