Cyberlight CL Bench Test

Need a little help,

I am bench testing 8 CL's to compare the light sources.

They are refurbished units and at the first show I could see a noticeable difference in output between some of them.

I want to repeat a point on the output chart that is found on the Data Sheet. Specifically the 15 foot reading of about 524 fc as that's my setup in the shop.

Given that the light output chart has a Beam Angle of 16 degrees listed on it, I am guessing that this means a fully zoomed in and focused beam setting? This is because one of the listed ranges is 16 - 26 degrees.

I guess the question is "what are all the beam parameters for this test?"

So far I have compared 3 units and one is visibly darker than the other 2 and optimizing the lamp does nothing. Literally, adjusting the lamp makes almost no noticible difference on the output. I pulled the lamp and it looks good and is an MSR 1200/2. Thinking it may be way out of position. Next check I think I'll pull one of the good ones and compare them physically. Or should I suspect the reflector?

Any Thoughts? :confused:

    Ok, so I tested all the fixtures yesterday. For each one they were set to the same parameters (IPCB) and I noted voltage and current at the fixture, along with the foot candles at 15 feet away at center beam and "optimized" the lamp. Got some interesting results.

    Voltage was always 209VAC, taps are set for 208V 60Hz.

    Fixture, current, ftcd
    1, 8.5A, 150 ftcd
    2, 3.9A, 530 ftcd
    3, 8.6A, 140 ftcd
    4, 8.8A, 850 ftcd
    5, 8.5A, 750 ftcd
    6, 3.8A, 150 ftcd
    7, Lamp strikes for a few minutes then shuts off
    8, no lamp, stole it for one of the others


    Best guess is it's a wide range of lamp life's. Think we'll buy some new lamps and see what results we get.
