LED floodlights will not work well. They will still work... but painfully slow maybe 30 minutes exposure, or something crazy like that.
This is because they emit very little UV light.

For regular emulsion, the common 395nm UV lights will be good enough.
The indicated 395nm is just the peak. They actually emit plenty of 375 to 405nm wavelength.
More watts = more light = faster exposure.
It has to be actual consumption watts though, and not "equivalent".
