A ballast resistor is necessary to run a bare laser tube. (Lasers that are in a metal head will have one built in.) It must be placed in series with the anode lead within 3" of the tube. Dale RS-10, 100K ohm, 10 Watt wire wound ballast resistor. Recommended for large HeNe laser tubes that operate up to 10mA. -
A Ballast resistor is necessary to run a bare laser tube. (Lasers that are in a metal head will have one built in.) It must be placed in series with the anode lead within 3" of the tube. 100K ohm, 2 Watt metal oxide ballast resistor. Recommended for HeNe laser tubes that operate on 4.5mA or less. -
