The power meter was saying around 40W which is implausibly low and was
varying +/- about 30% between runs, either we weren't using it right, or
it's hugely out of calibration.
It's back in the dropbox any time you want to pick it up Tom
Overall the tube is starting to show it's age, with the amount of use
we've given it recently, we'll probably be looking at a new tube some
time around the end of the year based on the current usage rate.
