I ordered a Green SST20 4000K w/ regular optics and a gray deep red w/ floody optics because I’m going to use it mostly in my bedroom. Already have a 6500K in black.
Hank, would it be possible to get the D4V2 with E21A flashed with Andúril 2.0 or is the new Andúril available for K9.3 only? I just placed another order.
As always when buying new amazing flashlights from your shop: Resistance is futile. $)
Nice! Please post some beam shots of that deep red. And I vote cyan w2, because that’ll be my next light lol. So I guess I’m being partial. But having a 4000k and 2700k seem to me to be … I don’t know to similar . I mean I know they’re very different but why have lights so close when you could have a 4000k beauty tint and w2 hotrod Tiny thrower! Plus, it to mention buying the w2 from Hank is like $50 cheaper then getting it from Vinh (I think Vinh is awesome) just saying though
Received mine today. Amazing speed for just the basic non-express, put order in on 1/09. The lights are awesome. The KR1 is as heavy as you would expect, little over 12 oz with the battery- and my does it throw well. It’s also got some good spill as well. The K9.3 with the 2000K and 6500K is exactly the contrasting look I was wanting. I would say the 6500K SST20s in the 3 surrounds has more output than the 9 E21A 2000K leds but what a nice warm glow. The SST20s give mostly flood with the optic but still reach out much more than the warm whites. I got the warm white switch on this light, I like it not yellow just med dim incan white color.
I am not aware of any new spicy options unfortunately.
It seems, that no more XP-L HI 2850K 90CRI available - I was wondering, that I will maybe get one, but eventually I missed that.
A D4SV2 with 9A maximum current driver would be nice, because it could use the Osram CSLNM1 FY (Yellow) emitter, but it didn’t happen yet.
All in all, D4SV2 is now restocked, and we got:
- +5$ base price
+5$ price in extra options (if I remember it right, SST-20 Deep Red and Osram were affected)
So I wonder, if the restocked D4SV2 is better in any regards, or this is just a price bump (e.g. $54.98 -> $64.98 for the SST-20 Deep Red).
So, for you Photon Master, I can only suggest SST-20 2700K, because it will collect less insects during summertime nights (but this is most spectacular with the E21A 2000K vs any other white LEDs), and it is the best tint after E21A for that CCT (very nice at lower currents).
Thanks. That’s correct w2. I have a d1s with the w1 so I knew what that’s like- and it’s really good, really good throw. But I just wanted to try something different. This seems to have about 95% of the throw but with a fair bit more overall output.
Thanks guys, I love the E21A 2000K too. I have that as CH1 on one of my 9.3’s and also my KR4 Ti-Copper. That soft golden light is beautiful. Unfortunately Hank said he can’t do E21A 2000K for the D4SV2 or the D18 which would be wicked
I also thought of doing a monochromatic XP-E2 but when I asked Hank, he said that he can do it but not for the D4S V2 and D18, since the driver does not support it
Still not sure which emitter I want to in the Cyan to complete my D4SV2 collection.
I actually don’t have any D4V2’s and he has E21A’s for those. I’ve never seen the E21A 3500K, 4000K, or 5000K
E21A 3500K R9080 has a gorgeous tint. If you like 2000K you will certainly love 3500K as well. I have it in a KR4 and it’s just awesome.
I have just asked Hank what kind of driver he uses for D4Sv2 with Osram W2 and SST20-DR. He said it‘s the FET+1+3 driver. I agree the 9A CC circuit would be a nice choice for that.
D4v2 or KR4 with monochromatic XP-E2 LEDs? Great idea. Hank could probably sell a lot of them with the 5A CC driver, running them at very reasonable 1.25A per LED. I bet XP-E2 red 620nm would be much brighter compared to SST20-DR. I still love the better red tint, though.
I wish Hank offered a series version of the multicolor D4v2 (RGBW) with MELD UI. :LOVE:
Unfortunately, I did not find the time until today to have a closer look at my K9.3 flashlight. I only put it out of the box into my shelf when it arrived. I wish I had looked at it closer a bit earlier. On the other hand, what I complain about is most likely quite nitpicky and functionality is fully given. I admit this is not a $ 1000 Oveready BOSS light but for a $ 144.48 flashlight I would still have expected less imperfections.
What I like:
It works to my satisfaction, well almost. I chose XP-L HI 4000K V2 5D for CH1 and SST20-DR for CH2 as well as a red switch backlight. The light came on in CH2 (deep red) and Advanced UI with stepless ramping. It puts a very decent big spot of light onto the wall. Deep red is quite bright on full power.
What could be investigated a bit more:
When K9.3 is on lowest brightness (FLOOR) those 9 XP-L HI emitters start to flicker like crazy, looking like candle mode is activated. Turbo mode for CH2 in combination with SST20-DR seems more or less useless as another doubleclick will immediately bring brightness down to CEILING level again. I am talking about 0.5 or maybe 1 second for stepping down. Thermal stepdown is programmed to 55°C and the K9.3 was still at room temperature. Maybe Hank can have a deeper look into this as I hope this is normal behaviour and that my K9.3 works flawlessly.
Something that took me by surprise:
The head has a significant notch, probably abrasion from CNC machining. It could not be caused by myself as you can see it's black anodized. Again, nothing serious but still it diminishes the otherwise nice look and feel. The stainless steel bezel shows some scratches right out of the box and a rusty mark where it touches the head unit.
Someone must have written something on the head unit. I can just about recognize "S7R R" written on it with some permanent marker pen. Certainly, this is nothing to rant about as I could clean it off with a cotton swab and alcohol. But still it's a bit confusing to see this on the outside of a flashlight. The black dot in the left section of the switch button is somehow distracting from the great red glow of the backlight, like a fly on the wall. ;-) I hope my second K9.3 that is en route already will have less imperfections.
After playing with the K9.3 for a while I discovered a software glitch in Andúril 2.0 that is maybe important to mention. The Lockout mode will be left automatically if you set the AUX lights to Beacon/Blinking. Fortunately, in most situations this is not a serious bug but still it can lead to unpleasant situations wearing it in your pocket and feeling certain to have locked the light before. I highly recommend ToyKeeper and Hank to have a look at it unless my K9.3 is affected only. Maybe some of you can reconfirm this glitch.
I made a video to demonstrate the software glitch:
I made following observations with the faulty AUX Beacon mode:
1. Go to Lockout Mode (4C from OFF)
2. Select Beacon AUX (7C via off - low - high - beacon/blinking)
Red Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
I feel your pain, I recently received some lights which had some blemishes out the box. Not significant enough to raise it but still enough to take the shine out of what I consider a more premium product.
Apart from the imperfections I am wondering how to deal with the flickering on FLOOR level. I could set a higher FLOOR level but then again, where's the point in having "moonlight" if it's not really low? I also wonder about those three SST20-DR stepping down immediately. The light will not even get warm on the head, so it can't be a thermal stepdown on the driver. :???: I hope the other K9.3 (CH1 E21A 2000K, CH2 SST20 4000K) will be/work better.
Linear driver + low Vf leds : SST20-DR has a Vf arround 1.6V at 3A according to the datasheet, let’s say that a charged cell drops to 3.8V at 9A, you’re dissipating (3.8-1.6)x9= 19.8W in the mosfet(s), which is enormous and the temp sensor in the MCU will pick that heat very quickly (thankfully because otherwise the mosfet would probably blow). Increasing thermal dissipation could maybe help (slightly), adding a thermal pad between the mosfet(s) and the body for example.
