[UPDATE Sofirn 11.11 SALE; yuji led C01 and SP36 will be available!!!]

Personally, I think this is a great choice. CCT offerings such as this is one thing that has attracted me to Sofirn from the very beginning.
Besides the fact they make a great light of course. :wink:

Keep up the good work Sofirn!! :+1:

The SC31 looks good. I am in for 1. Found a 20% coupon. :smiley:


I love the Sofirn C8F 21700. Truly advanced technology at an affordable price.

Wait, I didn’t know the C8F 21700 also included levitation technology.

Looks like it’s floating at the table.

LOL :+1:
EMALS
JWST
C8F 2170

2 much good stuff! :blush:

Lightning Deal of Sofirn Q8 ended. How many of you get it?

C8F is still waiting for you to order. I know some of them, 30% of the inventory, don’t reach the max 3500LM, and that’s why the price is low. We promise a new driver for you to

replace.

In the C8F 21700, it is really hard to see a difference in brightness between the old driver and the new one, so even the old driver is not what I would call “bad”. :smiley:

Sofirn, it might be best to rate the C8F 21700 lights closer to 3,000-3,200 lumen instead of 3,500. This is more realistic and people will not be disappointed if it’s less than 3500.

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

Thanks for the suggestion. Our way is test the max output for every C8F (21700) light by integrating sphere. I believe the second batch will be okay.

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.

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

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.

We can get it off AliExpress
Longer shipping time though

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

So you don’t have Prime?

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.

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.

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’?
