WebFeb 4, 2024 · You can expect to spend about $4 for an affordable 36-inch fluorescent tube light bulb or close to $10-$20 for an adjustable light from a hardware store. There are quite a few options to buy full-spectrum light bulbs online, with many ranging around $20 for a single full-spectrum bulb. WebUltraviolet light encompasses a wide range of wavelengths, but most blacklight applications utilize a narrow range of ultraviolet radiation (UV-A) to produce fluorescence effects - specifically between 350 and 400 nm (nanometers). But even within the 350-400 nm range, different wavelengths can create stronger or weaker fluorescence effects.
Fluorescent lamp tubes are often straight and range in length from about 100 millimeters (3.9 in) for miniature lamps, to 2.43 meters (8.0 ft) for high-output lamps. Some lamps have the tube bent into a circle, used for table lamps or other places where a more compact light source is desired.
