I updated my 4000K 219C with a 5000K model on a Sinkpad. The tint is a more neutral white, which is preferable to the warm white of 4000K. With the Sinkpad, there is no problem with blue shift or smoke driving it at full tilt. 2.80A is actually an underestimate as the light is visibly brighter when shorting the multimeter leads.
Great mod testedandbaked 
Now that you have tasted these crazy high output from a AAA light, you have to test out the XP-L V6 3D 
you did prefer the 5000K Nichia to the warmer one and the 3D is very close to the 5000K but it is more efficient at least at start, but the Nichia probably can sustain a higher output for longer with its lower Vf at turbo.
But if you manage to fit 22awg or even fatter 18awg wires, at start you should be looking at well over 1000 lumens :bigsmile: from that tiny light. Of course dropping like a stone 
but i never get tired of that much light from a such a tiny light.
EDIT hmm, i forgot about that the Tool uses a switch, that could limit max amp a bit from twisty AAA’s.
If you need a 10mm sinkpad, you can always cut or sand down a 16mm noctigon, i used that before i even knew about the 10mm sinkpads.
Great light! I will try to copy if I get back to doing SS-5039s. (But I am not keen on programming my own chips. After a hundred or so computer languages and systems, it isn’t fun anymore.) It is almost an A6 that fits on a keychain.
This is the light of the future. Flashlights will continue to get smaller and brighter.
Amazing mod!
Nice, well documented mod !
What was the procedure to remove the “guts” from the light head?
To remove the pill, reflector and glass, you first take off the head. Looking into back of the head, there is the battery contact board with two holes for unscrewing the pill. Use something with two ends that can fit in the holes (e.g. tweezers or needle-nose pliers) and twist counterclockwise. Keep going until the pill is unscrewed. The reflector and glass are held in by the pill and will just fall out. Be careful not to touch the inner surface of the reflector.
Removing the tail end is very similar; unscrew the aluminum retaining ring, then push out the other parts of the switch by pressing on the button.
Thank you! I thought that must be it, but twisting the battery contact board sounded risky. So I wanted to make sure before I tried it.
Gearbest have a flash sale on the Lumintop tool now only $11.99 i think it is the cheapest i have seen them for yet.
Great price! I bought 3 more. This has become one of my favorite everyday lights yet!
I have been waiting for my tool since July. Every time I contact about my ticket/order they say the item is very hot and they do not have it in stock. Just be forewarned it may take a very long time.
i know that lumintop do not have stock atm…
restock is expected in one week or two (Lumintop not gearbest!)
I just realized that the Lumintop Tool have the exact same pill as my Olight i3S.
That means this pill must be some standard AAA sized of the shelf component, i wish we could buy such pills so i could just do some different versions, without having to buy several lights or take them apart to try a new set up.
And even better someone could be making Lumitop/Olights drop ins with upgraded led+driver
This. In for three.
Interesting observation, didn’t realise that, presumably the OP reflector is the same as well?
Possibly if you post an image of it outside the light we can check, preferably with the measurements also.
If it is we can can probably change hosts with the same pill assembly that would be very nice, to be able to use the same light engine in two of some of the best twisty & clicky 10440 hosts.
But I just have to clarify my statement that they have the same pill, with they look to me like they have the exact same pill, based on the pics in the OP and Vinh’s picture of his Toolvn from his skylumens store. But i don’t own a Lumitop Tool myself yet, so i can’t be 100% sure yet.
It was Tom E’s mod of his Illumina Ti in djozz Nichia 219C that first made me realize the possibility, because that pill is almost the same also.
The only difference i can see visually to the Lumitop tool pill is that the tool pill has two notches on the top.
But who knows the threading could be different if we are unlucky.
Great build, it has inspired me to try this out myself. I’ve only done a LED swap to nichia219b and the tool is already one of my favorite EDCs.
Were all the driver components hand solder-able? Also, I noticed this new driver does not have the holes to remove/install the pill. How are you removing the pill for new mods?
I just finished this mod up with the mtnelectronics 11mm fet driver, nichia 219b on a 10mm sink pad. Everything went great, my pill was glued in originally and was a pain to disassemble. I took the pill and turned a small piece of copper and pressed it in, then I turned a shoulder on the pill itself about .040”deeper for the driver to sit a little deeper. Then I left enough leads on the LED wires so I could turn the driver up on its side and spread out some needle nose pliers to turn the pill to thread it back in. Works amazing, I love this little light!
You used a pre-made driver rather than building on yourself? You didn’t use a FET + 7135?
This mod requires a lathe? or is there some other way to make it work?
I have the copper tool which is screaming for a 10440 in there since it should dissipate the heat a little better than an aluminum one.
How did you remove the glued in pill?
