LED Module replacement
Failure of individual LEDs does not necessarily require module replacement. Measurements utilizing lux
calibrating cameras have shown that multiple single LEDs can fail within one or more modules with no
noticeable effect on the light field.
E 778 - Up to 5 single LEDs may fail; either 5 in one module or one in 5 different modules (or any
combination) per the truth table below. When the 6th single LED fails, modules must be replaced until the
truth table is satisfied.
E558/E668 - Up to 2 single LEDs may fail; either 2 in one module or 1 in 2 different modules. When the 3rd
single LED fails, modules must be replaced to satisfy the truth table (below).
GREEN Light field not affected. No module replacement required.
YELLOW Light field minimally affected. Module replacement required.
RED Light field adversely affected. Module replacement required.
CAUTION: If the LED Modules are replaced incorrectly by an unqualified
technician, significant damage may result to the Light Head.
