The TK01 is super heavy, and heavy duty. You would be lifting weights all the time.
Tail switch is on/off only the side switch does the rest. Slight twist of the tail and it’s locked out. Also the side switch goes green when under 50% and red when under 20%. It ran on low for 3+ weeks before it turned off. High will run for well over 30 minutes sitting as is before it get very hot to pick up and use.

I equipped a few deputies with them and they all carry and love it. It’s built like a tank with very easy controls. I do recommend an external charger to spare the charging port plug from loosing its water proofing. The smooth stainless steel bezel is solid with a good edge. The tail has three great teeth. It’s cheap enough not to care when using it as a striking tool.
I would buy a external charger like you recommend. I would also epoxy the USB port completely shut and then replace the cover when the epoxy is still setting and then it would be a cheap way to get around a real problem as long as a high quality epoxy is used. Those charging ports are just for sales, and convenience for the user. Not for reliability, but we all know that………………
All true in my experience. Lights good for years and the port cap fails after a few uses.

So you epoxy your USB charging ports?

@texas shooter
This is the Astrolux TK01, a brand by Banggood.com. I just found out about it this morning and have been reading reviews on it. Thanks for reminding me about this! Banggood.com stops selling TK01 on their site, only TK02 and TK03
By the way, @Deputy Dog mentioned you in his/her comment and I thought it’s a flashlight brand/store, for which I google’d “texas shooter flashlight” and there was an actual site of a physical store selling tactical gears LOL Weapon flashlights – Texas Shooter's Supply
Banggood sells it as the FT01 not TK01 and it’s still listed. texasshooterssupply.com is not me, but soo many lovely toys.

On some I potted the electronics all together. Some I just leave sealed. This one I’ll boost then pot but I do procrastinate a bit. Silicone potting from https://www.epoxysetinc.com will cover most of your needs.

Hi,
Does it stay on high until the battery can no longer sustain the output? Also, I’ll be holding it while using, so does the above number still apply?

It’ll run high, 1300 lumens for about 1.25 hours with the Samsung 50E 21700. Holding a light lets your hand act as a cooling conduit as does colder weather. It’s shear mass allows the sitting by itself for 30 minute run time. It could probably run the whole 1.25 hour. It would however be to hot to pick up and hold that way. I live in warm to hot Texas. In cooler Yankee lands it’ll stay cooler.
I see. Thank you for the information!
