XHP-50 P60 Drop in AliExpress

Thank you for the link Marc E.

I’ve ordered one too. It’s the first XHP50.2 drop in I’ve seen on sale. Should be a slight improvement on my T6 drop in (2.5amp draw).

I have already modified a couple of flashlights by replacing the XML2 with a 3-volt XHP50.2, without making any other changes; the drivers provided 2700mAh; the lumens in addition to an XML, there are, and the beam of light is more flood (at least with the parabolas of default with a diameter of about 27mm); I think the performance of an XHP50.2 is higher, with the same Amp, at 3 volts.
Overall I am satisfied, in fact, slowly, I will bring other flashlights to the standard one.
Regarding the P60, yes, the problem is the greater heat, it is a must to fill the space between the P60 and the head with metal plates (I use aluminum, beer cans) but certainly copper would be better

Got mine in yesterday….12 transit days.

Put it in a Solarforce shorty with purple Efest.

Yard pics are low and high.

White wall pics are at 2 and 3 feet….

I like this drop in…

Great, that is a bit brighter than I thought it would be. A few extra 7135’s should help even more. Thanks for the pictures. Mine is still in the mail.

Is it possible to build a P60 drop-in that can handle 4 x 18650s? I have a Solarforce Gladiator host that needs a drop-in. What components do I need to build one? I would like a longer run time just in case when power is out in my country.

Hey Chris nice to hear from you again and doing videos on YouTube

Sadly many just waste the extra voltage. You’re better of with a single cell P60 and three spare batteries for longer run time. At one of the cabins we camp at, its power is limited to a single solar panel. This keeps an AGM trolling battery charged. It lights the cabin on 12 volt system plus a little 200 watt inverted. That battery alone can charge items for a long time and be recharged on a car. Might be an idea for long power outages.

I don’t have a car and a solar panel. I don’t want to carry a battery case with 3 spare batteries inside it. If you have a look on goggle a Solarforce gladiator is a 4 x 18650 length P60 drop-in host. Nobody wants to change batteries every now and then in the dark. Many thanks for you opinion.

I have a SolarForce Gladiator with one of their 1-4 cell dropins. No extra runtime with extra batteries over using 1 cell. They just wasted the extra voltage in the driver. I know of no 17mm driver that lowers voltage and increases run time by raising current potential. One possible option is to use a Cree XHP35 LED that is build for 12 volts and much lower current for equal output.

How about a 4 LED P60 drop-in that can use 4 x 18650? Can you please give me a list of what I need to do my own? I just want to give it a try. Thank you so much for your reply and I’m very sorry if I sound rude.

I got two of them a few weeks ago. One I left with the 8 7135 chips at 2.8 amps it’s an okay light with lots of spill. The other I added 4 7138 chips bring it up to 4.3 amps and it really brings this dropin to life. As is maybe 1100-1200 lumens, extra chips 1500-1600 lumens. My 12 7138 chips dropin from Pflepro actually measured 1790 lumens at 4.56 amps. The dropin is definitely worth it and works very well. With the extra chips it needs a good wrap of copper and is very much worth the effort.

Do you sell a P60 drop in than can use 4 x 18650 by chance?

Sorry no. Take a look at these.

Your output is going to be around 1 amp. You might not get any extra run time with more than one cell. The LED change out in the Dropin is going to only need a soldering iron, nothing fancy. You’ll need a 20mm star with LED.

Hi, I’m new to flashlights… already starting to get addicted.
I’m assuming this XHP50.2 light is designed to be used with a single 18650 battery, since the listed voltage input is 3.7V~4.2V.
But are there other battery options for this LED in a P60 flashlight? For example, what happens if I power the flashlight with two CR123a batteries instead?

@T80Eagle:

There's a link in my signature on how to post pics on BLF.

I bought two of them when they came out. Two CR123A’s could fry the driver. Max continuous draw rating is 1.5 amps on most CR123A’s this dropin draws 2.8 amps on high. Two good reasons not too. However this dropin was good at 2.8 amps, I added 4 chips to one and at 4.2 amps it’s even better.

Ok, if I understand you, it sounds like two CR123a batteries would produce too much voltage and not enough current, which makes sense to me.

You added four 7135 chips, which put more current through the emitter, and I’m guessing, that required a better heat transfer method? Man I have lots to learn. I have a soldering iron but I’ve only used it for fixing wires, I’m going to look for a guide or youtube video before I short something out lol

I wrapped the brass part of the dropin with a strip from a 24 ounce Monster. Copper wrap works the best but with the large soda can it thicker and only takes 1-2 wraps to fit it tight into the host. The aluminum strip needs a light scrubbing to get the coating off for better thermal and electrical contact. Normally “as is” with a 2.8 amp dropin works fine without a wrap. Those 7135/7138 chips come in 350 and 380 milliamp flavors. AMC7135
