HS40 and SP40 body tubes can be used interchangeably, as shown here.
(the body tube knurling pattern for HS40 has been changed to a horizontal instead of diamond pattern on the SP40)
HS40 does not come with 18350 tube though (but can use the SP40’s 18350 tube)
HS40 uses USB-C (tested charges at up to 5v/2A - so one shouldn’t probably charge an 18350 battery using this),
(USB C-to-C cable charging is supported)
while SP40 uses micro-USB port.
The store on Ali has an ugly support service.I ordered the HS10, only the LH351D 5000K was available.I asked them: will there be 4000K, to which they replied that it will be in a week or so and they will send it if I am ready to wait.I did not cancel the order, increased the processing time, trusted and waited.The next day after the conversation, my ordered 5000K was sent.They answer my questions and indignations with laughing emoticons!Besides the word - freaks, I have no name for them ...
Usually, Sofirn adds what I ask for when buying, but sometimes there are some miscommunication : either they forget or put something different. But I am happy overall !
(We’ll see if the HS40 and HS10 I just bought from them will come with or without spare LEDs …)
Good afternoon.Received Sofirn HS10 everything is in order, except for the absence of a clip and a lace on the hand.I do not need a lace, but the lack of a clip is disappointing.Useful thing.Reply from Sofirn: "The HS10 does not have clips or laces. Sorry because we made a mistake in the photos, sorry."How cute!
