I recommend using the TS10 at indoor distances and brightness.. Turbo is a waste of batteries, constricts pupils, causes rapid step down in output, to a dimmer level than if the light was not heated by Turbo first.
Stock Advanced Ceiling of 120/150 (on Aluminum models) gives about 400 lumens, I suggest using less than that.. I disable Turbo, and lower the ceiling in simple mode to 120/150... (someone made a mistake and set the ceiling to equal Turbo in Simple mode)
On the Titanium TS10, someone made a mistake and set the Advanced ceiling to equal Turbo. I change that to level 120/150 also.
enjoy your little close range light.. dont use Turbo. Dont chase the dragon, dont use 10A batteries..
