i personally do not want to futz with my phone to get light
by the time i can get it out, and get it in the right mode, i could have also found my flashlight and switched it on
also the phone itself has a (bad) flashlight
it;s the same reason i wear a watch - it is just better actually checking the time than looking at the phone

At no point was that the suggestion wle. 
the idea was the light would function as a normal light but be able to be adjusted on an app too, if the user wanted to.
It’s not the idea behind this thread but I just wanted to say that I very much share this sentiment, that devices that seek to replace multiple dedicated devices feel like collections of compromise. Phone sucks at telling the time at a glance, sucks at being a light, usually sucks at playing music and it’s why I wear a nice watch, carry a torch and there’s a Rockboxed Sansa player in my bag. Plus if one runs out of charge I can still use the rest. When your phone dies and it’s all you have, sucks to be you.
On an app controlled by what? Again you have to be within range of your constantly on listening device for an app to work by voice. Are you going to tell us what headlight you were using?
foursevens had this at least 5 years ago
app controlled lights
i would have got one, before anduril etc, but the lights themselves were very expensive, and used cells i did not agree with
it may have been the ‘preon’ model
bluetooth control is not that expensive or hard, yet it seems to have failed market tests
you may want to research what foursevens did, to see if it could be improved

on another note, actual voice control by just the light[no phone involved] is probably beyond any processor that you would want on a flashlight
ie too many resources, too expensive, too much battery, too many peripherals needed [making light too big, battery life short, ]
it would practically have to run android to have decent voice
just food for thought
i could be wrong
but it takes a lot of fast processing to do voice
wle
Do you really want a device listening 24/7 what’s around? lol
NO
There actually are dedicated voice recognition chips if you’re fine with finite set of commands and don’t require the ‘natural conversational control’ of Al(l hearing)exas and similar.
A while back I’ve actually drunk-impulse-bought a voice controlled multimeter for the meme. It’s a shitty meter and it cost like 20€ but the voice recognition actually works as advertised. But, and this would apply to a torch as well, I wouldn’t ever want to be seen voice-controlling a meter (or a torch) at an actual job site or in public in general.
so how could that be part of a flashlight design?
would you just say “execute A” and A does light function 1?
how much current at what voltage do those use?
guessing they need 5V
wle
can we get the OP started on his design somehow?
what happened with the lenser light or app, or whatever that was in the first post?
No idea on electrics, I’ve never used them in my designs nor felt the need, I don’t like talking computers nor talking to computers.
But I could see commands like ‘turn on’, ‘switch to flood’, ‘switch to throw’, ‘brightness up’, ‘brightness down’ etc.
My thoughts exactly.
A bear to bear kind of understanding. I love it.
Believe it or not I think the first Bluetooth-controlled flashlight debuted at FastTech and was announced right here on BLF in 2013:
I’d rather have a light that actually works than some bluetooth app phone voice spyware security malware rubbish.

what is happening and why is there a GIANORMOUS THUMB all over my screen all of a sudden
