Would it be safer to use a protected battery in the SD05 just in case water does creep in and creates a short?   I’ve always been using protected in my Sofirn SD02 diving light just in case.

You’ll be limited to finding a charger that takes protected 21700’s though

True.  I don't have a charger that would fit them either.  Would be interesting if someone did a test to see what would happen if the flashlight leaks underwater with protected and unprotected

batteries

I'd prefer those Ukranian battery guys that enjoy stuff like that!

how far deep can this light tolerate under water ?

I don’t think anyone has confirmed the 100m specification but this is the deepest I’ve seen the light in use: Video Review

I have just ordered the light Smile
Will try it down to 60-70m just like I did here:

Too bad the turbo mode is going to high after 3 minutes…

60-70m than you are talking some serious tech diving, not really related to this forum but really curious about your setup, being a novice diver myself (just got my nitrox certification)

I have the older version (xhp50 with step down). I ordered it about a year ago, and have gone diving with it 4 times. It worked great every time. I have not used it out of water much as I fear it might overheat over time.

I am new to diving, though, and want to ask those who are experienced divers if this light could be used as both a primary and secondary light for night diving when I get to doing that. If not, what budget light (under $100) would you recommend for the primary light and/or what characteristics should I be looking for in the light?

Sofirn is using the 3V xhp50.2 again now in 6500k.

Anyone compared with SST70 and is the SST70 green at lower level? I have seen YouTube review that says the sst70 is brighter and throwier.

Also, any graph of lumen vs time for the newer xhp50.2 3V?

Can I use flat top or button top 21700 batteries?

The flat top; the button top if it is longer can give problems for the closure of the cap

Flat top Molicel P42A’s ran perfect last month in Belize. Didn’t have a camera though, so so pics. Sofirn had a 5k version for a while (earlier last year) which I think I’d prefer. Still the 6.2k or so (estimated against other lights) version really looks great. Even on some daytime dives we used it in some caves and the colors “popped” nicely with a light at 70-90 ft. down (where everything looses color that deep). We also had the old SD-02 which was great too!

The lanyards are the weak point: have to get pro-level lanyards if you don’t want to loose the light (*AND have to stow it on the safety stop so you don’t tangle yourself coming out in rough water (*which Belize IS compared to other places we’ve dove). But it’s worth it for sure to ride the nurse sharks at Esmeralda, and spear hunt barracuda and lion fish- which are BOTH super tasty!
