KC1 keychain light is available now

Hank - Can the K1 driver for the W1 be changed to get higher amps for the green W1?

I'd like to set it for at least 6, as high as 7 amps. I reviewed and asked bout it here: https://budgetlightforum.com/t/-/59694/605

Doesn't seem do-able from firmware, so assume it's a resistor mod, if safe/possible to do so.

Is there any update regarding the deep carrying clip for the KR4?

I just received my latest order from Hank. I like warm light, but I have to say that I did not expect E21A 2700K R9080 to be this magical.

Colors look perfect, and it does not look like a typical 2700K led at all. It looks pure white on a white wall, there is no trace of yellow. Even SST-20 2700K JA3, which is known to be below BBL, looks a little bit yellow. At first I was sure that I actually received E21A 3500K R9080 by mistake. Only after comparing it directly to SST-20 2700K JA3 was I able to convince myself that it really is 2700K.

I now have D4V2 flashlights with these warm emitters:

  • E21A 2000K R9050 (received today)
  • E21A 2200K R9050
  • E21A 2700K R9080 (received today)
  • SST-20 2700K JA3
  • XP-L HI 2850K T6 8B (received today)

I still like all of them, but E21A 2700K R9080 is by far the best. There is no comparison. I have Lee Zircon 802 and 803 minus green filters, but even with a filter none of the other leds look magical like this one does. Perhaps Lee Zircon filters are not suitable for very warm leds, I do not know. I use E21A 2200K R9050 with a Lee Zircon 803 filter, and it does make it look a little bit better.

I suspect the reason E21A 2700K R9080 looks the best is that it has the highest R9 and the lowest DUV of them all. R9 makes a lot of difference. You should definitely get it if you like warm light.

Thank you for this! I am new to this and have been torn about which one of the e21 emitters to get my next Hank light in. Awesome input!

Guess I should have chosen expedited shipping. My order placed 10 days ago has not shipped yet. :person_facepalming:

You know…… China has been on holiday since the first of October till the 8th so pretty much everything came to a close till festivities ended….

I saw that on BG or AE as well. hard to wait though :sunglasses:

XP-E2 Amber makes E21A 2000K R9050 look like a standard 2700K incandescent light bulb with perfect color rendering.

Beamshot: E21A 2000K R9050 vs XP-E2 Amber.

It has gone quiet :frowning: which is helping me save/plan for the perfect KR4 :sunglasses:

The new clip is already under production, it should be available within this month.

You should definitely get one in 4500K. I have a few Nichia 291B sw45k (also 4500K) emitters, which were being already praised for being a nice neutral tint, but in my opinion, that is too rosy, and even looks a bit rusty compared to E21A 4500K.

E21A 4500K is simply the best high power neutral tint, you can get currently. It is about perfect.

By the way, I am also expecting back 3500K into the available tint list, which is again a very good tint.

Awesome, thank you! really appreciate the input :smiley: :+1:

Got my shipping notice yesterday

Any pictures of what the clip looks like? or drawing?

I was disappointed in my d4v2 2700k. It seemed greenish. It could be because this chart shows its duv being higher than the others; right on the bbl while the others are below it. However, i then swapped it for 3000k and didn’t like that either. The warm ones may just be too ochre. Next will be 2000+3500.

I concur that e21a 4500k is the best tint so far. That’s definitely the one to buy now, but when 3500k returns that will give people more options.

I’ve modded two of these new emisars and consider it easy. The hardest part is getting the 6 wires back through the center of the mcpcb afterwords, but they can be pulled out and pushed back in to make this easier. There’s a lot of extra room on them. You also need to solder the main wires cleanly so that the aux board fits back in (duh).

Yes, pics of the clip please!

Side Note - I used a propane torch, 6’ vise and small hammer to straighten and re-bend my kr4 clip into a deep carry. It came out… as a deep carry. kind’ve off center and tarnished (the heat destroyed the polished look) but it worked great! i can share a picture if anyone’s interested.

Problem is, the heat weakened the metal and it broke, a couple of times. I fixed the break 2x but now its not worth it. I am debating doing it to my kr1 clip but i don’t have another clip backup after that.

Cant wait for the REAL deep carry to arrive in the store!

E21A, R9080, 3500K in stock.

I have KR4 E21A in both 4500k and 3500k. Could not pick between them, would be like picking a favorite child. 3500k beautiful warm rosy tint. 4500k extremely “clean”, neutral, rosy but not overly pink like sw45k. These are my 2 most carried lights by far at the moment. Buy both if funds allow!!

Dammit… now I’m really doing this… already have the gray kr4… guess it’ll be black and cyan. Oh whoa is me LOL

Thanks :partying_face:

Could not resist, ordered a D4V2.
