The Small Sun ZY-T08 has been listed on China Electronics online store Aurabuy for a while, it has been one of the most popular LED Flashlights after it publised. Nice format, comfortable to hold, secure grip. And the most important is its extremely great throw especially with only 635 lumens, lot of threads on pill for decent heat conduction to head. Excellent reflector, even though it is resin based. Nice switch feel and thick, supple switch cap. All of these features makes it a helpful tool for lighting uses.
The Small Sun ZY-T08 Appearance
The machining and finish on body and head are excellent. No sharp edges and the large smooth surfaces show the smallest amount of machining if you look very close. The anodize is good, probably HA-II quality, with no dings or scratches when received. The gadget comes with lanyard. No spare o-rings. Fortunately all were in place and intact and no spares were needed. With only one o-ring in it's design it probably wouldn't have been needed. The lanyard is not bad. It's good to see better lanyards being included with the more recent torch offerings. The well designed reflector surrounding the perfectly centered emitter. The emitter is centered with a nylon centering bushing. Plenty of fins mean lots of surface area to help wick away the heat produced by the XM-L emitter. Another shot at the fins surrounding the pill.? Deep fins and plenty of space for air to flow through them. Machining on the curved area of the body are nice. You can see the grip ridges along the curved sides on the body.
What It Is In The Head
This is a very nice head design. The pill is removed through the driver end. The emitter star was floating with a small amount of thermal compound. Clean anodized threads for the lightly crenelated aluminum bezel. Clean, nearly square threads for the pill at the base of the head. The lens and lens gasket (not an o-ring) fit snugly in the hit with zero rattle. Huge but very lightweight pill. Lots of threads for lots of surface contact with the head to help wick away the heat produced by the emitter. Emitter mounting area is solid and there is thermal grease between it and the MCPCB. Lots of clean threads on the pill. The pill is 32mm tall...it's huge.? The wide rim at the base sits against a matching recessed area in the base of the head. The inside of the pill is cavernous and can accomodate just about any driver you should want to use should the need arise to replace the stock driver. It's 24.5mm deep and 27.88mm across. You could always use it to smuggle arms or even mexicans across the border. There is PWM but it's some of the fastest I've seen in a budget light. Much better than most budget offerings.
Stainless Steel Base For The Switch Components
A look at the stainless steel base for the switch components. You can see all the machining marks. Purely cosmetic but it would be nice if the tooling marks were not there. The switch feel is very nice - light yet firm. The switch boot is thick but supple. It feels very durable. 4 allen head screws hold the tail piece securely to the body. With the 4 screws removed you can see there is a soft rubber gasket between the tail cap and the body. This should provide plenty of water resistance and a small bit of shock protection if the light is dropped on it's tail.? The switch cap is held tightly by a thick, threaded ring.
The Battery Tube
On the ends, you can see the battery tubes and the contact plate. The battery tube is deep and the springs have a lot of travel. Protected and unprotected cells should work fine. Due to a small lip on the pill, flat top cells will not work. Also, there may be a shorting risk with wide flat tops because of the close proximity of the ground outer contact ring. The pill lip actually prevents this from occurring. My solution was a small solder blob on the positive end.
Here are some white wall beamshots, 1m distance, high, med, and low. The hot spot is well defined with a typical XM-L corona. there are very minor thin rings at about 1/3 diameter, only noticeable on a white wall. They appear a bit dim on here, however they should be good enough for a relative comparison.
The Small Sun ZY-T08 LED Flashlight is a very nice light. I has a nice finish (except for tailcap), decent output (better after a resistor mod, see first comment below), handles well, and the price was right. Relic Recommended, especially for flashlight modders. For the price, the performance, and for overall build quality I have to give this light a strong recommendation.
