SOLD - Modified Jobsmart Flashlight - 3AA XM-L T4 Copper Heatsink Custom Paint

Hey all Y'all,

I have a mod that turned out to be one heck of a thrower and doesn't break the bank. Some of you might remember that I bought a couple of lights from Tractor Supply (Jobsmart brand). Well this is one of them. It is a 3AA light similar to the Saik.

It is all aluminum construction with a SMO plastic reflector and plastic lens.

I removed the original led and made a new heatsink out of Copper.

I put in an XM-L T4 (5,000k). It has two modes OFF & ON. No circuit board here. I'm going to continue to do DD lights for a while. Less to go wrong!

Uses NiMH or Alkaline batteries. For the shots I did tonight, I used Alkalines.

Edit: It comes with the 3AA holder. It's a stock Chinese 3AA holder. The resistance in the holder actually benefits this direct drive light, due to the low vf of the emitter, it helps tone things down a bit, especially with Alkalines.

Here's a couple of photos and of course, Beam shots to show how well it throws.

The paint is the gray textured that I have used before.

Here's a control shot, before I turned the light on.

The shot above shows just how bright this beam is. The one below really illuminates the tree, at about 40 yards. The difference is night and....... Day!

Again, a Control shot, across the pond.

The upper shot is across the pond, at 50+ yards.

The lower one is at the end of the pond, pushing 90+ yards.

The "white wall" shot. My garage door is as close as I get to a white wall. Distance is about 7 yards.

Thanks for looking!

I was surprised at how far this thing throws. My poor photos don't do it justice. The photo of the farthest distance was not near as bright as it actually was. I could see the whole bank and tree lit up there. Could have seen any animal or human skulking, if there had been one.

How many lumen does it throw approximately?

I cannot measure lumens, but from making so many XML-T6 lights, I will say that this direct drive T4 is every bit as bright as a T6 running with a driver board. I was impressed at just how bright it was and I do believe that it is being pushed (voltage wise) with the alkalines I tested it with.

It's far brighter than the sun on a cloudy night.Wink

I'm surprised by the throw, too.

Did you stick with the original reflector?  And is it the same as the Saik reflector?

 

For me, the Saik's relfector + XR-E makes for useless flood and tiny hotspot.  I'm looking for a reflector before I start my mod.

 

Nice mod, as always!

It's not the same as the Saik reflector. It seems to be deeper and yes, it's the stock one. I was trying to keep the light budget and when I saw the beam, I decided to keep the stock one.

It's hard to second guess reflectors since none of them list the degrees in the descriptions, but basically (very basic), a deep reflector will be a better thrower and a shallow one will be a better flooder. If the depth is the same or longer than the diameter, it throws and if the diameter is much larger than the depth, it floods. It's just a generic broad based statement. I imagine more knowledgeable members can tell from the OD/Depth/bottomID just how it will react with a given emitter, by calculations.

How difficult would it be to run it off 26650?

I would have to measure the length. I think it would be too long, but when I get home tonight, I will check it.

EDIT: No way with a 26650. Couldn't even get the cap on with one in there, sticks out too far.

Just got back in town and thanks for shipping the flashlight out so fast.  It is very bright especially on Alkaline batteries.
