For optimal use, operate at 77°F (25°C) at a maximum distance of 0.5 inch (1.3cm) with fresh batteries (less than 3 hours of use).

* Tests conducted and verified under Anastasia Gregoriades, Ph.D., at Queens College (New York) established the kill ratio by the DeGERM-inator™ on the organisms cited.

• The lethal exposure time of the organism is determined by the wavelength of radiation, density of radiant flux (µW/cm²) and time.
• The time required to kill or inactivate greater than 90% is proportionate to the ratio of the required killing energy and the irradiance of the light source, i.e., Time = Energy Required (µW.sec/cm²)/ Irradiance (µW/cm²).
• The ultraviolet output can vary considerably with temperature, distance and battery charge.
• Safe exposure limits for ultraviolet germicidal radiation have been set by the American Conference of Governmental and Industrial Hygienists, as noted below.
