I agree with your comment on the charge level indicator. It is a very poor design due to the large range for green indicator. It would be better if it were green down to 50%, then red from 49% down to 20% and red flashing below 20%. I usually just use the battery level indicator on my Garmin Edge. Once that gets below 50% (5 hours of use) I know it is time to charge the light. Another option is just to recharge the light after every use. With the Lithium Ion batteries, there is no concern about needing to discharge the battery completely before recharging like there used to be with Nickel Hydride batteries.

if i hang it upside down..then the anti-glare will be useless

RN600 is same product as Allty600? Why the lights are marked on the products with different names? Which name is newer?

Could be better if u included how long it takes to charge it with USB c so that we actually know how fast and how good is USB c feature

Can this light be charge while on the go?
