I tried to order then as well, but the credit card processing consistently came back with a security problem, and wanted me to submit a scan of my photo id, my card, and a statement for that card. I can live with giving them a picture of my photo id, but I absolutely refuse to send anyone scans of my credit card and a monthly statement. Might as well just mail the card to them.
In fact, thatās weird to ask for a photo ID, a photo of your CC and a statement from your CC company. They must be nuts! But Iām sure itās not Sofirn to put the blame on but AliExpress and their payment system that seems to have issues with some cards.
Torture test done. And the C01S seems a bit less robust as the C01 (but N=1, just one sample tested of both). At the end of the test the light did not work anymore, but after screwing off the bezel and back on again it worked fine again.
I think what is going on is that the bezel can be over-tightened, I did that with quite some force (am a bit OCD about tightening things in flashlights) just before my son got it, so that if too tight the bezel touches the battery tube before the driver does. Threadlock btw prevents that . If it happens too easy, an easy (but not goodlooking) fix is sanding a fraction of a mm off either the bezel or the battery tube.
Because of the optic and small-die SST-20, the 2.5 lumen from the C01S is brighter than the 8 lumen C01, I find it not dim but plenty for all things that just needs some lighting up, good for reading too. And the 87 lumen feels very bright, good for searching stuff around the house (likely my #1 use for my EDC ).
I (or someone else) have to do a runtime test still btw, and I suspect that for most of the runtime, with Eneloop and certainly with an alkaline cell (btw alkalines are not really suitable for this light when primary used on high, not enough capacity for the current that is drawn), the high setting is considerably lower than 87 lumen (87 lumen 95CRI would be probably 150 lumen with a low CRI led, so more than 400 mA is going through the led, more than an amp from the battery; it is a pretty good boost driver that is used here).
I know it was AliExpressās problem. Outfits like Sofirn use AliExpress the same way a lot of US sellers use Amazon. They handle the payments & shipping, usually at far less than the seller could do by themselves.
I did a not accurate runtime test with the C01S with alkaline on low, checking after one day and after two days. After one day it put out the same 2.7 lumen, after two days the light was off and the battery completely empty.
In an efficient flashlight I expect 2.7 lumen of 95 CRI light to be caused by about 10 mA, plus 2.5mA for powering the MCU, but that is at over 3V, before boosting that would be 32 mA . An alkaline at low drain is about 1000mAh, so that would be a bit over a day. This is with a lot of approximations but it seems about right.
That looks a new type of diffusor, and it seems like not silicone but another plastic. The length makes for a more even light distribution, more to the side than the short types. Except the Q8 diffusor, that will still direct a lot of light upwards.
3.77 dollar for two tiny pieces of plastic (worth a few cents it looks like) is too expensive. I want to hear of some pretty awesome features before I buy those.
nice :sunglasses:
I was going to get 2 C01s along with a few other lights during the big AX sale.
But in that case wil hold off on the 2 C01S untill we can get the BLF edition
Hi Barry, they look good and look like they will diffuse well. Looks like they are not made of silicone but a harder plastic, right?
I think the price is too high, especially the small ones may not sell well because of the price.
