This is what I got yesterday. Took a screenshot. Deleted my address
Noticed. Very strange. Must be a glitch in the system. Were batteries involved?
Ordered a holster. First try as accessory on the BLF Q8 page. Said it was sold out.
Second try as accessory on the Sofirn Q8 page: add to cart.
A few minutes ago it is the other way around.
I guess their IT-system apparently has some room for improvement.
But the T&T shows movement on my order 
No, I didn't include any batteries. I sent them a PM, and they said they will look into it.
So, hopefully it will be fixed soon :)
I have the same shipping option unavailable problem, and I’m in the US. Sent an email to sofirnlight@gmail.com, haven’t heard back yet.
I worked with Sofirn tech support, and now shipping is available to my home address in the US. If the site hasn’t worked for you before, try again, I think they put in a systematic fix.
I also confirmed that the shipment will be coming from China, so the usual transit time applies.
Thanks for your feedback. Please refresh or clear cart and try again. We reset the shipping settings.
My holster arrived today! Thats 8 days from the ping of PayPal to the ding-dong of my doorbell! :+1:
Can you please tell me the battery life with a 18350 on the SP40.
Unno. Depends on how much you use it.
What is the runtime and lumens on High, Medium and High with a 18350 in the SP40?
Just goggled a review, Review: Sofirn SP40 | Best budget headlamp , and there’s a chart that spells out all that.
I don’t put much faith in charts, etc., because of all the variability.
Quickest example, you using a 3400mAH cell, or a cheapie 2000mAH cell? Right there’s almost a 1.5:1 difference.
Yes, I’ve seen these charts but they’re all for 18650 batteries.
You can cut them proportionately, but that doesn’t take into account voltage sag, etc.
[quote=Lightbringer] You *can* cut them proportionately..... [/quote]
Lightbringer told me to do it
Hey, how do you think I get odd sizes like 18420s?
So your battery is a bit long ?? no problem .
So what is the runtime and lumens on High, Medium and High with a 18350 in the SP40?
Runtime depends on the capacity. Lumens depends on the voltage.
Its a 18350 1200 mAh keeppower battery.
I tested my SP40 with a Keepower 1200mah 18350.
I got around 6 hours on medium before the battery was drained.
Idk how consistent the output actually was. But to my eyeballs there was never a step down.
This wasn’t a highly scientific test and I only checked medium mode. I was curious because i was about to take the light on a trip. I was only after a general idea of runtime.
