3 volt XHP50.2

Ah beautiful…thank you! I think that one from Cutter is just what I need.

I know you said you liked this light IRA NightWatch 26650 flashlight, with a de-domed SST-40. How about a mini review for a newbie. I have this light with a XHP 70.2 smooth reflector ( I am partial to throwers and cool white). Just kinda wondering how it may compare since it has an OP reflector.
Thanks in advance.

My IRA has a smooth reflector for the de-domed SST-40. I thought I was going to mod it but I haven’t, like it pretty much just how it is, even with the odd UI. I’ll get around to modding it someday probably, usually do. I just like it’s style, the build is solid, neat light with nothing quite like it out there (that I’ve seen) At this point in the game, unique holds a trump card. :wink:

You must know someone there, I sent them a message asking if it was available with a smooth reflector and they said no. I guess that I could order it and then order a separate reflector.

So lets summarize where we are
3 tint bins across 2 flux bins @ Cutter
2 tint bins across 1 flux bin @ Kaidomain
1 tint bin @ ASFlashlights
Anyone tested voltage for J4 vs K2 flux bins or event tint on any of these for that matter? I don’t really trust Kaidomain for obvious reasons.
I assume no changes in dedoming but it would be nice if someone ends up doing it to measure lux and kcd before/after and see how it cleans up the beam. Each bin seems to vary in this respect.
Can this really go in a SMO reflector with no donut?

Check out my pics on the SP70 thread.

I'm confused about the 3B (5400K) version from Cutter - where is it listed in 3V on the Cutter site? Wow, that site is confusing, always was, but now a new look of confusion...

I have no idea how to order them now.

Here is a 50.2 in my L6 with SMO reflector.

Here it is with a lower exposure. You can see the center of the hot spot is a little darker, but it’s not really noticable in the regular pic above.

Same for the 70.2.

It was the older xhp50 and 70 that had the noticable donut hole beam shape.

In the same link as the original post: XHP50B-00-0000-0A00J4051 XHP50 IN 3 VOLT - Cutter Electronics , has listings for 1A, 1D and 3B both as a bare emitter and mounted on boards, but not in any kind of order.

Ahh, ok - guess I was on the right page

This is dome ON right?

Yes, this is the dome on.

I don’t think dome on or dome off makes a difference. Everything just scales down in size. The pattern stays the same. At least for the xhp70 it does. It’s hot spot just got smaller when I sliced it. The light distribution in the hot spot stayed the same.

I imagine the 50.2 or 70.2 have the same light distribution in the hotspot, it just scales down in size. Can anybody here confirm this?

YUCK! :confounded:

Iieewww :frowning:

Wait for the better tints perhaps then. Slicing may help reducing the green corona but the overall tint will get greener, so that does not really help.

Gone are the days when we accepted green when dedoming leds.

I’m sorry for you, I hate green too. That’s why I checked the 3B0 in the datasheet and found out that it will be really green. Despite I like warmer tints, I took 1D. It’s not perfect, it’s cold, but definitely better option that this.

I have not gotten the 3 Volt 50.2 emitter yet to find out first hand , but is the tint about the same as the 6 volt 50.2 emitter in the same Bin/Flux?

If so ……… Are you guys simply slicing the dome off or have you done the “Slice & Dice” method to reduce the Green or Olive that the 50.2 and 70.2 make?

I have had good luck with the 5700K 50.2’s in the past but wanted just a slightly warmer tint , so I tried a 6 volt 50.2 K2 3C / 5000K with the slice and dice and figured it would come out super warm. Although it is somewhat of a warm tint now , surprisingly it is not nearly as warm as I had anticipated it would be once I did the slice and dice.

I have also done a number of the 70.2 emitters with pretty good results getting rid of the Olive or Green with the slice and dice method.

For those who are wondering or haven’t seen the “dicing” part of the sliced emitters , you simply cut straight down beside the actual die after the dome is off and get rid of the phosphor that is around the die itself , which in turn gets rid of pretty much all of the green tint from the flip chip emitters …. just be very careful that you don’t nick the edge of the phosphor on the die itself or you will have a Blueish or light Purple ring around the hotspot. (Yes I know this from my first ever attempt at the dicing part of it…lol)

Here is a picture of the 70.2 in my ThruNite TC20 after it was sliced and diced ……….

And here is what the beam looked like before on a White Garage door (medium mode)………

And the same light and same emitter , only with the slice and dice done……….

Not the best picture of the emitter but , here is the sliced and diced 50.2 K2 3C / 5000K , that I put in 1 of my Maxtoch 2X a few weeks ago….

And what the sliced/diced 5000K 50.2 looks like out in the field by my house at 175 yards from the trees (No leaves yet on the trees in the picture)…….
(I don’t have any white wall shots of this one but I could get a couple if needed for reference)

Sliced & Diced 1 and De-domed 1 3v 50.2’s so far, got 10 more to go! I Dropped the de-domed (it was just about perfect one little tiny piece of silicone left on it) on the FLOOR, guess how it landed :cry: , sliced and diced work good and then it started to burn on the Rock, it is soaking now in some Toluene.

Now I’m just checking the different tints and going for out-put, so I’ll pull 2 of the 5400’s and slap 2 6200 1D’s on the Q8 and offset the crap, might be nice, never know… :smiley:

Here are some reads off the T/A Maukka calibrated light tube, the Sofirn Q8 with the K2 5400k 3v 50.2 with 18awg leads, Infineon FET, Blue Big Silver springs and 18awg bypass’s on them springs using VTC5A’s VTC5D’s and brand new Molicell P26A’s and new Samsung 20S cells…all off the MC3000 charger at 4.21v at turn on…

At 30 seconds it is extremely hot, too freaking hot to hold by the head! Tried getting some beam shots last night but is was Snowing! Maybe tonight….

If a couple of hundred to a thousand is “about the same”, then yes. That’s what he’s saying.

Looks like minor differences, similar to results what I see - 25S's getting the slight edge. What do those lux #'s means in terms of lumens? Dunno what your scale factor is.

Interested in the dice&slice #'s before/after - if/when you get them. Another great job here KB!!

My modded FF/SolarStorm SP03 has 3 SST-40's w/dome and gets about 265 kcd (~7000 lumens) now. Replacing with 3V XHP50.2's I expect slight loss in throw, maybe 5-10%, so thinking of dice&slice - if I get 40% boost in kcd, then could hit about 350 kcd, and roughly 10K-11K lumens.

It's really a decent mini Shocker - 3 nice size reflector cups, 85 mm head diameter, 4 parallel cells like an SRK/Q8.
