Back about monitors and light intensities.
He explained that basically the suns light intensity at noon time where monitors are found is about 25 times what the brightest office lighting is (equivalent to or half the intensity of the same light intensity readings found in early evening after the sun has gone down and most monitors are sleeping, even in the open in nature), the average house lightbulbs (most commonly used by most reptile keepers with reptiles in captivity) are around 1/4th to 1/10th the intensity of such office lighting (equivalent to or less than the intensity readings measured outdoors in areas monitors live naturally hours after they have gone to sleep and the sun is down). The light intensity readings from those mercury vapor bulbs can produce light intensities around 2-2.5 times that of the brightest office lighting.
So considering this, how could we ever bother, let alone effect a light cycle on anything with household lighting, its not possible, I think its an illusion or an excuse, also it helps the pet industry sell a fortune in reptile lightbulbs.
Ill see if I can find the quote from Sam, I know I saved that one, it seemed so useful for future discussions on monitors, reptiles, and light cycles, also debunks alot of myths on forcing light cycles, or what monitors think of our lightbulbs, or how they compare to the sun in any way.
