If you want to get the most out of halloween, ultraviolet effects are becoming all the buzz for creating that signature eerie glow. With a little help from these three UV replacement bulbs, your parties and events will be remembered with the spooky lighting effect: making whites and lighter colours; costumes and decorations bounce out from the darkness. Effortlessly secured into ordinary light fittings, the Beamz UV bulbs dont miss a trick (or treat): with the option of connecting to either edison screw-on fittings bayonet slot-in fittings using the adaptor supplied.
