I presume the source aims to simulate the conditions that may trigger photo-triggered epilepsy.
In that case, brightness measured in Lux would be appropriate, plus, if the source flashes, you could measure on-off times, and possibly risetime (time for 10-90% max is the standard descriptor). These last two could be measured using a simple photodiode and a 20Mhz oscilloscope.
Or you could ask the manufacturers for more information...

Dear List
We have been asked to measure the light output of a new broadband light source that will be used in the diagnosis of paediatric patients who may have Epilepsy. This is something that we have not attempted before at this centre.
I would be interested to hear if anyone else has done this before and if so what detector did they use. Would they also be willing to share their protocol either on or off list.
Regards
