Short Review of Sofirn SP33 v2 with XHP50.2

This is the new “version 2” of the Sofirn SP33 which now has an XHP50.2 and a boost driver.

The UI is really great on this one.

One click on/off.

When you hold down the button the 3 main modes cycle low, med, high, low….

When on or off, you can double click for Turbo. There is a tiny ramp up to turbo. One more click and you get a smooth ramp back down to your previous level. The ramp up and down seem nice in comparison to the C8F’s ramp up to turbo and sudden drop back down.

Eco/moonlight is hidden. From off you press and hold the button.

Strobe is also hidden. Thumbs Up You have to first double click to Turbo, then double click again.

The electronic lockout is done with our fast clicks. You will see 2 confirmation blinks. Any time the button is pressed you will get 2 blinks to tell you the light is locked out. To unlock, you do four fast clicks again. You can manually lock out the light with a small turn of the tail cap.

The spacing in the levels is really good. The emitter color is nice. I’m digging it. 

Full details can be found in the updated manual courtesy of Lux Perpetua.

Sofirn SP33 v2 updated manual

At 3.70 volts the 2200 lm Turbo mode dissappears. Now when you hold down the button you cycle between Low and Medium. A double click takes you to the new “Turbo” level (high mode, 920 lm). So you have Eco, Low, Med and a 920 lumen Turbo mode.

At 3.40 volts you loose High mode. Medium becomes the new “Turbo” mode.

Whenever you turn on the light there is a battery indicator feature in the switch which will light up green for about 5 Seconds when the battery is above 3.4 volts volts. Below 3.4 volts it will light up red and Med is only accessible with a double click.

The mcpcb is 26mm and 6v.

No retaining ring. If you look closely around the edge of the driver you will see a light blue color which to me looks like it might be adhesive.

Here’s a ceiling shot. You can see that the tint is slightly cooler than the C8F. The hot spot is also a tiny bit larger. I like it.

Candela is 18.6 kcd or 272 meters of throw.

Parasitic drain is 121 microamps/0.12 milliamps. Very nice!

The mcpcb is 26mm and 6v.

Lumens are measured in a TA Lumen Tube and it’s calibrated with one of Maukka’s calibration lights.

Amps are measured using a large wire across the tail and a UNI-T UT210E clamp meter.

This is with a fully charged black Liitokala 5000mah.

Eco 0.036A for 5 lm
Low 0.23A for 140 lm
Med 0.60A for 375 lm
High 1.59A for 920 lm
Turbo 5.80A @ 20s for 2,200 lm

Samsung 30T 21700 on turbo:
5.27A @ 20s for 2,200 lm.

Keeppower 5200mah on turbo:
5.80A @ 20s for 2,200 lm.

As can be expected with a boost driver, the output levels are very steady. Turbo is usually 2,240 at turn on and slowly drops to 2,200 at about 20 seconds.

Shockli 5500mah and KeepPower 6000mah do fit.

I’ll add driver pics once I get it removed.

The only improvements I can think of is bypassing both springs. This can help keep the voltage higher and give more cumulative turbo run time.

Also maybe have a locator switch light on all the time. I’ll see about adding that feature if I can get the driver out. It appears to be glued in place.

To sum it up, this is a great light and for only $23, it is an amazing bargain as well! I give this light a big thumbs up! Thumbs Up

Edit: New driver pics!

I used a small Allen key through one of the anti rotation screw holes and tapped the driver loose. You can see that part of the pcb got pulled apart due to the glue. Luckily the little components look okay.

Glue everywhere.

A shot of the switch leds just below the switch.

The machining in the head looks the same as version 1.

Ordered one on 11/11.
Are the reflector and LED accessible?
Or is that glued too?

Thanks Jason. Lobe your tear down threads. I ordered one on 11/11. Should be getting it soon.

So, no retaining ring on driver ? Hmmmm.. Seems to differ from DB CUSTOM’s review of the earlier XPL version. Interesting.

Yes, the bezel is just a little on the tight side. The mcpcb looks to be about 24mm and made of copper.

Yeah. I tried pulling on the spring, but it won’t budge.

It may need to be pushed out from the emitter wire holes on top.

This is a nice thread. I have not seen it before. There is a picture of the driver bottom with no retaining ring for those interested.

My pics won’t be up until late tonight.

I might want to try a Nichia 144 and a TIR in there.

So Jason, how is the tint?
Ugly cool or acceptable white?

I can see in my pictures that there is an adhesive of some type around the driver.

It’s cooler than the C8F. I have both beams side by side. I like it and don’t plan to change it.

Okay, pics are added and I think post 1 is pretty complete. I still need to get the driver out, though.

Thanks Jason for the update. Sounds like a very nice light overall. Do you think high mode would overheat it if used for a long time? Does it step down from high?

I don’t know. I usually use it on Med for walking around and it doesn’t even get warm.

I’ll try High mode tonight and see what happens.

What are the screws under the MCPCB holding?

Do they hold the T-shaped driver/switch board in place?

Great review JasonWW! Smile

Lately, I took some beamshots outside at 3°C / 37°F and the SP33 didn't get substantially warmer than my hand, even after quite some runtime on turbo.

http://budgetlightforum.com/comment/1416322#comment-1416322

The tint shift is hardly noticeable when outside. You might recognize some yellowish tint on the edge of the spot, somehow identical to the SP32A V2 that uses the XP-L2. FWIW, the SP32A V2.0 heats up significantly on turbo while the SP33, being far more hefty, remains comfortable as a summer breeze.

 

For comparison:

Sofirn SP32A V2.0 (XP-L2)

Sofirn SP33 (XHP50.2)

They could be holding nothing and just prevent the MCPCB from rotating (and shearing the ledwires) when closing the bezel.

I noted those screws in another thread and wondered if they were doing retention duty for driver components.

Since then, I’ve removed and inspected them.

They are quite short, not long enough to retain anything on the other side of the MCPCB shelf, so they must be there to keep the MCPCB from rotating… or as conversation starters.

This is also what I think. They are just for anti rotation.

You can see in Dale’s thread where they don’t do anything as far as the driver is concerned.

I ran High mode continously for about 20 minutes walking around. It’s a slightly chilly 60°F and windy night. Heat was not even a concern and it didn’t step down. It was just barely warm. Should be fine.

If left in a hot room with no airflow it would surely get warmer, but even then I doubt it would get so hot that it would need to step down.

By this, do you mean buying it on Amazon US? I have not heard anything about it. Sorry.

Thanks for the review Jason, looks like a decent all around light. Will it fit the longer protected keeppower 26650 5200 as that's the only 26650's I have at the moment.

I think the sp33 ver.2 is referring to the current retail version with the xhp50.2.

There was an earlier version of the sp33 using the xp-l led.

I don’t have any protected 26650 anymore to try, but 21700 fits. The springs have a lot of height to them and can compress a lot.

So even though the protected KP 5200 is a poor choice for this light in my opinion, I think it would fit.

Obviously, you can also use an 18650 as well.

Did someone ask about this? I thought it was well known.

Why would it be a poor choice since turbo only uses 5.8A and the protected KP can sustain 12A?

 

I asked about  ver.2 as I didn't follow anything about the SP33 at all until today!

That is such an old cell with poor chemistry and high internal resistance. You get a lot of voltage sag with it and boost drivers need as much voltage as possible.

The protection circuitry also adds resistance and reduces voltage.

What I’m refering to is mainly in reference to turbo run times. If you are only concerned about steady output on the lower levels, then it’s an okay battery for that.

I must have missed your question.

Here is DB Custom’s thread on the first version that uses the xp-l.

The thread transitions to the newer version.

I need to get with the times as I thought it had modern chemistry.  I've replaced most of my 18650's with 30Q's but haven't replaced any 26650's as of  yet.

I think the KP 5200 mah came out in 2014. They have since been replaced by the 6000 mah version which is superior. The blue Liitokala came out, I think, in 2016 and is also superior. There have been a lot of better cells that have came out since the KP 5200 mah.

Do you think the chemistry is any safer with the 6000 mAh?
