Thanks Igor, no I won't use different types of batteries. Until I get my rechargeables, I have 3X3 volt cr123 in series with 2 1N4001 in series from the positive terminal of the batteries. That is dropping the voltage from ~9 volts to ~7.6 volts and 450ma. These are almost fresh batteries, but not brand new. I don't know how much voltage from the input is unwise for the LD, but I know that the regulator will heat up if it receives too much input voltage with the red diodes. Thanks for all of your help.
