Review: Small Sun ZY-T08 2 x 18650 (Parallel)

crap i need new batteries if i paln to order one :stuck_out_tongue:
My Keeppower 3400’s are on the way from Bob

Received mine today from DX ordered on 29 Oct. It has the metal reflector. The only things I noticed was that the driver was a little loose about a 1/8 turn to tighten and I wiped the battery contact plate down with alcohol and got some black residue off it. My keeppower button top protected 3400 fit just fine. (Thanks Kumabear) And of course the spongy switch others have mentioned. Can`t wait for dark.

Mario, as I noted in post# 102, after tightening up the driver board, the Keeppower 3400's fit and work fine, so you should be ok.

Oh sorry my bad I missed that post!
Thanks allthumbs and betweenrides for the heads up.

Allthumbs please share your experience when you power that baby up at night (if you have the time)

Thanks guys :smiley:

Anyone soldered a driver yet?
If you have used a pot, what kind of resistance have you used?

I added a little solder to the edge of the driver, to make it a good press fit. No difference in out put, I also cleaned the anodizing where the switch PCB contacts the body, no difference. I fitted a pot, minimum setting was 0.5ohm, that raised the output from 1.94a to 2.43a on good cells, and up to 3a on crap ultrafire Grey’s, guess their good for something. :bigsmile:

I’m waiting for johnnymac and viffer to get back on the readings of the pots viffer found.

Mine read 0.45 ohm - 49.5ohm in a 270 degree sweep.

The ones viffer found are rated 20 ohm and and 22 turns of adjustment - much better resolution.

You definitely need to get closer to .22 ohm.

Let us know if you find something. I’ll probably be ordering weekend after next (payday).

OK.
While waiting, I tried it blindfolded with one 0.22Ohm

Now I get figures around 2.5 -> 3.2Amps or something like that.
I get once and a while the lower 2.4 something and when I cycle modes, it gives over 3 Amps.

Still I think it got better.

edit: those are with Trustfire Flames. Too bad I just ran out of proper Xtars, I will have to re-test when I get them again…

Viffer said something about the circuit being very touchy with regards to resistance, so not too good cells give a higher reading.

I did find out I have to order some Panasonic’s or sanyos, the cells I thought were good have touchy protection circuits when you get over 2.2a. :frowning:

Got mine today.
Measured sometimes 2.7A, sometimes 2.0A on high (0.95A/0.45A for med/low)
Flux: 660lm/320lm/150lm
Throw: 33kcd/370m

Unfortunately I don’t know what current the light used at those flux and throw measurements, but the flux measurements didn’t have much variance.

Hm. I wanted it to be on par with the FF STL-V2 and sell that one (because I prefer the T08 form factor), but now I can’t. I’ll probably try to mod it (when I find time for it).

If someone of you guys need a 0.22 Ohm resistor but don´t want to wait forever ordering from China or don´t have Electronics shop near you, PM me.

I can send some of those to you, probably won´t need all 20 anyway :smiley:

this is mine coming from manafont today. :smiley:
what do you think, is it a plastic reflector or alumunium reflector?

also my evgreen flat top battery wont work on this flashlight,

so i’ve been thinking to get this one Sanyo UR18650FM 2600mAh Li-ion or this one Panasonic NCR18650A 3100mAh Li-ion or i should go with the unprotected one.

which one would you suggest better for small sun zy-t08? :smiley:

H) :beer:

Plastic. Any button top cells will run this, but the smaller the button the better.

Don’t worry about the plastic reflector, it works, be happy.

now im really confusing about what battery to buy, not the very expensive one i think

what about this http://www.manafont.com/product_info.php/efest-sanyo-protected-18650-37v-2600mah-rechargeable-battery-pairset-p-11591
or

The above mentioned ebay pot looks good. 360° full turn -> 0.7-0.8ohm, minimal resistance ~0.03ohm, max ~19.3ohm,

Thanks viffer, I’ll go find the link again and order a few for stock.

Edit :- just ordered 8, £2.54 8)

Can’t wait for them to arrive now, give this light the current it deserves. J)

Mine arrived last week but I haven’t had a chance to install any of them in any lights yet.

There is an ultrafire version which is the same as the small sun at Banggood for $24.99

Is that yours or a stock photo? If it's yours, any report on tailcap current, build quality, etc . . . ?

-Garry

It's mine, same as the Small Sun 2.02amps on with one battery.
