Jetbeam BC20-GT - how long can you run on high mode?

Hi all,
I’m a noob to flashlights so to speak. I’m thinking of getting the Jetbeam BC20-GT because it is simple to use.
Just wondering if I turn it on high (1080LM). Can I just leave it on high or will I be forced to manually set it to low mode, or will it automatically switch to low mode? If automatic, how long will it run on high for?

Thanks

i have one, and you need to know there are only 2 modes, you should consider getting another

OK. Thanks for the feedback.
I’ll look at other options.

Much appreciated.

agree
the modes are both useless - way too high, and still too high!

get something by convoy
or astrolux s1, blf a6 - same thing

Does it have a memory mode or always starts on High?
