14500 OR AA zoomie on sale for 19.95 (discount after you add to cart). No idea if it’s any good.

Interesting light on aliexpress…

Expensive, but I thought it looked kinda slick. Same length as TC20 with a thinner head diameter.

Nitecore has similar stuff based around their proprietary 21700, with magnetic attachments:

I like it when they give you a choice of XHP70 and CREE XHP70, hhmmm.

What about these:

What is a P90? And what is a XHP90?

The first one above can do 3500 meters, not bad for a $43, 32 mm head diameter light!

The xhp90 is not from cree, it’s a smaller unknown company that makes a 4 die led on a 9mm x 9mm base. I hear they can’t take much amperage. Maybe 5 to 8 amp.

Nice find!

That 1st one is similar to the one I posted, interesting too with the added display screen feature.
It appears to have the exact same UI with hidden Turbo/Strobe/SOS.

It’s also listed on aliexperess…

And now we also have the P80 !

P70, P80, P90…

Anxiously awaiting the release of the P100! :person_facepalming:

Having a P100 bead with 10 gears in a copper (yellow gold?) host is my dream!

Ultra Bright-High Lumen Flashlight
The rechargeable flashlight uses the OSRAM P9 LED, 3300 lumens, which is much brighter than the other general one.

It's a cheap Amutorch X9, but cheap not just by the price. If you look close at the main pic, it actually has rubbed off anodizing. Weird they'd use a marked up piece for their pics, or maybe the anodizing is so weak, they couldn't find a good sample. It's a little bigger than an X9 and uses optics, not a reflector.

The video for this light shows a SHREPA brand light, anyone know of that brand?

Thanks, I thought it looked familiar but couldn’t place it. Besides the optic vs reflector difference it also has Osram P9’s instead of SST40/XPLHI, I’ve been seeing this P9 in more lights recently, I know nothing about it, I have to read up on it.

Was going back through this thread to catch up and found ^ this post ^

I have this light too, but mine is the Ultrafire UF-Y1 from fasttech…

Got it because of the unique “fine machining” style knurling, was hoping it would be as nice as it looked in the photos and it actually is pretty much, so for that reason I really liked this for a host until I took it apart (it has the same faults as the aliexpress version)

I too planned to swap out the angry blue emitter and wrap the “mini drop-in” to fit better in the head, but it really needs a power boost and elimination of strobe mode.

And I also have that Ultrafire U-F10 mini Zoomie with the (same?) e-switch tail driver, in the thread for that light I remember someone giving it a boost by stacking a resistor on the driver, also vaguely recall some trick to eliminate the strobe mode or make it one mode, I’ll have to read up on that again.

What effect does swapping the resistor on the ledboard from 50 to 220?

Without knowing the details of how the driver works, there seems to be a few generalities to drivers. Like in the picture above, see the big R100 resistor? The large size gives it a higher power/wattage rating so it can handle more heat. The R100 label means it’s 0.100 ohm which means it’s a sense resistor. Manufacturers use these types of resistors to fine tune the max output. The general trick is to reduce the resistance to get more power, but you have to accept you might burn up the driver. You want to go down just a little bit, maybe replace it with a R090 or stack a R600 on top to create 0.090 ohms. Stacking resistors involves tricky math so I usually use a calculator like this. See what the effect is. Brightness may go a little or none at all. If you have a backup driver you keep going lower to find the limits. Maybe 0.75 will make a noticeable increase it output or the driver might burn up. You typically want to take very small steps or find other people who have already experimented on that light and use their recommendations.

Ps, looking at the driver above, unless there are more components on the other side, appears to be a single FET driver and the sense resistor is just to limit output.

To me that resistor just seems to be like current limiting resistor in series of that sot23 device which maybe is transistor.

Yes.

I have this one. It can be modded with a different driver, but I’m not sure if you’d find it any good.
I put a S2 pill onto it (with the threads “shaved”), and used a S2+ reflector. It has a platform in which the switch (reverse) sits, making contact with the driver.
The battery tube has a large spring sitting in the back, but sometimes even the longer 18650s don’t touch the “+ button”.

It is not a hard mod, but it can be tricky. The light is heavy, all SS.
