got my zy-t13 today. bought this light basically to make the best thrower i can afford for the money.
heres a list of what i plan to do:
resistor/pot mod
crelant collimator head
make it a 1x18650/2xrcr123a
emitter swap/dedome
i am going to need some help with certain parts of this, so i thought i would start my own thread to ask questions as i go. resistor mod will be easy, i already have a stash of resistors and pots from ecig mods thats not getting used so ill skip that question. and the collimator head, again no questions there
so lets get to getting this thing a shorty. i already know that the 7g2cs tube is a great fit. it will be $29 shipped for the tube and switch. i have also contacter a well known member around here with mad skills, and i can get the stock tube cut down and threaded. but the stock tube has bad threads, so id like to find a replacement
anyone with the zy-t13, crelant 7g5cs, 7g2cs or v9cs able to check if they have any other single 18650 tube that will fit them from a budget host?
after i get the other 3 steps done, i will get to the emitter options
ok i mine as well ask this now too.
im not up on all the physics using aspherics. i dont know if dedoming would even have any effect with it. not sure if swapping to another emitter would change the focal point. i know xre was a go to for throwers, but not sure if that has changed since the new crees…
i was thinking either go with an xre or an xml2. but ill ask the experts, and take what advice is given.
using the collimator head, would changing the emitter mess up the focal point? if not what emitter would be the best bet for a budget minded thrower? de dome with an aspheric make any differance?
Pulsar,consider the fact that you want to run it on 1 cell and it may not work right.I know for sure if you decide an emitter swap,you won't be able to use xre,xpg or xpc due to the stock amps being too much for those emitters not bonded to copper.Just some stuff to think about and I have tried to make mine a shorty host with no luck.The closest solution I had was to get a shadow TC-500 1x18650 tube,but I can't verify if threads will work.Just my opinion,get an XML2 in there with a resistor mod and aspheric which will get you a nice fat throw beam.I modded mine to MTG2 and it's a flood monster,so I plan to get another for aspheric mod.
On a single cell, the tail current is 1.89a, on two cells its at .88a. I’ve played with it a bit with my 7g2cs tube on it, but I don’t want to keep swapping them.
Edit: looks like a monster just as a shorty, can’t imagine how bad she will look with the collimator head on
Seems a bit low with 2 cell,I can’t remember my stock output but single cell amps would work fine with xre or xrc.Either of those emitters will give you a nice laser like beam.TBH the .88 amps will be a little underdriven if you want a decent preformer.The other issue you have to tackle is the focal length of the aspheric head of the crelant,even though it fits you might have to mess with the distance from emitter to lens.
Yeah, I got a few pots and a bunch of resistors to take care of the driver. And I’m hoping the focal length is close enough that the adjustments on the head will handle it.
Now testing amps at the emitter, can I just check it with my meter, or should I remove the emitter before testing? Don’t want to prematurely kill anything
Thanks, I’ll make sure I update on all I do to it. From the looks I will end up with the crelant battery tube and switch for $29, but I’m going to get the head first. Just waiting on eBay to release my funds.
Put the ea4 on hold for a while since I think later batches will fix the small issues with it.
Now looking at it, I’ll have about $100 in to this, $70 not counting the battery tube… So I hope I get some good numbers in the end.
I could have just saved up and got something pre built for $100, but I tend to be bad at saving up. And its fun building and having something one of a kind
I already know I can get it done, but the threads that attach to the head are crap and that part is a hexagon shape. That and between shipping and the lathe work and Crap threads, I’m almost better off getting the crelant tube
I’m planning on running just 1 18650, but I’ll have to wait and see until I do some more testing with it. Seems to work atleast as good as two, but I may be wrong. Want to check amps at the emitter too.
I think it’s a pretty Damn good looking light as a shorty too. But everything but the part that holds the pill, driver and side switch will be crelant parts… So maybe I should have just bought a 7g5cs? Lol. Working on a deal for a collimator head, tailcap and battery tube right now. Hope to work something out
On mine I measured 3.1 amps at the emitter. How are you measuring it? I'm going to guess you are just shorting it and you didn't desolder the LED wires?
