Nilight 20-inch 420W LED Light Bar Triple-Row Flood + Spot Combo, 42,000LM IP67 Durable

Nilight’s 20-inch 420W LED light bar delivers a powerful triple-row flood-and-spot combo beam that lights wide and far for off-road, marine, and work applications.

This heavy-duty 20" light bar balances raw lumen output with durable construction so you get bright, consistent illumination without constant maintenance. Built with a triple-row LED array and a nested reflector cup in the center, the fixture produces a blend of near-field flood and long-throw spot light. The housing is die-cast aluminum with efficient cooling and an IP67 rating, and the kit includes a 12V wiring harness, 5-pin rocker switch, and connectors to simplify installation.
