Phototherapy exposes a jaundiced baby’s skin to a bright 

blue LED (Light Emitting Diode) light. The light converts 

bilirubin in the blood into a form that can naturally pass 

through the body. Nearly all babies with jaundice can be 

treated with phototherapy.

1.2.4 What is Phototherapy?

1.2.5 What is the 

bili-hut™

?

The 

bili-hut™

 is a portable device that uses a curved blue 

LED light array. It is specially designed to deliver high- 

intensity phototherapy treatment to more quickly decrease 

the amount of bilirubin in a baby’s body. The 

bili-hut™

 is 

easy to use, clean, and transport.
The 

bili-hut™

 allows for safe and effective treatment in 

either the clinical environment or home when used as 

instructed.
