C8 "screw in" pill with XM-L and 105c driver from Intl-outdoor

LED Flashlights – General Info 18650 Flashlights
1

Recently, I bought one of the $9 Ultrafire C8 flashlights on Ebay. It came with XR-E and a cheap plastic lens and reflector.

It seemed substandard when compared with my KD C8 and my XinTD from IntlOutdoors.

Then I saw that International Outdoor sells a "screw in" C8 module with good features.

I replaced the reflector for about $2.80 and the lens with a coated one, about $4.

Then I got this C8 screw in module, XM-L with a 105C driver. Pick whatever modes you want, same as any 105c driver.

The original Ultrafire C8 body was OK.

Pics of the C8 pill with XM-L Led and 105c driver is here:

Bottom line, I ended up paying a bit over $30 for a C8 flashlight with top features.

I did not need to replace the switch, it is fine with the higher current.

I have C8 warm white from Manafont and change a driver with 105c too

But I can't use a 18650 with PCB anymore, may be next time I will mod C8 's tailcap.

Where did you get a reflector $2.80?

Also bought that cheap C8 with plastic reflector and lens, where did you buy the reflector for $2.80 and the lens with a coated one for $4.

Thanks

Ian, I can't remember where I got the lens, it was one I already had.

Here is a link to a tempered glass lens @ $2.80:

It says 2 pack in the URL but it is for just one lens.

Also, I think that flashlightlens.com has an ultraclear acrylic one that will work with a little edge sanding:

In the OP, I forgot to mention that the led is not glued down to the pill. That is good because you can make sure that it is centered when you install it.

The led is soldered to the wires but is not glued to the pill. In the package you get thermal glue and 2 white plastic rings.

I used a toothpick to put a small amount of the glue under the led and then installed the white plastic ring.

Then I used the reflector to center the led and then screwed it together and left it until the thermal glue dried. It ended up centered and with just a thin layer of thermal glue.

I would do that kind of modding also, 16$ is a decent price to get the modes right and PWM higher ;)

Thank Stevetexas

I will be building one that myself.

Already have the C8 pill on the way.

International outdoor now have the 42mm AR coated glass lens.

ordered 2 for my C8 and similar lights

Ian,

That is great, I just ordered some spares for myself. Great price for coated lenses.

13

I tried to order but can't find the add to cart button for the C8 module page. I wonder if they are sold out. I sent a quick message to Hank/Joyce and will find out soon.

14

Hank fixed it. It works now

Gack, this stuff changes faster than I can keep up. Yesterday I'd never heard of a "C8 pill" and today they've been around forever.

So obvioiusly I need some.

This looks like it's a Romisen C-8, but no brand name.

It's direct drive. I do like the zoom-to-flood lights a whole lot.

I'm wondering if the "C8" in the Romisen light is coincidence or if it can take these screw-in C8 pills. I have a Romisen C-8 that I bought second hand, someone had modded direct drive, that needs a new LED.

And is there a warm or neutral C-8 screwin pill somewhere available?

16

This is the first Screw In C8 pill that I know of.

I am red/green color blind.... the color looks OK to me.

C8 shaped flashlights are made by a lot of brand names today.

I just ordered one of these C8 dropin pills for what is now an Ultrafire host.(It was a cheap Ebay purchase to which I added an 18650 extension tube + battery) Anyway I destroyed the original cheap aluminum pill, and before I do that to a good one, does anyone know what the max input voltage is?

18

the C8 pill from I.O. (link in original post) use an 8xAMC7135 board, so maximum voltage input is roughly 6V. So 2xCR123a primaries are probably OK, and 1x18650 is ideal.

19

Thanks for your speedy response Slim Pickens. I will stick to a single 18650 for this. You haved saved me from another mistake.

Perhaps for my next experiment I will try to rebuild the destroyed aluminum dropin with one capable of handling

2 X 18650 using the extension tube. Any suggestions will be appreciated.

Thanks again.

No problem.

InternationalOutdoors started selling these drivers pretty recently-they're a little pricier than AMC-based regulators, but they'll handle the higher voltage. EDIT: that one may be too big (18mm+) to fit the C8 pill.

Here's an alternative. JayRob over on CPF and LPF uses them in his custom XM-L Maglites. KaiDomain can be kind of sketchy but that driver is solid.
