All reptiles must have distinct day and night periods in their enclosure to maintain their biological rhythms. Veiled chameleons need 8-12 hours of daytime and 8-12 hours of nighttime. However, as the daylight hours change seasonally outside, daylight hours inside the tank should reflect the same.
As providing the lights for my Veiled cham, does a chameleon need ..
If you think you can't survive without electricity, imagine what it is like to be physically dependent on the light bulbs hanging from your ceiling. This is the reality for our cold blooded pets. From calcium absorption to thermoregulation, the functions of a reptile's body require a spectrum of lighting to work. An in-depth understanding of lights is essential to the success and well being of your Veiled Chameleon. So, what exactly is the difference between a regular light bulb and a bulb created specifically for our scaly friends?
Lighting for Veiled Chameleons - Reptile & Parrots Forum
Ultraviolet-B (UVB) is present in sunlight from the wavelengths of 290(nm) to 315(nm), and almost all animals on earth have some level of exposure to it. Reptiles have a particular need for UVB, as the Vitamin D they absorb from the sun is converted into D3, which plays a crucial role in their bodies. In deficit of D3, calcium cannot be utilized in their systems. This causes the bones of your Veiled Chameleon to slowly deteriorate, becoming brittle and malformed. The painful and fatal condition is referred to as Metabolic Bone Disease(MBD). Though it is one of the leading killers in the reptile industry, MBD can easily be avoided.

The Veiled Chameleon (Chamaeleo calyptratus), also known as the Yemen Chameleon, is a relatively large chameleon species originally from Saudi Arabia and Yemen in the Middle East. More recently, this species has been introduced and has established small populations in areas such as the island of Maui in Hawaii. In its natural range, the Veiled Chameleon lives in coastal mountain slopes, which experience significant rainfall, and some live in slightly more arid “wadis” with year-round water and vegetation. Veiled chameleons sleep at night and should have the lights out. During the day, bright lights should be placed on top of the enclosure to allow the chameleon to climb upward to find heat. During the day, the gradient of heat in the cage should be 80_F to 95_F, while at night 70_F to 85_F. The chameleon will seek its own level of comfort by choosing its height within the cage. Heat emmitters which do not produce light are readily available from pet stores for night time use. Because chameleons' primary heat sensors are on their backs, chameleons should not be given "heat rocks" or under substrate heating pads; the use of these items could result in your chameleon being badly burned.
