I've 4 years of degree building lighting lecture notes and several years of amateur theatrical, band and disco lighting work too and I had to check the units to make sure I got them right. I was surprised that I had remember lumens and lux the right way round when I was looking :-)
Unfortunately the correct units are rarely used for the the public. Watts/Second for a strobe is another case of that in the same way as light bulbs only having wattage on - it didn't matter when they were all of the same type but now we use so many types it's time they actually gave us a bit more information on the boxes rather than the silly 20W bulb equivalent to an incandescent 100W bulb.
