THE SGP LAMP SERIAL NUMBER IS ORL 787 AND IT CALLS FOR POWER TAP #3  191.5 WATTS

John


All ARM LI-COR lamps operate on power tap #3 at 191.5 watts.
This can be tested by multiplying measured lamp voltage by measured lamp current;
lamp current is really a voltage that has to be divided by 10 to get amps. Should 
be 191.5 to within 0.1%

I tested 1204, which was still in the calibrator when it was shipped.
I found it to be too low by about 3-4% depending on wavelength. I then 
noticed that it was mounted backwards from the way the manual states it
should be so I turned it around and measured within about 1% of my NIST
compared lamps -- this underscores importance of getting lamp mounted
correctly and also says that LI-COR does a pretty good job of calibrating
to NIST standards.
