LED count and wattage on red light panels

A panel with more LEDs or a larger electrical wattage can look stronger on a spec sheet. Those numbers do not tell you how much useful light reaches the treatment area at the distance you actually use.

LED count helps explain design

LED count can tell you something about panel construction and potential coverage. It does not reveal wavelength accuracy, optical design, drive level, uniformity, or delivered irradiance.

Electrical wattage is an input

Power consumption describes electricity used by the device. Optical output depends on the LEDs, drivers, lenses, heat management, and other design choices.

Ask for output with context

Look for irradiance at a stated distance and, when available, information about measurement equipment and coverage uniformity. Those details make output claims easier to interpret.
