noob question:
is there low voltage protection on the driver for the jet-u? or is it not needed since it’s just alkaline or nimh AAA batteries that will be used in them?
noob question:

It’s safer since the boost driver requires certain voltage to work. AFAIK it’s approximately 0,7V. So when your battery reached 0,7V the light is simply turned off automatically. As for leaking primary batteries, at only 230ma, there’s less danger to leak Alkaline primaries. But long storing could still leak them. I suggest not to use anything else other than rechargeable NiMh.

230mA to the LED, downstream of the boost circuit., but significantly more at the tailcap. Per your tests, where a 750mAh Eneloop was drained in just under an hour, the current draw from the battery is somewhere around 750mA.
My recommendation is to charge when the light will no longer go into high. That will almost certainly still be above 0.9V resting, which is a minimum voltage that has been recommended by some sources for NiMH

Thanks for the correction, yes that was 230mA to the LED. I measured about 1A at 1,2V in the battery side. More current with stock XPG2 (higher voltage)
UPDATE 190425: Soft reminder to those haven’t completed the payment, it’s -5 days to ordering. Please help us remind those who haven’t check this thread regarding the payment period.
Hello, I would also be interested in a Jetusolis, am I too late?
No it’s not. I will certainly will order more than listed. But not too far off. With current list, 80pcs will be ordered. So go ahead make a comment in the Gsheet (link in the OP).
UPDATE 190501: Interest List is now closed limited to max 100pcs.
I will prepare the order in few hours. It will take about two weeks for the goods to arrive and (hopefully) another two weeks for completion. All kit only orders will be processed first.
Nuemtol, please confirm which one is true:
- In Gsheet comment you placed order for (1× 5000K) + (1× 6500K) Jetusolis
- In your Paypal note you placed order for (1× 4000K) + (1× 5000K) Jetusolis
I want to buy an upgrade for my Olight H2R, with some E21A on a VR16SP4 configured to 6V.
But shipping is high, IMO… 8,50USD seems too much for such a light item
Am I missing something ? I could swear I saw only 5USD of shipping last time

Hi all, I don’t have easy access to computer until monday or tuesday, the gsheet will be updated later when I get back to Bali.

Hi, if anyone cancels I will take 1x Jetusolis please. Looks like a very cool light
By the looks of that Google doc, this group-buy is going to become a reality!

Great! I just commented for 4 Jetusolis R95+, 2x5000K and 2x6500K. Let me now the grand total, and I'll make the paypal payment.
PS: how are ordered the modes, is it L>M>H or the opposite?
Rise and Shine my precious...
Price can be found in the Gsheet note (l’ll do it later). Payment please refer to OP, all explain there.
Mode: L – M – H – L – M – H with mode memory
