Astrolux ec03 ramps down after about 30seconds -help?

Hi - I’ve had my Astrolux EC03 for a few years and been fine. I’ve noticed the past few days I’ve got the light ramped up as normal when out walking the dog and then it dims down or ramps down to about half power/brightness. I can push it up again and then it goes down again - around 30seconds I think.

Is there any way to resolve this?

Thank you.

I hope you have fun here, sds872ssdhskjd!

Welcome!

You might need to calibrate the temperature again.

Type Andruil 1 temperature calibration in YouTube

Or try a reset by loosening the tailcap and then press and hold the switch and tighten the tailcap and you should see a couple of flashes which means it’s been reset and the factory temp I think is 45c or 55c someone here has better knowledge than me!

Give it a go and let us know!

Thank you. I did the reset (loosening the cap) but this has not resolved it.
I did search in Google but I can’t work out what to follow there.

Any thoughts? Thanks.

Its supposed to ramp down but how do you know its by half? Did you try another battery?

Before when out taking the dog for a walk there’s a lane I’d walk up without any light and normally the torch would light the entire road all the way. Now it lasts about 30seconds and I can’t see much - maybe it’s around half way or a bit more - it’s not bright at all so I think about half as it’s still giving off light suggesting not all the way ramped down. Battery charges fine and stays fine - I will order another battery and try that as well but don’t think it is that?
