Here are the first few things that occur to me immediately
on which the answer to that question depends:
-- the chemical composition of the blue dye in the fabric
-- the color temperature of the flood lamp
-- the distance between the light source and the fabric
-- the shape and color of the fixture in which the lamp is mounted
-- the temperature of the air circulating past the fabric
-- the speed of the air circulating past the fabric
-- the composition of whatever the fabric is resting on
There are others.

Do flood lights use more energy?
No, flood lights do not use more energy. If the wattage is the same between a flood and a spot light, it is the wattage used that you pay for. It is the lens of the bulb that determines the light output pattern. A smooth surface will give a flood pattern where as a spot has a lens that focuses the light into a central location. A reflector flood has a silvered interior to direct the light outwards on to an object.
