Right. It baffles me how Menards expects its customers to choose the correct adapter when no information is provided (that I can find) on the mA requirements for each building.
There are buildings with only 2 LEDs...and other buildings with more than 200 LEDs! At 10 mA per LED, that means one building might need 20 mA while a bigger building might require more than 2000 mA. And I have seen very little info on the mA requirements for the "neon" signs - some are somewhat complex and animated which one might reasonably assume would require more mA than a small basic sign.
This information would also be useful for guys wanting to power their buildings from transformer AC Accessory output (14-16V AC). There are a wide variety of converter options but you need to know the mA requirements for the building(s) to make an informed selection.
