Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. ... It is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay.
Ranges from 18W, 26W, 35W, 55W, 66W, 90W, 91W, 135W etc and the LAX series of electronic ballasts for Low Pressure Sodium lamp developed by leianxun company adopt the SCM CPU digital technique. It insures the intellectual protection of electronic ballasts---keeping the safety of ballasts and the system , when the voltage output terminal is abnormal. In the process of warm-up, triggering, and ignition, the CPU can reach the best state to protect the electrode of lamp /tubes. This is measured by the microsecond controlling span of system and the height of impulse from the trigger voltage. Thus it doubles the longevity of the electrode for lamp tubes greatly.
It is perfect for solar power of street lighting.
