LED lamps generally have a different spectral power distribution than conventional lamps, with more opportunity to add or subtract specific ranges of wavelengths, such as infrared (IR), ultraviolet (UV), or specific wavelength regions within the visible spectrum. This is an important attribute to consider when lighting sensitive objects, such as artwork. Similarly, limiting infrared (heat) in the radiated beam can be especially important when illuminating heat­sensitive objects, such as food (e.g., chocolate). White LEDs emit very little infrared radiation. In contrast, halogen lamps emit approximately 85% of the total input power as infrared radiation.
