Thanks guys and HKE. I tried with the fully charged cell and yes it went to the turbo mode.
Great
it looks like mine is coming either today or tomorrow 
this is my cheaper and hopefully more reliable option to the zebra sc52w
It pains me to hear about all the issues people seem to be having with various Zebralights these days. Hopefully the fact that both the SC52 and SC600 have been on backorder for so long is an indication that they’re trying to iron out the bugs before doing a new manufacturing run. I’m really looking forward to getting an SC600W L2 MkII one day.
yeah i want one of those too - on illumination supply they said the new shipment has different coloring in the annodization between the tail cap and body 
I have had 3 zebras in the last 2 years and all of them have had QC problems… flickering on low, switch failure, horrible tint, off center emitters… i still enjoyed them to some extent though… i wish i could get a good one lol i think i have bad luck
I got mine today. It arrived in great condition. Had a quick play with it and all seems okay.
Some quick observations:
-well built
-good and simple UI
-push button slightly raised, and tailcap has a small flat area, making only tail standing possible (though not the best stability)
-tint warmer than expected, but still quite nice
I really like this light after playing with it a few times today. Nice build quality and I love a lot the brushed finish on the surface. The NW tint is simply gorgeous! The mode is simple enough but my only gripe with this light is it can’t continue to cycle between the mode after you release the button. It has to start on the first (lowest mode) again.
A cosmetic issue like that probably wouldn’t have stopped me from buying one. But that backorder status is difficult to circumvent 
I agree with you about that. But even my SC600 behaves the same way, and I would assume that the SC52 does as well. Maybe it isn’t easy to make a driver that with mode memory and cycle-point memory (or whatever you want to call it). Or maybe the bias toward the activation of the lowest mode is intentional.
Mine arrived today too. It came in perfect condition. For me, I love that the cycle always start on the lowest mode. Anyway, I prefer the warmer NW tint of my wizard pro to this spark NW.
I also ordered the wizard pro wide nw
Buying spree? :money_mouth_face:
yeah, ive been on one for like the last month and a half lol.
Got my SF3 NW today and I couldn’t be more pleased. Super fast delivery, great price and it arrived in perfect condition. Everything is right on: good tint, fit and finish, centered emitter—everything. A few small glitches in the carbon fiber band is my only real gripe. The light itself appears to be superb. If only I wouldn’t have jumped ship on the SF5 to save a buck, I would have it now too. My WallBuys SF5 shipped a couple days previous to my hkequipment order and the SF3 still beat it here.
Great job jmpaul320 and hkequipment, and thanks again! This is also my first order with hkequiment and I’m really impressed.
I have a question for those of you who ordered SF3 can you guys running the light on turbo for more than a minute without any flickering? I don’t know how to describe because it is not a step down, more like a PWM. It could be the cell but I’m not sure.
Please henceforth just tell us the lights you don’t buy. Shorter list 
I spent some time testing with a few various 16340 cells and couldn’t get mine to do what you described. I didn’t test it with a meter, but I can tell it’s pushing the battery pretty hard, and I could get it to trip the protection circuit on a couple cells and shut the light off. It does seem to step down after about a minute. Once I thought I saw what you were describing but I put it on my phone’s camera and it could see it. In fact, my camera shows that my SF3 is quiet as a mouse with respect to PWM or circuit noise.
The SF5 NW just came in from WallBuys today. It shipped a couple days earlier and arrived a day later, so hkequipement is the shipping winner here. Both are fantastic lights and I’m so glad I put off buying an SC52. The SF5 NW has a slightly warmer tint than my SF3 NW and I like it!
So far the photos are coming out nice. Here’s a teaser shot:
I tried again draining the battery but this time only on high. The protection tripped after 55 minutes without any flicker or noticeable step-down. Comparing to this graph taken from a review, the result seems spot on. I may need to try again to see if there any in turbo mode.
Do you have an idea on the current which the led is driven at?
I’d like to replace it with some Luxeon I have.
Mine arrived today. I ordered it on the 8th, so that was fast.
I’d like to thank JMPaul and HKE for doing this. I arrived in this thread after the GB was already going and they graciously allowed me to get in on it.
I ended up getting the SG5 headlamp, but given the build quality, I only wish I’d give into temptation and gotten the flashlight as well. I’ll post up a picture some time this weekend.
Thanks again, guys.
I got my SG5 today and I can say that I am impressed. I just wish that I had also ordered a flashlight as well.
Ordered on the 8th, received by HK post on the 10th and in my hands in Florida on the 16th. The best service that I have ever received from China.
HKEquipment has certainly moved up near the top of my preferred dealer list.
