Keep the advertising bullshit separate from the reality!
Led bulbs make more light for the same Watts...or you could say same the same light for less watts...Fluorescent bulbs also make more light for a given wattage...
But Led light is still weird to me...funny color of the light, and it does not project evenly....although they are getting better.
But 90 additional watts added to a small electrical system..I'd worry a bit....LED or filament bulb...90 watts is 90 watts...strain on the system.

Watt you say? Well said. If you buy LEDs for your house they say the actual wattage and the "equivalent". So a 10 watt draw puts out as much light as a 60 watt incandescent. Lumens are a bright way of rating them.
