There is so much more that you can do with indoor lighting than to see your way in the night. Depending on where you reside or what kind of animals you may have, it has many useful functions.
For those of you that have reptiles you know all too well how imperative the right indoor lighting is. Some reptiles, like a common snake, just need the basic lighting for a warm spot to coil up at night. If you are in a tight situation you may try a regular household bulb with minimal wattage. Now if you have a chameleon or some expensive gecko or dragon, then you will need to buy something more high-tech. While in captivity these pets need special UVB lighting in order to live like they do in the wild with the sun's rays. Depending on your lizard, your needs can differ. If you aren't sure what you require, you can just look it up online or check with your local vet that specializes in exotic pets. You need to understand that without the perfect lighting, your lizard that you spent all this money on will die from any number of degenerative diseases. Also in the reptile field are turtles. Every chance a turtle gets, they will be basking in the sun. In captivity they still need to bask and they must have a UVB light in stead of the sun's rays. Believe it or not, turtles are one of the most costly pets as far as their requirements are concerned.
On the other end of living things, there is a variety of house plants. There are many different requirements for your plants, depending on where you live. There areLED grow lightset ups if you live somewhere where it is dark much of the year. The variety of LED's is as diverse as plants. They start at an easy 28 watt LED grow light to a 225 LED grow light panel and anything in between. Or possibly you want to dedicate a complete room to your green babies and want the fullgrow room setup. It all depends on if this is a lifestyle or a simple hobby.
Those are two distinct kinds of indoor lighting. There are many more alternatives to try out in the indoor lighting arena. Basically there is no end to what a few extra watts can do to your place and your happiness. So remember, even if you live in Alaska, you can spend the day in 30 below temperature and come home to your indoor jungle, including snakes in the trees and ivy climbing the walls.
