Query: Very dim bulb

I purchased this light bulb to place outside during Halloween. The bulb is very dim; hardly enough to light up 1 foot around the exterior lamp. It gives off a neat purple glow but is not effective. I believe the term "Black Light Blue" is misleading when the bulb that I received performed nothing AT ALL like the photo posted by 'Ruben R'.
