S2+ comes in either. And 18500 I think. You're just looking at the 18350 listing.

Oh

@timsandtoms explain to a retard pls

T is the brightness? So T6 would be the brightest one?

Color temp

LEDs get sorted into different bins based on what color they are and how they perform, the Emitting Color option is which bin you're picking. Couldn't tell you specifics, read the description or link me the listing. 7135 has to do with the circuity involved, and I haven't delved into driver design much yet. @Sapharanth mind explaining?

I think more let's it run brighter but less efficient?

Pottery

Right on, so you're just picking color temperature. Ever bought lightbulbs?

Lower is more yellow(warmer), higher is more blue(cooler). And cooler and warmer don't make sense because they get the numbers from if something was this temperature Kelvin, it would glow this color.

But thas how it goes. Around 4000-5000 is usually considered neutral, higher is cool, lower is warm. Generally speaking.

If you don't know or care, get 5000k, the T6-3B. Bluer SEEMS brighter. Although, arguably, blue makes it harder to see. But that's really only noticeable, and only barely, on crazy lights that are going multiple kilometers.

But 5000k will seem awesome and bright without seeming overly blue, most would agree.

fuck I wanna buy this thing but I forgot what website it was from

It was like

A microSD card holder in a keychain

And they had one in a swiss army style

Yeah, I guess I'll go for T5 or T6

They have a very barebones website that has asterisks

Found it

I want this

$23

@timsandtoms each amc7135 : 350mA to the emitter on max mode

Lumens increase greatly with current, but taper off from a log curve to linear

And 2.8a isn't worth it, the brightness isn't much better when compared to 2.1a

But of course heat and power consumption increase

Right on, thanks.

So @Millwood, you'll get around 1h15m runtime on max. Probably more.

@Krieger The Viking Plague Doctor you sure the chinks don't make that? because the "shell" of that thing can be bought on Ali for like a few dollars at most.

I hope the chinks make a version of this

sorry for mobile link

finding an insert for cards and shit might be more complicated

but even then 23usd seems like overkill

Sometimes I wish I had a 3d printer

same

It really is overkill, it's why I haven't bought it

Are 3d printers still like 2 grand for decent ones

@Krieger The Viking Plague Doctor you can get great ones for 300 already
