Interest collect for a new Sofirn design: tube style18650, magnetic ring control, USB-C charging, 500 lm max (AKA grandma light)

I am interested,
concept photo would be nice, colors?

I’m afraid that there is nothing yet but specifications. On request of Barry yesterday I made a first structural drawing of how this light could be built and sent it to him. At a later stage I may post the drawing but I must first get the comments of this design back from Sofirn’s engineers, discussing something that will not happen anyway is not so useful.

Interested

Thought I had replied but guess not. In for at least one. Thanks djozz et al. :beer:

HMM I might be in for 4.

at 500 lumens, what kinda run time on a 3500?
( I just found this 350 post thread)

If a high CRI led is used like the LH351D, I estimate about 1.5A to get 500 lumen, so runtime will be a bit over two hours on the highest setting.

Maybe I’m misunderstanding the concept, but will this kind of be like a larger, High CRI version of a Jetbeam RRT-01? If so, I am very interested!

Good question, it depends on how Sofirn picks this up. If they decide for the infinitely variable ring (it requires a different fairly expensive, more than a dollar, magnetic sensor component, and designing the control for it what they have not done before), it is not far from a 18650 version of the RRT-01, albeit with a bit lower output. If they stick to distinct modes (which is electronically different, probably cheaper and already known to them), it may not look to you like the RRT-01. Mind that the distinct modes outcome is still very much within the scope of this project, for the project I would be happy with that (but I do hope a bit for the variable control because that attracts an extra category of buyers). I hope for a few answers after chinese newyear.

Please add me to the list as a possible buyer.

I am interested in 4.

Interested for 2

I'm already in for one, that remains unchanged.

Just wanted to say; the heck with the kids & Grandma!

Mine! Mine!! Mine!!!

That is all.

Carry on.

Put me in for 2

I’m interested in 3, please!

We are at 250 units on BLF, plus 153 on TLF, that makes 403 total.

That should get us at least into the design phase I think, and once a design can be shown (assuming it is good) that will boost interest again.

I hope that China will soon recover from the Corona virus shutdown so that the design phase can get going :slight_smile:

Sign me up for 2. Thanks!

That’s incorrect.

Count me in for 1

I’m interested in one at least
Personal want from wishlist
Magnetic ring, color not black, magnetic base, holster
Thanks

I’ll take two pieces. :slight_smile:
