I’m looking for floodlights, for base lighting, but I can’t find any…not sure where to look, but they just don’t seem to be around. Any suggestions?
Most firetrucks has floodlights installed 
They can also be at some garage and house basements.
Some firetrucks, deluxe RV’s. I think they are craftable as well.
Floodlights draw a huge amount of power. Aisle lights or headlights have nearly as much useful light for much less power.
