Ok now that I am complete my testing for this balast and lights here are the results. First to mention the equipment I am using again 1, GE Electronic
B340R120HP PC#80156 3 lamp rapid start ballast and 1 philips 03/actinic 36" bulb.
to record this info I am using a new radioshack digital auto range multimeter, and a GE light meter.
first, the test setup looks like this
I took initial reading and then again took readings after 25 minuits of the set up running and having a chance to settle out.
here is the first test runing the bulb at normal power.
the inital current was 0.330 amps (39.6 watts)and it climbed to 0.332, (39.84 watts)not a significant change so I only recorded the start curent, the ballast was cold after this test and the bulb was warm.
the light output remained constant at 13 foot candles @ 12" and 190 foot candles at the bulb surface
for the second set I used 2 sets of leads to the power side of the bulb.
the inital current was 0.460 amps (55.2 watts) and the final curent droped to 0.455 amps (54.6 watts), the balast was 84 degrees F and the bulb was warm (about the same as test 1).
the light output remained constant at 19 foot candles @ 12" and 320 foot candles at the bulb surface
