I filled out the form this morning. Anything I need to do except for waiting for the code?

You just need to wait for Martin to send you the purchase info. He’s in Austria so he might be asleep right now. Are you in the same time zone?

Still, if you signed up this morning it seems like he should have sent you the info earlier today. There are plenty of lights, so no need to rush. I’m sure he will contact you soon.

Well, yes…actually Austria and Germany are in the same time zone and very close together. We even speak the same language.
No need to rush…I can certainly wait. I was just a bit suprised how many people wrote today something like “yeah, just ordered”, so I was wondering if there’s anything else to do from my side.
Thank you JasonWW!

Cheers,
Thomas

I’m still looking for a runtime on high estimate - would this calculation give a good approximation? 3000mah = 3ah, 3ah/4.5a = 0.66hr, so 40min on high.

Thanks Jason,
I was just wandering if there would a big difference between a sanyo GA and Samsung 30Q. both unprotected.

There is a bit of difference since the 30Q is a high drain and the GA is a high capacity.

I like to use HKJ’s battery comparator. Load up both batteries, set it to show 5A and you can see that the 30Q will have less voltage sag giving you more regulated run time. The GA will give you more unregulated runtime.

In the real world you might not notice these differences. Both are good batteries.

I would stay away from the Panasonic NCR18650B, though. I had this picture already so I figured I’d post it.

Even at 3A, the Panny B has big voltage sag. At 5A the sag is even greater. The GA, 35E and MJ1 are all good high capacity cells if you need max runtimes down to the low voltage protection.

I prefer sticking to high drain and swapping batteries once it gets down to 3.7v or 3.6v.

Do you have an estimate at what voltage the 30Q will fall out of regulation?

[Delta_V]

It’ll be more complicated than that because at some point the voltage will drop below the threshold required to maintain the 4.5A current draw. At that point, brightness will start decreasing, but so will current draw.

End result is the total runtime will be longer than 40 minutes, but the runtime at max brightness will be less.

What protected battery is recommended for the short tube micro?

18350 cells are already way down on power. A protected version doesn’t make sense to use in my opinion. I think the Aspire is the best, but I don’t know if it’s made with protection circuitry.

Maybe someone else knows.

Keeppower 18350 1200mah
they said aspire is from the same factory

Paid earlier today for 1x NW + shorty tube.

Thanks Neal, Martin, and Lumintop!

Do you have an estimate at what voltage the 30Q will fall out of regulation?

No, that’s something Lumintop would have to tell us. They could design the driver to fall out of regulation at different voltages. They might not tell us, but we could still measure it once we get the lights.

Like Delta_V said, it’s more complicated than that. Keep in mind that in the real world thermal protection may activate. So you would measure on high, then turn off and cool down the light, then run on high again, then add up all the run times to find out the total run time on high (within regulation). Is that what you meant? Or did you mean how long it will it run before stepping down due to heat?

I can only say that you will definitely get longer, steadier run times at 3.5A. Also, a high drain battery will stay in regulation longer in comparison to a high capacity battery.

We won’t get any real runtime data until the light gets tested.
