to attract flies. The center wavelength for most actinic light products is 420 nanometers, with longer wavelengths regarded as "royal blue" (450nm) to sky blue (470nm) and cyan (490nm) and shorter wavelengths regarded as "violet" (400nm) and blacklight (365nm). Actinic light centered at 420nm may

Actinic lighting is also a great alternative to black lights as it provides a "night environment" for the fish, while still allowing enough light for coral and other marine life to grow. Aesthetically, they make fluorescent coral "pop" to the eye, but in some cases also to promote the growth of

Actinic lighting is also used to limit algae growth in the aquarium. Since algae (like many other plants), flourish in shallower warm water, algae cannot effectively photosynthesize from blue and violet light, thus actinic light minimizes its photosynthetic benefit.

Actinic inspection of masks in computer chip manufacture refers to inspecting the mask with the same wavelength of light that the lithography system will use.
