It’s for sale under the names YZ-BG7236 and Ultrafire DV-S5 but I haven’t been able to find any reviews or impressions of it under those brands and I haven’t had much luck trying to find it under other names.
Does anyone recognise it and could point me in the right direction? Even potentially related lights would be something to go on.
Details of the construction/features
Thanks.
OK . At this time there are 84 reads on this thread .
I think the reason why no one has responded yet is probably because no one has this light , or for that matter , any lights like it .
Here are some reasons why . ( Remember that you also asked for impressions , so here is mine .) 
This light is ugly . The color is kind of a retro turquoise , which while eyecatching and certainly unique , doesn’t do anything for me .
The body style …. It appears the the tailcap is larger in diameter than the body and head of the flashlight , it doesn’t look balanced .
I do note the presence of double O-rings and fairly thick body wall , which is good .
The switch … sticks out way too far . While it would be easy to find in the dark , it seems like the light would be easily accidentally activated in a pocket .
Again , just my personal impressions .
IMO, the switch sticks out way to far. I see it being snagged and inadvertently being activated. I like side switch lights, but not that one. I’m guessing there are more folks that don’t like it than folks who do like it.
looks like a cheap chinese conversion of a vape device

It looks like a remote detonator for a bomb.
I kinda like it. If it were cheaper I’d pick one up. I’d go with the 1700 lumen model, though :laughing:
That button sticking out looks like it would be a PITA, snagging and gathering dirt. I’ve never seen another flashlight with a side button like that.
It only has three modes, low, high and strobe.
If I was going to spend $20 on a flashlight there at least a dozen which would have more appeal than that. Maybe that’s a common reaction and why there are no reviews?
There may be no reviews of this light at all. Here is why.
It is what I call a special interest light. It is not black or grey, it is not ‘tactical’ or a record thrower so the usual suspects and brand collectors do not review it. There are hundreds of flashlights like this at DX or FT.
Also there are some indications that it may not be a hiden gem:
- The description of the YZ-BG7236 does not even claim that it has a genuine Cree LED. If you are lucky the LED is “not too bad”.
The light is not cheap enough for that.
- The claimed output current of 1000 mA could be correct for a simple HI-LO-STROBE driver. Light output will be around or less than 400 lumens maximum.
Nobody wants to spend time on reviewing a VW Beetle that claims to have 500 HP with a stock motor.
(BTW the UltraFire DV-S5 would need more than 3 A for its claimed 1200 lumens with an XM-L2. On a stock light?)
- The light looks very similar to the UltraFire DV-S5 and seems to use similar components. But it is not rated as a diving flashlight.
What does that mean for waterproofness? (Anyway, these are not divelights. They are waterproof toys at best.)
- The button design looks not great to me. The button sticks out a lot so it will get accidentally activated in you pocket. Any stuff in you pocket will get caught in the undercut of the button, making the light impossible to operate.
The internal design of that button may be very sophisticated so it keeps it from getting ripped off and even makes it waterproof. But from my experience with such lights I would not bet on that.
The button makes the light impractical.
- UltraFire is not a manufacturer but a sales agency that constantly generates new lights. Depending on the actual manufacturer the lights are of mixed quality. Even if you buy a well known UltraFire model a few years later its quality may be terrible. That is why good reviews are almost useless for those brands. The SkyRay King problem.
YZ is not even a known brand.
.
All this combined means that the YZ-BG7236 most likely is not such a great light that a lot of people will want to review it.
.
It may be a good light for you though. If you like the colour and the design of the light - go buy it.
There is no other way to find out than playing the China Lottery. Maybe it is exactly what you want.
It doesn’t sound like anyone recognises the model or factory, but I appreciate everyone who has taken a look.
I’m not sure that argument holds much water, most other over-marketed lights I’ve come across have had a review. There are plenty of ultrafire, skyray, trustfire and so on lights reviewed. I get the impression that most people here have bought a light with what they know are bogus output figures.
(BTW The Ultrafire site says 3.8A for it:
Flashlight, Batteries, Tactical Gears - UltraFire Official Store).
If it’s 350 lumens with only basic waterproofing then that’s perfectly fine with me.
Judging by the comments I believe I have reasonable expectations for it, I just want to avoid something that is so badly made it stops working after a few months.
What are fasttech like with their stock choices? Do they usually do a good job of avoiding the really bad models?
I have not seen 3.8 Amps in a stock light of that class. On land it will quickly fry the driver. (People whine about 2.8 A in an S2+ …)
Not really. It is one of the better shops but they sell what people buy.
