My surefire turbo mini arrived. It is advertised as 95k LUX with an 18350, and 55,000 with cr123.

My first move was to test this. I measured 100k LUX at 1m with 18350 fully charged, and exactly 55,000 with a new cr123. My modlite plhv2 dual fuel measured 80,000 lux with a new molicel p28a, for comparison.

More to follow.

Can we request for some comparative and walk-around photos of the Turbo head, including that with regular E2d/E2e's heads (KE/KX/hex)?

I generated some interesting data. I tested the Surefire Mini DFT Turbo using my lux meter, and found that it was 100K lux or above at turn-on, and laser measured temp was 78*f. At 1 minute, the temperature measured 100*F and the LUX was unchanged. At 2 minutes, the head measured 100*F, and the LUX had been cut in half to roughly 50K LUX. At 3 minutes, the head was 100*F, and LUX was still hovering low 50K range. At 4 minutes, the head was 100*F, and LUX was still hovering low 50's, at 5 minutes, the head was 99.5*F, and LUX was still low 50's.

I then placed the whole light over my heating vent, and laser measured a temperature of 108-120*f depending on what part was lasered. The light performed at 100K+ LUX.

It seems SF is very strict on their thermal limits, but it's also quite intelligently done.

Can you take a photo of the LED? And then I remember that I had something like a dispute with one of my friends, will there be Cree XP-P or Osram inside?

Although, it could be Luminus SFT

It looks like an Osram to me.

She is very similar. I looked elsewhere
it seems that in XP-P the surface of the chip is somehow raised above the white part, while in Osram it is flush.

The font type on your photo looks more like Osram.

Looks like you're right, it's some kind of Osram

What worries me, there is a feeling that the diode is sitting on thick solder pads. Usually there is some bare metal on the sides of the diode to allow excess solder to come out, as in the photo of the osram above on the red board. Of course, maybe they do not overload the diode and everything will be fine with long-term operation, but it still worries me. Previously, there were processors that sat on balls of solder (BGA), they sometimes had problems with contacts due to the thickness of the solder ball, the contact was broken. Well, a thick layer of solder is a degraded heat transfer. Also on the forum there were already reports of burned out LEDs in the SF and I saw similar ones burned out on sale on the local flea market, like this P3X

Even though it could all be my OCD. Practice will show when there will be a lot of them on hand and users and some time will pass

Bummer on that P3X.

I have a P2X Fury Defender and a Fury DFT that burned their LEDs like that.

Both are pending being sent back to Surefire (have a RMA) for fix and replacement.

How long has opticsplanet had these on their website?



No idea. But this is hopeful.

In firearms circles, Optics Planet is known to straight up lie about in stock. Stuff will say "in stock" then shortly after ordering, shipment ETA will be weeks. General advice is to buy somewhere else. Case in point, they recently had a sale on a 1600rd pack of crappy plinking .22LR ammo for $56. They ended up shipping people 400 rd boxes instead, and when people complained, they said it was a typograpical error and the price was for a 400 rd box. Well that would be believable if there wasn't a separate listing for the 400rd box ($35). Avoid Optics Planet if possible...

Optics Planet has taken my money on items that have showed as in stock when they were not. Then come the looooong backorder delay.

After the second time that happened, I crossed them off of my list of companies I buy from.

I purchased a Trijicon Accupower LPVO from them accidentally. It was an EBay listing. Couldn't ask for a better transaction.

Then when I tried to purchase some BUIS from their site, they took so long to ship I bought them locally and cancelled my order. Maybe EBay would come down on them if they were how they tend to be. I've heard generally bad things about them.
