Untreated gonorrhea can cause serious and permanent health problems in both women and men. In women, gonorrhea can spread into the uterus or fallopian tubes and cause pelvic inflammatory disease (PID). The symptoms may be quite mild or can be very severe and can include abdominal pain and fever .
The lumen (lm) is an international standardized measurement unit that tells you how much total light is emitted by an LED or other kind of light source. In more technical terms, it is a measure of luminous flux.
The combination of lumen-maintenance life (Lp) with statistically-measured failures (Bp) is the LED light sourceâs rated life, or BpLp value. For example, if an LED light source is claimed to have B50L70 of 30,000 hours, then 50% of tested samples should have a lumen-maintenance life of 30,000 hours. Ideally, to obtain the rated life for LEDs, the statistical failure measurement can be integrated with lumen-maintenance measurements during the life test.
