They don't.

The old dynamo powered standard incandescent rear light bulb was 6V-0.1A or 0.6 watts.
New red rear LED light bulbs are 1 watt or low power white light bulbs are 0.5 watts.
So no real power saving.
What they do is throw out a lot more light for the same power used as less power is lost to heat.

Luck ........ :D

I suggest you try it.
Modern led lights use less power for more light output.
Shimano now do 1.5w hub dynamos to power led lights so your 3w dynamo will easily power more rear led lights.
