Buy a smooth & try it on that one. If it doesn’t work out you still have the stock reflector.

Hmmm, not a bad idea. :+1:

Thanks, I have one occasionally. Even a ’blind hog’ finds an acorn now & then.

Keep us posted if you do it please. :+1:

Or slice and dice the 50.2 to optimize it for a smooth reflector…

Already did and didn’t like it.

@JasonWW

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.

Short Review of Sofirn SP33 v2 with XHP50.2

Curiosity got the better of me, so I sliced and diced the stock emitter. Measurements before: 20.5Kcd, 286 meters (a bit higher than my previous measurement of 18.5Kcd) and 2,200 lumen at about 20 seconds. Measurements after: 27.5Kcd, 331 meters and 2,030 lumen at about 20 seconds. The tint definitely shifted. Stock the SP33 v2 was definitely cooler in temp compared to the C8F 21700. Now they have flip flopped. The C8F is definitely cooler in temp. The SP33 hot spot used to be slightly bigg…

You sliced it, but you didn’t dice it. Important step. By removing the extra phosphor that sits on the substrate and surrounds the die you lose all that yellow peripheral light.

Zozz did a neat photo documentary on doing this with an 70.2 emitter

Here is the PHOTO DOCUMENTARY ZozzV6 did about XHP70.2 dedoming. “Slicing & Dicing”.

Uh, yeah, kinda forgot to mention that clicking on that photo takes you to Zozz’s thread… my bad…

[teacher]

That’s cool… I did not realize that when I posted the link.

[DB_Custom (Dale)]

I meant to come back in and declare it, got sidetracked. (happens so easily to a feeble mind…)

[teacher]

I understand & can relate.

I don’t really see how mine is different from this link. Did I not cut close enough to the edge of the die?

Here’s Zozz’s pic.

Here’s mine.

Maybe I’m not doing an important step? I’m not sure.

[teacher]

Hmmm…. The only differences I see are.

• His slice looks a bit smoother than yours
• His slice ’appears’ to be a tiny bit deeper than yours
• A couple of your sides could possibly be ‘diced’ a tiny bit more

But, these observations are just made from zoomed in pictures…… so who knows.

Second photo is out of focus so who knows.

Huh? Focus looks the same on both.

+1 Looks in focus to me.

@Sofirn

Good news

Is there news when a choice of different CCT (3000К, 4000К, …К) will be available? Competitors are coming.

Some supplemental impressions I would like to share about the new SP33 V2.0 (XHP50.2)

I've tested some batteries. All unprotected 26650s would fit, i.e. the supplied Sofirn 26650 5.500mAh, the Dolidada 5.500mAh (fake PLB-55A cell), the Shockli 5.500mAh and the Keeppower 6.000mAh, both PLB-55A cells. However, I failed to put in a protected Keeppower 6.000mAh as PCB and shrink make it too thick to fit into the battery tube.

The Sofirn lineup for size comparison...

Some tactical lights for size comparison...

Some non-tactical lights for size comparison...

I tried to create some kind of schematic to visualize the user interface. I hope it's useful. I'll be glad for any feedback if you see room for improvements

I also tried to illustrate how the boost driver works i.a.w. the modes and their stepdown behaviour. The dotted lined boxes mean you have to use a doubleclick to get into this mode. The side switch indicator will also work differently depending on the actual voltage of the battery. The 2min-stepdown will only be triggered on Turbo, i.e. 2.500 lumens. Depending on actual ambient temperatures the "high" mode can run stable. My SP33 has automatically shut off once voltage was depleted down to 2.7V, so LVP works.

Last but not least some outside beamshots on Turbo mode (2.500 lumens)

Bottom line: The SP33 V2.0 is a very nice allround flashlight with good thermal management, a hefty body, a simple but useful UI and a very good price/performance ratio.

Cheers,

Thomas

BTW, SP33 also works with 3xAAAs. I tested it with cheap supermarket NiMHs and it works on 400lm about 45 mins perfectly flat regulated. On 1000lm it runs only about half of the second.

Will this ever be offered at Amazon without the battery and charger?
