I have no idea. I’ve been trying to get confirmation on a variety of extras… but most of those questions just disappear into the void. In particular, I’m hoping there will be a diffuser cap made to fit it, to allow it to work as a candle or lantern. But I get the impression this sort of question won’t even be acknowledged until after the light itself is in production.

Very excited to finally see this come to fruition! Can’t wait to be able to order mine. I’ve got the money reserved Big Smile

I get the impression that you have the patience of a saint.

Justanotherguy brings up a good point, you never know what spare parts you might need. I think I should get the complete master set of spare parts.

Could I have another light please? First one is at 1877.

If no logo is possible for the GB production, I want two, total, for sure.

I don’t mind the bunny, but I don’t prefer it, either.

It is confirmed here in the thread there is no bunny on the GB lamps.
I also mailed Neal and he said no bunny.

After the group buy there will be one on the tail.

Could someone here do me a favor? Please remind Neal that I still don’t have the two GT Micro’s I paid $90 for and the Fireflies E07 he sent instead is still sitting here waiting for his response from a month ago.
Thank you.

I would hope he is following this thread, and that should be a reminder, but if you are waiting for a response from a month ago, I’m probably wrong.

I’m planning to mod one with Nichia 219B sw40 as well, so I’m also following closely on the discussion about disabling the fet. Can it just be a setting instead of hard coded into the firmware?

219B sw40 can handle the turbo on my FW3A just fine when using a somewhat used Sanyo GA. The tint is much less pink in relation to other modes than with some other 219B lights on turbo, such as E07 and ROT66 with more potent batteries.

Thank you Tatasal, Neal sent me a PM and reports that he will send GT Micro next week. Now I get to see if he sends one or the two I actually ordered. Smile Life is a mystery, flashlights make it an illuminating experience. Big Smile

So looking forward to this reaching fruition!

This is my second proper group buy and the unfortunate thing that really stands out for me is that by the end of these projects some people are really really mean, and for no reason.

Being in SA I’m hoping the courier is reasonably fast Innocent

Put me down for a 3rd light, please. I decided to get one for a friend, too.

Thanks!

Originally I thought just one of these would suffice. I don’t know what I was thinking… I am in for a second one!

Just to clarify for people in the FW3A group buy, this battery does not fit into the FW3A. It’s completely unrelated.

This. People have made dozens of 219b fet triples not sure why the sudden concern with a mid drain battery?

I’m fairly new to modding lights, managed to find some sw45ks, and just don’t want to take any chances with them.

Forgive any ignorance, but wouldn’t a new, fully charged, Sanyo GA still pose a risk? It’s rated at 10A, which is over the maximum current when split over three LEDs. Please let me know if this is way off base.

That’s not how it works. The 10A rating for the GA is the maximum safe continuous discharge current for the battery as rated by the manufacturer. It’s a safe operating limit, not the maximum possible current. A dead short would produce many times that current, probably until the cell got hot enough to be limited by its internal PTC thermistor, or until gas is produced, triggering the current interrupt device and permanently disabling the cell. If you’re unlucky, neither happens and it enters thermal runaway and explodes.

Current through a FET driver light is determined by three things:

  • The forward voltage curve of the LED. Here’s a test of the 219B R9080 with a forward voltage plot. Note the peak output of 700 lumens occurs at 4.0A, well in excess of the rated maximum, which requires 3.3V.
  • The resistance of the circuit, including any springs, leads, traces, and the FET itself.
  • The internal resistance and resulting voltage sag of the battery.

If the actual current is 10A or less, which seems likely with 219Bs and a GA in this light based on my experience with other FET driver lights, it will be fine. Most LEDs can take far more current than they’re rated for without acute damage, but with more than 3.0A per 219B, almost all the energy goes in to producing heat rather than light.
