Not all tunnel lighting architectures are built the same. The differences will matter over 25 years.

"Driverless" LED tunnel lighting is generating real interest among procurement teams. Before it appears in your next RFP, it helps to understand what the term actually means and what it does not.

This whitepaper breaks down how LED power supply design affects reliability, maintenance costs, and compliance over a fixture's full lifecycle. No power electronics background required.

Inside this whitepaper:

• How the two dominant tunnel lighting architectures differ in real-world performance and field serviceability

• What heat buildup does to fixture lifespan underground, and why tunnel environments amplify the risk

• How to think about surge protection, EMI compliance, and Buy America requirements when evaluating competing products

• Eight plain-language questions to include in your next RFP
