Traditional LED drivers (like a ballast inside of a legacy fluorescent light fixture) are life-limited components and have a MBTF of around 50,000 hours, well short of the LED lifespan of around 200,000 hours. We realized early on this was not acceptable in a tunnel environment, where maintenance is difficult and expensive.
Instead, we’ve built our tunnel lighting fixtures around modern direct-AC technology. This method is 100% solid-state, driving the LEDs directly from the AC input and eliminating the traditional LED driver, enabling us to provide an industry-leading 10 year warranty. Our proprietary direct-AC implementation is EMI silent, easily passing the most stringent MIL-STD-461 RF emissions testing.
An additional benefit of the direct-AC technology is its compact size. This compounds the already minimal space requirements of LED technology, resulting in an incredibly small form factor of just 1” round. This provides engineers the freedom to place the lighting fixtures where space is available, while keeping the fixture out of the train’s dynamic envelope.
An all-in-one lighting solution, our rail tunnel fixture features bi-level lighting, providing both normal and maintenance lighting from a single fixture. This feature eliminates the need to hang temporary lighting during maintenance events, saving time and money.
