Was it brighter than on dynamo when it got to 800mA or so?
I couldn't do a realistic comparison of dynamo mode & DC 800mA since one involves riding around and the other case was
with the light hooked up to a mains power supply shining against a wall.
I tried with a battery slightly above 6V last night. This gave ~300mA and I thought it seemed slightly brighter in dynamo mode
but couldn't swear to it, since there was 5 minutes of fiddling to switch between modes.
When running in boosted mode I will be cautious about taking it much over 0.5A especially if it doesn't give much
extra light for the battery drain. The LEDs should have reasonable cooling since they are in contact with the metal case.
