Lights with lower colour temperatures are less disruptive to wildlife because they produce light that is closer in colour to natural moonlight and starlight. This can help minimize the impact of artificial light on nocturnal animals and allow them to carry out their natural behaviours without interference.
Red LED lighting is ideal for animal research laboratories. This new spectrum of light, 630nm, maintains sleep cycles for nocturnal animals such as mice and rats. Research facilities commonly use rodents for study, and therefore must address the issue of proper lighting for these nocturnal animals.
If you're worried about LEdDs harming your pets, don't be. There is no difference in safety between LED lights and other light bulbs on the market. In fact, if you were to compare the two types of bulbs together, you'd find that LEDs are actually better for your pets than any other light on the market.
The team of biologists surveyed select species around the world to determine how the hues of modern light-emitting diode (LED) lamps affect wildlife. They found that blues and whites are worst while yellow, amber and green are more benign. Some creatures, including sea turtles and insects, are especially vulnerable.
LED night light bulbs are very energy-efficient night lights on the market and it's not very expensive. You can leave it continually running and they are really worth the cash.
Blue light, the type that comes from electronic devices, has shorter wavelengths (450 and 495 nm). Blue light has been implicated in keeping us awake at night—that's why experts recommend turning off your devices well before bedtime. But red light may have the opposite effect and aid in creating drowsiness.
Research studies discovered red to be the best color light to help you sleep, because it increases production of melatonin as well as full darkness. On the other end of the spectrum, blue is the worst. Despite being a calm-inducing color on most occasions, blue is not suitable for lighting a bedroom.
Perhaps the biggest drawback of LED light bulbs is that they emit more blue light than incandescent bulbs, which are more on the red end of the spectrum. Blue light can cause a disruption in your circadian rhythm, negatively affect your ability to fall asleep and the quality of your sleep.
Nocturnal hunters, such as those from the cat family, sharks, and crocodiles, have a layer of cells in their eyes called a tapetum lucidum, which reflects light. This greatly increases sensitivity in dim light or darkness so that animals can see more.
Artificial lights alter an animal's circadian rhythm and create miss-cues. Lights can draw & disorient (hatchling turtles, night flying moths, frogs & amphibians, birds) or repel from the area thus forming barrier leading to habitat loss (rodents, many bats), especially site specific ones.
A better choice would be fluorescent or even LED lighting solutions. These two options will give you better lumen output with lower watts and create a clean, crisp illumination to highlight the animals nicely.
Commons reasons to use a pet light include keeping the animal calm, giving them a sense of company, or helping them to see. Some dog owners say that their pets are afraid of the dark. This will only apply to a small number of dogs, but there is an easy way to tell if your dog is afraid of the dark.
Using Amber or Red Lights
These types of lamps will not disturb nocturnal animals.
Not only do LED lights make your garden look attractive at night, but they're also used by some homeowners to deter possums from entering their yard. Switch on a few fixtures in strategic places in your garden and you won't be seeing possums anywhere near them.
Nocturnal animals have more rod cells in their eyes as compared to humans and other animals active during the day. These rod cells serve as light receptors and help them see in dim light.
The biggest advatage of red light is that it does not spook animals as much as white light, they find it considerably less alarming and in some cases barely notice the red light. This means you can get closer to them and observe them better.
Human vision is restricted to a small portion of the electromagnetic spectrum; there are many kinds of electromagnetic waves that we cannot see. Nocturnal animals, on the other hand, have access to the wider sections of the spectrum and can see the infrared or ultraviolet spectrum as well.
Violence & Scariness
Lots, and sometimes it's very intense. Groping and sexual assault, harassment on the road (including a car trying to force another off the road), abduction, rape (viewers don't see it, but it's clear what's about to happen), and murder.
Colour vision is much more reliable than achromatic contrast, not only under changing light intensities, but also under the colour changes occurring during dusk and dawn. It can be expected that nocturnal animals other than moths and geckos make use of the highly reliable colour signals in dim light.
The light-emitting diode (LED) is today's most energy-efficient and rapidly-developing lighting technology. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.
LED lights outperform other forms of lighting in every area. They are more efficient in their use of electricity. They are cooler, don't waste energy as heat, and therefore safer. Thirdly, they last far longer than the alternatives.
The worst colors for bedroom lighting are blue and white light. Most of us are no strangers to the dangers of blue light from screen-based electronics. It is well known that exposure to blue light can negatively affect sleep quality. Babies and children are also negatively affected by blue and white light before bed.
Exposure to white light during the day can have positive effects, including boosting alertness and mood. Red light has no effect on the circadian clock, so you can use a dim red light at night. Yellow and orange light have little effect on the clock so you can use a very dim yellow or orange light at night.
