laser HEADS: are laser tubes enclosed in an aluminum housing with an internal
ballast resistor and an ALDEN high voltage connector
laser TUBES: do not include the housing but I will include a ballast resistor
and clips to which you can solder the high voltage leads
Note: the power output of each tube was measured using a Newport power meter
cal'd to 632.8nm with the test aperature fully illuminated. The first reading
is the initial power output and the second reading is the power output after
a 20 minute warm up.
