Black light (ultra violet) collecting lights attract many night flying insects, providing maximum insect response from the UV spectrum. This compact 20 watt, 110 volt, AC current, self-ballasted fluorescent black light bulb can be used in any standard/medium base lamp socket. The small size makes it ideal for travel, for use with a variety of insect traps, or when using a collecting sheet. Perhaps you can put it into your porch light fixture and see what unusual insects arrive. The bulb emits 350 nanometers of UV light, the same as our #2807A 15 watt BL bulb, a frequency which attracts many insects. Caution should be taken when operating the bulb in wet or rainy conditions. Size: 1-3/4” (4.45 cm) in diameter and 6-1/2” (16.51 cm) long. Weight is 3 oz., (85 grams).
