so how do night breakers produce 110% more light but still remain legal?

110% is commercial.. you will see a good increase, but not as this high I think.

But legality is not only a question of light output. It's also a beam pattern question, headlight reflector are made with a precise position and form of filament.
So bulbs have to be precisely made, with respect of power and pattern.

Update ! Interesting things found :

And what is really strange is all the bulbs have the same output power in lumens !!!
The two things that change is color temperature and lifespan...
No chance, whiter (3900-4100 °k) bulbs have the lowest life. Not the new of the year, but you can put numbers... (and for some they are REALLY low)

Another test, Philips this time :

From the longlife to the brightest.. 1650lm ! Something is wrong... or we are just stupid consumers .
