hi there latly i have been playing with my dx 20 and i have noticed that when i run the laser off of a powersuply the beadm is very visible even in a well lit room, this visibility (well to that extent) dosnt happen even with fresh batteries .. this seems beculiar to me because same voltage (fresh batteries usualy have more than 1.5 volts) and im guessing the current load is quite small. any thoughts on why the laser is so powerfull with a powersuply?

Measure the current with the power supply and with batteries.That's most likely the cause of it.
