Short Review of Sofirn SP33 v2 with XHP50.2

Just an update, I swapped a new domed 50.2 back in my light after one day of the sliced dome. I didn’t like it. My entire spill light was yellow. It made things look wierd. The stock domed emitter is not the prettiest (meaning all 50.2 and 70.2 leds), but it seems a better compromise.

I’m thinking Sofirn should do a real OP reflector instead of this very light, almost SMO reflector that is stock. Then it would mix the yellow corona with the white hotspot and get a nicer looking beam. You loose throw, but it should look nicer. I consider this a short range, walking around type of light anyway.

I DC Fixed my dedomed SP33 but still not liking the color. Nicer beam pattern though.

I have a stock SP33 that I accidentally dropped and the glass cracked… anyone know where I can get a good, inexpensive replacement lens?

The first thing I would do is contact Sofirn to see if they can sell you a replacement.

Also, you can measure the diameter and check stores that carry flashlight parts like Kaidomain.

Parts from China should be cheap. There is a USA store FlashlightLens.com - Your source for high quality glass and acrylic flashlight lenses. - Flashlightlens.com - Online Store
That can certainly have it, but it’s probably more expensive.

My 5000 K XHP 50.2 came in today .Totally messed up the swap. I should of taken the new emitter off the new 20mm board and put it on the 26mm board that comes stock in the SP33. Instead I installed the 20mm board thinking there was clearance between the soldier joints and the reflector. Well there is if you keep the soldier blob real low but mine shorted . That in itself would not have put the kabash on things but when I removed the lens , the gasket stuck in it and pulled off the dome. Talk about a purple beam. Long story short, put the original emitter back in and I am back to where I started. Oh well. Modding 101.

I dont like that after the turbo is gone due to low voltage you have to double click for high

Thank you DBC and Teacher for using my XHP70.2 dedome thread as a reference! :blush:
I ordered an SP33 and soon I will try XHP50.2 too.

Ok definitely time for me to upgrade from my panny bs!

Quick question Jason tho… how are the “5500mAh” Sofirn cells that are included in the kit on amazon?

I have a bunch that I just use as backups. Just ordered some of the black Shocklis from Richard and plan on buying more unless there are even better cells I should be considering??

From post 177.

I was told by Sofirn that their 5000 and 5500 are basically the same cell, but some gave higher capacity and are labeled 5500mah, while the lower ones are labeled 5000mah.

The Shockli 5500 is a superior battery. A real 5750 or so mah and good at delivering high amps. I think it came out in either 2017 or 2018 so it’s quite a modern cell. I use it in my SP33 and get longer battery life than any of my other 4300-5000mah cells.

Thanks guys. that’s interesting to me at least :slight_smile:

Does the xhp50.2 version come in neutral white or is it a typo? I think they copied and pasted from the xpl version but not sure. https://www.aliexpress.com/item/Sofirn-SP33-Mini-Powerful-Led-flashlight-18650-torch-light-CREE-XPL2-LED-Mini-Handy-flashlight-6/32831075588.html

It says 5350K-5700K, but it’s more cold white. More towards 5700K or maybe even 6000K. I would not call it neutral white.

I just received mine from Sofirn official shop and it's indeed cool white but that's no surprise as Sofirn advertise it as 6000-6500K.

I would be carefull about what is said in your link as the only color temp "5350k-5700k" mention is in the "clicky order thingy" and the pictures that show the led aren't from an xhp50.2 (obviously smaller led)

I don't like cool light neither and my idea was to order the one from Sofirn shop and change the led for a warmer one if i really dislike it.

Got it only two hours ago so i have no tested it for real yet but my first thought when powering it for the first time was "uuuuh what a ugly green ring" wich seems to be typical for xhp50.2 with reflector

Interesting, 5700K is considered Daylight White. My flash units fire at that temperature for my camera’s. These are $400-600 flash units. I’ve always found it interesting what Kelvin people find “comfortable” when in real life the actual Kelvin of ambient light is not what most people think it is.

Are you confusing green with yellow? The 50.2 and 70.2 typically have a yellow corona. I’ve never seen green.

To me, the flip chip technology from Cree (XP-G3, XP-L2, XHP-50.2, XHP-70.2, XHP-35.2) has a greenish yellow sickly aura around the hot spot. I’ve found that slicing the phosphor off the substrate surrounding the die pretty much eliminates this, the only way to do it though is also with a slice of the dome. There are no bond wires but it’s fairly easy to mess up and get a bit of phosphor off the die itself and reveal the blue light.

@ Kame Sennin;

Changed the 5700º to 5000º and see no yellowish / green halo. But the tint is somewhat ‘softer’.

Arrow Electronics

Well yeah, Sidney, that one’s a 90 CRI version. :wink: Nice find! It won’t put out anywhere near what the cooler white ones will do but still, beautiful light…

@ DB;

I did a ceiling bounce measurement w/ phone app and got 2579 lm (instant on). My measurements may be off some as my reference light is a Dorcy 3s “C” cell (alkaline). And I do downplay the data (throwing out the highs and lows on some 5 tests).

I believe their boost driver has something to do with this value - I was also very surprised. And the price / shipping was excellent!

What i meant is are there two versions. The one in the sofirn official store on AliExpress says 6000-6500k but there’s another seller on AliExpress which shows a warmer tint. I think it’s just a mistake tho. Btw do you think this is better than the convoy S11. I need something which is floody but can do 1000ish lumens continuous whilst still being comfortable to hold.
