The Norman Lamps F32T8-BL is a 32W T8 fluorescent blacklight tube engineered to emit ultraviolet UVA energy at a peak wavelength of 350nm. Measuring 48.0 inches in length and 1.00 inch in diameter, this 4-foot T8 fluorescent tube fits standard T8 fixtures equipped with a G13 medium bi-pin base. The lamp operates across a wide input voltage range of 120V to 277V, making it compatible with most commercial and residential fluorescent ballasts without the need for special wiring. Its frost-finished, uncoated glass envelope transmits UV energy while allowing some visible light output, classifying it as a Black Light White type as opposed to a Black Light Blue variant. This characteristic makes it well suited for use in insect control traps and bug zappers, where attracting insects through UV emission is the primary function. The 350nm peak emission falls within the UVA band, which is the range most effective for insect attraction and for causing fluorescent materials to glow. With an average rated life of 15,000 hours, the lamp provides extended service in continuous-duty applications. UV output in fluorescent blacklight lamps does diminish gradually over time, and annual replacement is recommended for insect trap installations to maintain effective performance. The F32T8-BL is also suitable for inspection tasks, fluorescent material detection, and other applications requiring a broad-spectrum UVA source. An LED alternative is available under order number LED-T818-405NBL for those seeking a non-fluorescent format.
