Zebralight S6330 $235 SOLD
shipping is $30 by Express Mail (DHL or Fedex or EMS)
Or $15 by registered airmail. But it takes time to process shipping. At least one week or more.
It has some scratches but no big dings or dents.
Send PM first.
Considering that the M43 is $158 it will be hard to ask for more then that.
Considering that RMM has M6’s for around $80 is another consideration.
are you open to offers? and then there is the cost of shipping.
good luck maybe somone close by has been drying for one?
send pm offer
I love mine. Its too bad ZL couldnt profit from the S6330 since they were complex and very expensive to produce. I might swap emitters some day if I get brave enough (not an easy task with this light). The S6330 is just on the cusp of being a continuous use pocket light that runs very hot but wont actually overheat (thanks to thermal regulation). It runs on the hot side after 5 min in turbo, is driven quite well with a separate dedicated boost driver channel for each emitter. Each cell is dedicated to one emitter, so you can run it on 1,2 or 3 cells. This light is also brighter with more range than the original SRK (with screw-in emitter shelf and 3 terroid driver).
The voltage of a single 18650 is higher than than LED foward voltage at that output current, such conversion is buck not boost.
Each cell operates an independent boost channel. Cells are not in series.
An input voltage higher than than output voltage is not a boost driver, but buck. We don't care if the cells are in series or not. 4.2V input, 3.35V output for 3A XM-L1, each cell power dependability 1 LED. Boost cannot exist unless the input voltage is lower than the output voltage.
If there are distinct circuits for each battery and emitter, I would expect them to be linear.
Clearly each LED is powered by the corresponding cell.
I would expect them to be linear too, but I have seen an inductor in this photo (not everyone is ready to smack theirs open), so it cannot be linear (inductance) and it cannot be linear with claims of high efficiencies at moonlights and other
modes that have a vf of around 2.0V, you need an efficient buck converter. There are 3 MOSFETs so we can assume there are 3 inductors. The one in the image is at 1.8uH so even if it small it is not a problem. You can even see the 3 separate inputs (3 red wires and 3 black wires)
Very interesting driver design, thanks for the pictures. I was under the impression that buck converters always need voltage overhead. If that is true, what happens when the Battery voltage drops below the Vf? Perhaps it’s a combination boost/buck?
edit: sorry for hijacking the OP’s sales thread.
Nothing happens such thing is less important for XM-L1 with generally lower Vfs. When that happens the light drops out of regulation but that does not mean the light has to go in a downward curve, ,good companies simply switch the mode to a lower one where the Vf is again under what available input is present. As I said before 1.8uH inductors have lower RDSon so even if they are small they are not so bad. Boosting is impossible, Vf of around 2.0V for 5mA and you input 3.3V that is buck, you can't boost and you don't have why to boost.
Let's take an example how such typical buck driver for 3A can't be worse than a Nanjg 105C driver with 0.15V headroom.
Use a typical 6mOhm MOSFET and a 10mOhm RDSon 1.8uH inductor, for 3A the entire voltage drop is 0.036V. Add some sense resistance also, nothing that can go over the total headroom of something like 105C driver.
Now this is 3 times present for each cell, surely better than the linear 105C (0.15V) in terms of headroom and efficiency for moonlight modes where input and output voltage difference is huge making linear drivers bad.
My Zebralight S6330 is my absolute most FAVORITE light I have ever owned. The construction, the UI, the output, the regulation(both thermal, and voltage), and the size make it the perfect go to light for just about any occasion, other than pocket carry.
If it weren’t for me already owning one, I’d be all over this. It took me almost a YEAR to come by one…
GLWS shrike!
I don’t own one, but one thing I find really attractive about the S6330 is safety.
It’s the safest multi-cell li-ion light ever built.
Each cell is on a completely separate circuit. You can run this light with just 1 or 2 cells. You can even mix different battery types and use batteries with different charge levels.
Yup, this is only multicell light where I would feel reasonably safe tossing in any batteries, and letting it run with no supervision.
In a completely, completely, different league from the M6... like comparing a bentley to a ford pickup, yes both are cars, but that's where the similarities end.
If a flashlight has 2 3 or 4 cells in parallel you can run it from just 1 to 4 cells (any number), so that is better than 4 cells in series.
On the S6330 you will run only 1 LED with 1 cell, 2 LEDs with 2 cells, 3 LEDs with 3 cells. Now if you want to mix cells of different models and different charges that is cool for sure.
I measured my original SRK at 2200 lm and 22500 cd of lux before I modded it. I know the S6330 is rated at 2400 lm, but I haven’t found any lux measurements for it. Do you have any?
I always thought the ZL S6330 was really cool, but could never justify the price. I’ve found smaller, cheaper single-cell triples more useful because of the size difference (despite the much shorter battery life). Even my fully-hotrodded ~3300 lm Cypreus was half the price of a S6330. However, the ZL has several features which have never been matched, and it’s the only light of its kind.
I am posting here just to commend the excellent after-sales service of Zebralight.
About 2 months ago, I sent an email to them complaining about my SC600 that turns itself off after only about 2 seconds of use, regardless of mode. I told them the battery is not an issue.
Zebralight USA replied after 2 days asking when and where I bought it. I replied I bought it at HKe and perhaps about 2 years ago.
Their next email did not ask any other questions, they just immediately gave me instructions on where to send the light in China, pay $15 via Paypal for its return trip, gave me an RMA reference number, and promised a turn-around of 2 to 3 weeks.
Well after they received the light, about three days later they said they have shipped it back with a China post tracking number.
Now I have my light back, good as the day I received it from HKe.
Price dropped.
And added shipping option.
