“Light units” is an iffy clue for “Watts”. Watts measure the energy used by a light bulb, not the amount of light produced.

Re: 55 down, “Metric wts.”, I do wish you’d stop conflating grams (or kilograms) with weight. Grams (and of course kilograms) measure mass, not weight. A better clue might be something like “Metric meas. of mass”.
