Babies undergoing phototherapy for hyperbilirubinemia, have eye masks to prevent risk of UV exposure and to eliminate risk of retinopathy of prematurity. Lights in neonatal wards are not allowed on 24 hours a day. Direct & bare lamp use is not allowed.

Phototherapy lamps used have a special phosphor coatings only for bililights. As an added precaution the bililights I designed use a museum quality acrylic UV filter.

Newer medical research indicates a slight shift in action spectrum may speed photo therapy. LEDs can be used for this phototherapy. Much research has found them to be as effective as the special fluorescent bililamps, however as LEDs have a more pronounced spectral peak, it may be possible that superior combination of LEDs and phosphors may replicate a faster reacting action spectrum.

LEDs can offer similar, if not the same phototherapy as the best fluorescent bililamps, but as all lights dim in brightness as they age, control algorithms for LEDs can ensure maintained light levels are delivered for a 15 year bililight source service lives. This is not yet being done for phototherapy but I trust testing may soon start.
