+25% -20% (after a 5 minute warm-up time, and 38 cm
from the light shade to the center of the spot with a new system and new
LED, measured by a calibrated Biliblanket Light Meter II).
Life Span
The product is designed to meet a life span of 7 years. However, with
proper maintenance and repairs, the service life can be extended as long as
service parts are available.
* IEC standards recommend LED replacement at 25% output reduction, which occurs at approximately 10000 hours. However,
sucient irradiance for eective phototherapy continues well after 25% reduction.
