Simplicity itself, this black light bulb sits neatly into pretty much any bayonet style light fitting in lamps or light fixtures and gives off a constant stream of UV light, which is perfect for super-charging glow in the dark products and highlighting anything with fluorescent colours.
This bulb is actually a fluorescent tube formed into the shape of a light bulb, much like modern 'Energy Saving' light bulbs. In fact, the black light bulb only uses 11 watts itself and will last for years and years.
Ideal for people wanting to play with black light without having to change batteries or mount any new light-fixtures to the wall. Just replace a standard light bulb with this one and enjoy hours of UV fun.

They don't put out huge amounts of UV light (compared to a 4ft tube for example, understandably), so you would need a few to UV light an average room effectively. Their plus side is they're very convenient and easy to store unlike bigger UV sources.

Not enough power for a kitchen to serve drinks for a party, as was my intention. Seems you need at least double the wattage for that. Great as a hall light for Halloween or the like

These are fantastic! Great value for money and an instant fun party effect with no hassle (simply put them in your regular light fitting) One of ours stopped working after a few days but after a quick phone call to your customer services and a replacement was quickly despatched to arrive the following day. Excellent service and a great product.
