Interior LED Lightbulb Spectrum Comparison

A multi-spectral digital sensor is used to compare the spectral power distribution of two A15 800 lumen (60-watt equivalent) interior light bulbs.

The Osram is a conventional 2700K soft white bulb with a light output measurably weighted above 550nm, and objects reflecting this light are noticeably warm in tone.

The GE Refresh bulb fits in the category of daylight and provides greater luminance in the shorter wavelengths or cooler colors.

Output levels are relative to a full-spectrum white sensor on the same device just at the saturation level of 65000.
