Wattage, Voltage and Resistance: Reading LED Work Light Specs Correctly

A specifications table condenses design decisions into a few lines. The three numbers that matter are power (W), driving voltage range and LED configuration.

Power states total draw, letting you check the light against your electrical system and fuse rating before installation.

Voltage tolerance such as 9–36V means the unit regulates brightness across the wild dips and spikes of a vehicle system without damage or flicker.

LED count and layout hint at beam shape and density. Compare models with identical numbers to choose between a broad even wash and a denser, more focused field.
