I know actinic is usually referred to as blue lighting. But what is it really? Are ati blue plus considered actinic? Are blue leds like blue reefbrites considered actinic?
Just to throw in useless information actinic light used to mean light that would expose photographic (B&W) film - ie the green or blue parts of the spectrum. A non-actinic light was a safe light - ie a red light in a darkroom.
But now as tkeracer619 says, it customarily refers to light that peaks at 420 nm - violet. Blue is defined as peaking at 470 nm.
The ATI Blue+ is advertised as having a combination of 460 and 420. The ATI True Actinic is spec'd as peaking at 421 nm.
