Variable tint

What’s available or potential upcoming with variable tint?
Ideally something for reading or lighting up a room, maybe another (for walking) with throw/flood.
My BLF A6 may need its batteries charged, but I don’t have the charger.

Secondly, maybe variable strobe, of which I elaborate another or further idea below. Get a couple sensors and circuit switches.

How about something connected to a circuit or sensitive touch input to strobe along to some music threshold such as when a single note hits a volume/loud or pitch/frequency or concurrent enough to push some limit that cascades slowly.
Also had some thoughts about how lasers are so very narrow but seem to have some noise, reasonably through dust in the air. I kind of want to pick up some mirrors.

Have a nice time here, Sanman!

Wow, it took you almost six years to make your first post!

Seriously?

Could be a long story and whether it seems serious.

I mean heck, chargers are a dime a dozen. There are literally hundreds of them on amazon for example

Sofirn has a variable tint. 2500 lumens, 2700 to 6500K.

Got one last month, I’m happy with it.

Between $20 or $30 and if it’s not gonna go the same as the other one.
Could keep using 18650 battery then with a Sofirn IF25 or it recommends/suggests a 21700.
Ah, the Sofirn is USB rechargeable.

Anything with a certain sensitive input or fancy circuit rather/instead of how the A6 soft-touch flickers off when pressed (yes, flickers)? I’m looking for maybe something that loops the pattern that whatever I click, it copies and lag/delay, chasing a trail, its tail. Heck then add something to switch it to a second series or play one-single instance. Like a saved strobe you can interact with and add to.
The A6 touches “off” but to the next mode, or a full click.

Or start with a simple adjustable pattern like ‘Bike’ or ‘SOS’ blinkers, but gap between the routine set or stretching out the time of each blink and the set in scale.

About $50 or only a mere $27-30 if skipping the charger.
Sofirn or else…

BLF LT1 has a really nice variable tint
