Apologies for the clutter; my desk is getting crowded with stuff.

Not much in there for thermal transfer.

Grabbed a quick beamshot too. Top of the tree aimed at is a bit less than 200 yards.

Many thanks unkown! :slight_smile:

Looks like it might only be a $15 light, though the charging port intrigues me a little, albiet it is most likely just a gimmick. What is the actual diameter of the driver itself?

That pill/star mounting has me concerned though. No metal under the reflector, without substantial mods it seems like a 2A max light. Seems I’ll be cancelling that order then.

4

Innnnnnnnteresting… this thing is begging to be modded.

5

Thanks for the breakdown. I’m waiting for mine to arrive. Looks like a lot of possibilities for this light.

6

The charging port was definitely a surprise to me. The driver is 38.30mm. I’m thinking of throwing some copper in there and doing my best to get around 3 Amps. Just a functional decent little $13 light.

7

Hi Unknown, do you know how many amps its pulling stock and is there an easy way of increasing output on this driver?

8

How to get flashlight for $13?

9

I got .9 amps measured at the tailcap with stock leads. I’m not sure if there is any easy way to increase it with this driver.

It was originally mis-priced around 14.99 with coupon was 12.96 iirc. They’ve since raised it to $18.88 and changed it’s status to ‘promotion’ so I don’t believe coupons can be used on it. I don’t think I’d pay that for what I got, but I’m stingy. :slight_smile:

10

Just ordered one US$18.88 :~ ah well, still cheapish mod fodder J)
Does anyone know of a driver with digital switch of 3~5A that would fit this ??

Cheers David

Hmmm…. I think I’m gonna like this flashlight.
:8)

12

Yea, I jumped that greased pig, too … s) Well, I paid 18 something, also, felt better at 12 … s) s) :expressionless:

This might save us:

There won’t be any room for the copper! :stuck_out_tongue:

14

You son of a… I’m trying to save money, not spend it! You sunuva… :weary:

15

@ Flomotion, that driver is 5-18v, the pic of the battery holder suggests parallel, but thanks for the link as I am after one like that for another butcher job project.

@unknown00101 could you please let us know if it is series or parallel.

Cheers David

16

Got me … hmm, shoudn’t drink and write … s) s) :beer: :weary:

17

Parallel.

Also, it does not like protected cells; shorter protected will fit, but very very snugly (I can’t seem to get mine out currently). Flat top batteries probably wont work without a solder blob in the stock carrier.

A custom carrier could likely fit 3 18650s inside this light.

Edit: finally got them out, had to remove the top part via the little plastic tabs.

18

Thanks, looks like I will be converting it to series 8)
The up side is that 5A will be easy using series, the down side is the Minister of finances has just said the the treasury is closed for the rest of the year :_(
Hey, I just realised, this means I can destroy play with the original driver until it gives up, then do the series mod, twice the fun for the same price :money_mouth_face:

Cheers David

Edit, shorten the driver spring, extend the battery housing and shorten those springs and hopefully protected cells will fit.

19

Thinking towards the possibility of making a 3 x 18650 carrier, are there any requirements as far as distance between the cells? Could I make a carrier where they are all touching to some degree in the center of the carrier?

Assuming no issues with this setup, I think it would make for a nice little deer tracking spotlight with 3x 3400mah cells in parallel running 3amp high - 1amp low.

I also bought one of these for $12 something. 58mm reflector should give it some really nice throw.

But that was… the driver? That’s the equivalent of $2 light driver, only blown out of proportion. Not surprised at the 0.9A output. Current is supplied straight from MCU and limited by sense resistor, that’s it.

Driver change would be nice… but the driver compartment is seriously lacking real estate, big disappointment, I was hoping to plug some cheap (but big) ebay boost driver but now that apparently can’t be done.

Still… looking forward to get this one.
