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

I rather like the P60 format for "general use". More compact, more pocket friendly, and better looking (at least to me). I haven't touched my C8's since about April.

Now to get back on topic: this ZY-T08 is one freaking awesome light! Was playing around with it again tonight and just blown away by its throw! I must have found "Turbo" because it was like blasting daylight. I lit up the backside of a house about 600 feet away and could see every detail of everything there. I then pulled out my Jacob A60 and had a showdown between the two and the ZY-T08 smoked it easily.

I did notice a little trouble with mine not coming on until I gave it a little shake, but after shaking it stays on.

If you haven't ordered one of these yet YOU NEED TO!!!

Preach it brother!

I think you like this light about as much as I do. I got 2 now. And my 2nd one is I’m guessing 5000 lux brighter than my first. It’s a winner. Just a little under my Catapult V3 in throw I would say.

Well heck let me take some 100yd photos if my neighbors vehicles in’t in my way of the trees.

Here you make the call. Manual exposure 1.2 sec shutter f/4 ISO 400 100yds Mouseover ThruNite Catapult V3 mouseout Small Sun ZYT08.

I'd agree with you, just a hair under the Thrunite, although that Thrunite puts out more overall light.

-Garry

I agree. But you got to admit a $26 light compared to a $105 one is very impressive to be this good of thrower. You can buy 4 of the ZY-T08’s for one Catapult V3. But there is no denying the Catapult V3 is the way better quality flashlight. But you got to love that ZY-T08. The Catapult V3 has a lot more useable spill and is putting out more lumens.

Did we ever figure out how to get to the hidden “TURBO” mode? I have two now, they both perform the same. Tried shaking it, thinking the word “TURBO” in my mind really hard before turning it on, tried to see if I could loosen any part of the head to maybe access a second set of modes.

I still don't know how to get "Turbo" on purpose. Perhaps it is a funky driver that goes direct drive (but wouldn't I get way more than 4.0A on direct drive with two Panasonic cells?). When I was using it last night I was in "high" and it was fairly impressive, but then after going through the modes and/of turning off for a few seconds then turning back on it kicked into "Turbo" and I was blown away - definitely a difference in brightness. I left it in "Turbo" for a minute or two and never saw any ill affects (no turning blow, smoke, etc . . .). I do wish my "high" was consistently the 4.0 "turbo" level.

HD2010 & Small Sun ZY-T08 Size Reference:

-Garry

Which light explodes first when you turn them both on?

Well, the HD2010 doesn't work (awaiting modding), so I'd say the ZY-T08 would burn a hole right through the HD2010.

-Garry

Ah, good size reference—totally manageable.

that way from what I gather the biggest difference which is in the tubes is compared. If ya can’t stack em’ then side by side will do. And while you’re at it a head-on reflector comparison would be just capital. I can’t think of any other menial PITA tasks at the moment to burden ya with. :smiley:

LOL!!

I agree with the pic recommendations! ;)

Ok, I’ve not had chance to put thoughts to electron yet, unfortunately real life got in the way.

Anyway, I picked up my zy-t08 this morning, first bug bear, I got stung with customs, £3.21 in vat, then £8 in handling charges……I’m currently considering picking up where Guy Fawkes left off in that respect.

I’d charged a pair of cells last night, incase the mystery package was the small sun so at 7.30 I was at the post office, cash and card in hand, ready to grab package and get on with work. Package open, cells in, yep it works, not as intense as I’d of liked, but hey, suns been up an hour, give it a chance.

Later on in the day, I had time to strip the tail cover off and take some readings.

First issue, two of the cap head screws are almost round, cheap crap stainless screws. Got them out, the switch board is held in with two counter sunk Philips screws, they don’t need to be counter sunk, the board isn’t and ones looking like it was knocked in at 45 degrees with a hammer……with a sinking feeling, I apply the leads to the switch :-

1.92a high
0.92a medium
0.44a low

The clamp meter confirms its under driven, hunted blf for viffers mod, then popped the board out for a look. At this point you can guess how pd I was to discover the board wedged with a piece of thick paper, without it, its a p* fit.

The light looks nice, it feels good in the hand and I’m impressed with the job it does with these limitations in mind, I’d just hoped for so much more. My thoughts at the moment are redrill and tap the tailcover screws m3 and fit some decent screws, and wire a 0 - 0.5ohm pot across the sense resistors, there’s plenty of space in the driver cavity to hot glue the pot in place, then I can dial in the current before finally soldering the board down.

I like it, it just could have been much better with a little care on final assembly.

Here's some more shots to give you an idea on dimensions of the light.

First up is the side-by-side with the ZY-T08 showing the thin side:

Next two shots are side-by-side showing ZY-T08 with batteries in parallel:

Last shot is showing the business ends side-by-side. Same diameter, but the ZY-T08 is just slightly deeper:

Finally, a really bad 'grey wall' beam shot; ZY-T08 on the left, HD2010 on the right. The Small Sun's hot spot is just slightly smaller and ever so slightly more intense; The flood/spill area of the HD2010 is slightly larger and brighter. You can also detect a slight tint difference - HD2010 is cooler.

Did you get yours from DX or MF? Crossing my fingers here 'cause I just ordered it from DX two days ago.

Manafont, quick delivery but I suspect all these hosts are uf-v60 rejects tbh.

Sorry to hear that yours is driven even worse than the "normal" 2.4A. If you see the same value sense resistors, how can it be driven any less than others with the same value resistors? I don't get it. What about cleaning threads and contact points?

At least I can tell you that you won't be disappointed at all once you've cranked up the amps!

Some comments on Turbo…
I got well over 3A on full batteries measuring without the tailcap. Just head and batteries…
BUT: I sometimes got just 2.00A on High when cycling through modes :
Most of the time I got the 2.5A-3A or something like that.

Garry: try to check if your PCB is clean and pill PROPERLY screwed down. Body / tail connection has to be clean also.
Next I will try to measure through tail switch.

Thanks very much! Frontpage’d and Sticky’d.
