The GE 1-Light Black Fluorescent Light is perfect for dorm rooms, posters and Halloween parties. This light uses a 15-watt fluorescent bulb (included) and is easy to install. It is a plug-in fixture so there's no wiring required.
This blacklight was better than a number of others that I looked at, and was less expensive as well. While not especially large, it works great for a small to medium-sized bedroom, and made all my posters that seemed lackluster with my previous incandescent blacklight look fantastic. The bulb itself is mounted behind an acrylic housing, so it's not easily broken. A much-needed feature not found on the other lights.
