Using Orbtronic 3500 mAH unprotected for the DW4 with E21A emitters

What are you running?

Sanyo or Molicel ?

Other ?

Has anyone compaired this unprotected Orbtronic with the competition

Been using their protected cells for several years now and quite satisfied

I saw that Hank has high power UV emitters. I’m going to see if he can do a D18 with 18 of those bad boys

UV-C ones would be even better

Any luck with getting a D18 with UV emitters? Last I checked with him,
getting one with (18) 5w UV emitters was a no go.

What a pity..(

I wanted to buy a flashlight (DW4), but Paypal supports Ukraine and does not work in Russia.  Could you add another request for payment?!

Geopolitics have certainly taken a turn that harms many uninvolved. If you cannot work out an alternative form of payment perhaps an intermediary can assist.

I noticed there is no 5000K LED options. I would like to ask a couple of questions regarding the LEDs in 5000K range.

1.
I was looking for E21A in 5000K, but I do not see that option anymore. Is E21A 5000K coming back?

2.
I heard 519A can be a better option than E21A, but I only see 5700K and not 5000K.

How does 519A 5700K compare with E21A 5000K in the lights?

Here are some interesting observations I made on E21A and 519A both in 5000K.
a) My KR4 with E21A measures close to 5000K in CCT when measured with Opple Light Master. The measurements did not change much from low to high output.
b) My Covoy light has 519A in 5000K, but CCT measurement are 4400K in low and 4700K in high output.

I just yesterday did some measurements on the 5700K 519A, in the hotspot from a reflector (without lens), stock and with a sliced dome. I will post the numbers tonight, do not have them here, but I can already tell that when used in a reflector, the 519A is not 5700K but somewhere around 5200/5300K (and nicely very close to the BBL, with great CRI and R9).

Thanks for the information.

Indeed my Convoy has an OP reflector. It is Convoy T3 with 13 groups.

I wonder if the consistent measurements across outputs (ranges from 4950K to 5050K) in my KR4 is due to the frosted TIR optic or the E21A. E21A versions of KR4 were equipped with frosted TIR optics.

Or… the difference in LED drivers has to do with the variations of CCT depending on output.

I wonder how 519A 5700K performs in KR4 or D4V2.

Any news ? I ordered on the same day and still no update for me .

My order from 6/2 shipped this morning. I believe that was the day 519a 2700K became available, and not only that but he was allowing people to essentially preorder the LEDs before he received them so I’m sure there was a backlog in addition to many new orders that day.

Going for a headlamp with some throw for walking and flood for indoor and closeup use, and with that sweet rosyness.
My current main headlamp is a Sofirn D25LR which is pretty decent for the price, I use it more than my Acebeam H30 due to the weight and size.

Bold emphasis mine, the DW4 is 83g Vs acebeam 80g. It’s still an excellent light, but I’m slightly disappointed with how it feels as a headlamp (asymmetrical weight).

Edit to add: I can’t find a thread specifically on the DW4, does one exist?

excellent info, Djozz! I'm glad to see Simons sm575 batch looks good to (at or below BBL). Hanks batch (not sure if they're smxx5 or smxx3) already look awesome (I have dedomed 5700k in a dw4 dual channel)

For those like me who are waiting for an Hank order, be advised that his email system was off a few days ago, and it’s possible that your order is shipped without you receiving an email .

If you log into Hanks site, you can check your order status. It is pretty up to date and will also have the tracking number listed if it has been shipped.

A.small note. I got DW4 with 2700/4500K dual channel 519A. I have a few observations.
- The anodizing on the body tube is a bit disappoining. Speckled.bits of missing anodizing in the knurling. Very hard to capture in a picture but probably in a video it’s visible.
- I think the low mode is higher with 519. I have a dual channel 219B and the low mode is okay. The 519 seems a bit higher. Note, I have seen this in other lights I have modded with 519.
- The light is surprisingly a lot longer than the D4v2. That’s a shame.

Otherwise, it is a nice light and will definitely have a spot in my reading rotation. Just a few disappointments.

I got lazy after more than 20 orders never having to check the order screen, only waiting for the email and only then starting to worry .

Are all boost drivers identical or do larger hosts, like D4SV2, allow for larger components to be used (for increased efficiency/superior performance)?

How many amps is the driver set to on the d4v2? With the 519a led?

They’re all the same. 12V 2A or 6V 3.6A, depending on LED selection.

Unless you specify a driver, it will come with a 7135+FET driver. The regulated 7135 channel tops out around 350ma IIRC. The FET channel will probably top out somewhere in the 15-20A range with 519A’s and a high drain battery.

Actually the inductor on the DM11 12V driver looks to be bigger than the on the D4SV2 12V driver: https://budgetlightforum.com/comment/1836577#comment-1836577 vs https://www.reddit.com/r/flashlight/comments/tvkp73/close_up_shots_of_the_12v_driver_hank_uses_in_the/

So it likely has a slightly lower DCR for a slightly better efficiency, although I think I’ve heard they both now use the D4SV2 driver?

Has it been verified that the D4SV2 beet driver and D4V2 boost driver have the same topology? I don’t think I’ve seen a pic of both sides of the D4V2 driver

I’ve used the clips from my Armtek Wizard lights on both my D4’s and even though the fit isn’t exact, they have hung on for years of daily use.

Very deep carry.

Hi, Hank. I’ve ordered DW4 with 519 in May. Some days ago I noticed that my payment has been refunded. Is there something wrong with the shipment? What’s the reason?

I was just suggesting the DW4 with SST-20 660nm to a friend for darkroom use. I’m curious as to why the boost driver can’t be used with those emitters. Vf too low?

The quartet has arrived!

  • Impressions so far: SST-20 DR are extremely red (duh, I know, it’s my first time though).
  • A pleasant surprise is the boost driver’s moonlight (1/150), it’s wavering and fluctuating a bit but overall it gets much lower down than the dual channel linear, almost comparable to PL47G2, the queen of moonlight (out of my collection at least).
  • Headband feels nice, turns out it actually works better for me with the easily removable top strap off. The neverending plight of us planet-headed.
  • Tailcap magnet is hecka strong, the DW4 can hold itself horizontal on a round steel horizontal pipe (wow!).
  • Looks like KR4 clip will work though to make proper contact when installed between tube and head, solder blob or a ring of wire would need to be added onto the driver PCB, same with the tail end, or, more likely, I’ll 3D print a spacer to fit between tail PCB and the cap. Of note is that the KR4 clip will kill tailstanding.
  • Speaking of tailstanding- there is no flat spot opposite the optics so the DW4 will roll and not remain pointing up on its own.
  • The head does not protrude forwards, turns out protruding head is useful in preventing fingers from partially obstructing the optics when handheld, thumb-on-button style.
  • Overall the lights are beautifully built but that’s the standard.

It does work actually, only that the moon mode is just too bright, almost like medium mode, so, you can only ramp from medium to high mode, other than that, it works fine, I assume it’s because of the low VF.

One resistor needs to be changed for the output voltage to swing across the lower voltage range of red LEDs. The current range is about 8.5V to 14.5V (simulated with the resistor values), fine for white LEDs but doesn’t go low enough for red LEDs.

I talked about it in several comments in this Reddit thread

Remember that there is custom firmware to lower the moonlight on dual channel lights. https://budgetlightforum.com/node/80620
