Phototherapy is effectively used for treating neonatal unconjugated hyperbilirubinemia: The BiliLux phototherapy light has its irradiance peaks in the most effective wavelength range to reduce the bilirubin which is 460 – 490nm. By achieving extremely high irradiance levels, the BiliLux fullfills the requirements of the American Academy of Pediatrics (AAP). In addition, the irradiance can be dimmed in 5 steps to provide proper therapy for the individual patient. The phototherapy light features a large surface area to cover full term and premature babies. The irradiance is evenly distributed over the entire mattress to help ensure effective phototherapy.
