Blacklight blue produces the popular special effect light that you see at arcades and discos. It makes things with phosphorescent reactive properties glow, white teeth for example. These lights are often referred to as hippy lights because of their surge in popularity in the 60s. They employ “Wood's Glass” which is nickel-oxide-doped glass. Or in layman terms; an exterior coating that blocks most visible light and allows ultraviolet through.
Black Light bulbs are typically used for bug zappers. They do not use “Wood's Glass”, they employ a U.V. transmissive glass. When not alight they appear white, when on they appear electric blue. They attract and dispose of flies keeping your eating space or kitchen bug free.
