I expect this correction will only make break-even times slightly
shorter if electricity consumption during the life of the lamp (bulb)
costs a lot more than the lamp (bulb) does, which is often the case.
With lower wattage lamps, lamp cost becomes a more significant fraction
of the total cost, so this correction gets less minor.

I would think it would make quite a big difference, but havent calced
it yet.
