Please take a similar action on the C8F 21700 on Aliexpress. Shipping from Amazon is so expensive that the purchase is not worth it.

We want to clear the inventory of 1st batch. The price after code for C8F 21700 kit is only $32, isn’t it good enough? I know, about 30% of them won’t reach 3500 LM but we promise a

new driver for you to replace.

please pm for code.

TexasToasted · 2018-10-30T02:34:14.000Z

Thank you for the Amazon C8F bundle code. Order placed.

ONLY $32 for C8F 21700 Bundle with 4000mAh 21700 battery inserted and coming USB charging slot.

Are you going to be adding built in charging to the C8F?

And then, of course, I’ll have to buy 1-2 of those, too… :person_facepalming:

32 USD is a good price. I think the issue is that international shipping from Amazon US is either very expensive or impossible for some countries. For example, Amazon US no longer ships to Australia.

The price is good. But the transport is expensive. Almost $ 20.

I think the problem is that he’s in Australia (Sillen) or the Czech Republic (Petr J) and he’s trying to order from Amazon USA. So obviously the shipping is going to be higher compared to him ordering it from China which has much cheaper subsidized shipping. Everyone should choose the shipping that works best for them. Don’t choose shipping that is going to be super expensive. This should be common sense.

Maybe Petr J is getting high shipping costs from Aliexpress due to him being in Czech Republic? I’m not sure.

HONDARIDER · 2018-10-31T03:43:47.000Z

I was under the impression the 21700 C8F’s from amazon were the units with the good drivers. I ordered one to compare to the 2 I have. Sofirn has replacment drivers on the way so I guess I need a 3rd driver. I thought the issue was fixed. Oh well, guess I will contact Sofirn if it does not reach 3000 lumen. The 2 I have didn’t even test as bright as my 18650 c8f’s.

Lightbringer · 2018-10-31T03:56:33.000Z

No lumenometer, so can’t say how bright mine is, but I did notice a bit of an “upward fade” when I kicked it into turbo.

Does that indicate an old driver that needs a fixin’?

No, they all ramp up slightly on turbo.

The difference between the old driver and the new driver should just be the MOSFET. The one on the old driver has a little bit more resistance in it so it doesn’t draw as much power on Turbo. I got 2 extra amps on turbo by swapping to a better MOSFET.

If you are not located in USA or CA, please purchase for aliexpress store. 11.11 day is coming, the price will be great.

Kewl, I’ll leave it as-is, then.

JasonWW · 2018-10-31T18:45:06.000Z

SKV89 has replaced his driver with a new one from Sofirn and saw no difference in lumens. ???

sulfur · 2018-11-02T06:05:23.000Z

Thanks again for the promo code Tracy. Looking forward to my 1st Sofirn.

You’re right. The cost of transport from Amazon is high. When ordering on Aliexpress there is no problem. The shipping price is low. That’s why I buy Aliexpress. I already have a flashlight in your cart. Sofirn is a very correct company. I have about ten flashlight from Sofirn.

I gotta ask, as I’ve seen them around forever… and it’s been bugging me just as long.

What are those “1 USD” and “Price different / checkout link” things?

What are they used for? How are they used? Etc.

It is just for buying misc things that might not be listed or if there is additional shipping costs due to the buyers location. So if an order needs $4 more added to it, they can click a quantity of 4.
