Replacement light bulb for DT2000XL.
ULTRAVIOLET LIGHT RAYS
Mosquitos and other flying insects react extremely sensitively to certain wavelength of ultraviolet rays. The Dynatrap's special UV bulbs are made of the highest quality and designed to last approximately 3000 hours (or 4 months). The Dynatrap can attract and capture mosquitos both in bright and dark outdoors and indoors, and is designed to run 24/7.
TITANIUM DIOXIDE COATING
Mosquitos, even in the dark, can easily find where people or animals are by sensing their carbon dioxide and temperature emanations. Scientists consider carbon dioxide as the single most important cue used by mosquitos for locating a source of blood. Certain parts inside the Dynatrap are coated with titanium dioxide (TiO2), and when the Dynatrap's special ultraviolet wavelength hits the TiO2, a photocatalytic reaction takes place that produces carbon dioxide. This is the same CO2 that humans exhale, and is irresistible to mosquitos.
POWERFUL VACUUM ACTION FAN
Once flying insects have been attracted to the Dynatrap by warm UV light and CO2, the Dynatrap's powerful (yet whisper-quiet) fan serves two functions. It is first used to draw insects into the retaining cage. It then keeps those insects from escaping using the vacuum action created by the continuous cycle of the fan. The Dynatrap is energy efficient and is designed to run continuously. The fan is so quiet, it's hardly noticeable.
Insects are drawn into the retaining cage trapping them until they dehydrate and die. The retaining cage can be removed, allowing the contents to be periodically emptied into the trash. The screened material on the retaining cage allows what has been trapped in the unit to be seen, and alerting you when the cage needs to be emptied. A special interchangeable retaining net can also be purchased for use with some Dynatrap models for high catch rates — typically useful in agricultural settings near livestock.
