i like the fact that i can also run on AAA 's but does your personal light settings work when the AAA batteries are used instead of the rechargeable core?
The power source shouldn't make any difference with the settings.
John - which personal light settings are you refer to? You'll always be able to control the maximum, economic and strobe setting through the use of the button/on/off switch, regardless of battery. However, the rechargeable battery is what you program to either an even drain across the life or brighter at first and then dimmer (like using AAAs). If you remove the rechargeable battery, then the settings will no longer be in effect.
