3×
faster bilirubin decline (0.40 vs. 0.14 mg/dL/h) in a 2026 randomized home-phototherapy trial.
15.1 h
mean treatment time, vs. 25.1 h with unidirectional phototherapy from below.
Thermally supportive
A semi-enclosed, reflective design keeps a stable warm microenvironment, with automatic over-temperature shutoff.
