10kV vs 20kV Surge Protection Compared

10kV vs 20kV Surge Protection Compared

Surge protection guards LED drivers from voltage spikes and lightning. 10kV is the standard baseline for most sports fixtures; 20kV is recommended for tall poles, open fields, and lightning-prone regions where exposure is higher. Upgrading to 20kV is inexpensive insurance against costly driver failures.

This comparison helps you choose the surge rating.

How to choose

Choose 10kV for low-exposure, budget-sensitive sites with typical conditions. Choose 20kV for tall, exposed, or lightning-prone locations, where poles act like antennas for lightning-induced transients and grid surges. The economics favor the upgrade where risk is real: 20kV adds a small amount to the fixture cost, far less than the cost of replacing a failed driver (parts, a crane, and labor at height) plus the downtime of a field that goes dark before an event. Surge protection is one pillar of reliability alongside quality drivers and thermal design. Duvon offers high-surge (20kV) configurations.

Frequently asked questions

What's the difference between 10kV and 20kV surge protection?

Both guard drivers from spikes and lightning; 10kV is the standard baseline, 20kV is for tall, exposed, or lightning-prone sites.

When is 10kV enough?

For low-exposure, budget-sensitive sites with typical conditions.

When should I choose 20kV?

For tall masts, open or exposed fields, and high-lightning regions.

Is 20kV worth the extra cost?

Yes for exposed sites — it's small relative to replacing failed drivers and the downtime of a dark field.

Does a nearby strike matter if it's not a direct hit?

Yes — even a nearby strike induces a damaging surge, which is why exposed sites benefit from higher protection.
