I'm not quite sure what type of light you bought for your bird, but there is absolutely no reason nor requirement to buy an artificial light for a pet parrot...none. This is a subject that has been of much discussion forever, and there is never a good answer given as to why artificial lights are not needed or are needed for a pet bird...Well, the short-answer is that birds, much like humans, get what they need from their nutrition, not from the light, nor do they need an artificial light in order to process their nutrition like reptiles and amphibians do, for instance.
Just as humans can get sick from a lack of Vitamin D (the main vitamin we get from natural sunlight), we don't come down with this disease often, nor do birds...why? Because we/they get all the Vitamin D, as well as other natural sunlight benefits, from our fortified diets.
Reptile and Amphibians have all of those special light bulbs and strips commercially available BECAUSE THEIR BODIES CANNOT PROCESS THE NUTRITION THEY TAKE-IN FROM THEIR FOOD WITHOUT DIRECT UVB LIGHT, EITHER FROM NATURAL SUNLIGHT OR, IF LIVING AS A PET INSIDE, FROM AN ARTIFICIAL LIGHT!!! UVB light actually causes most Reptiles and Amphibians bodies to manufacture their own Vitamin D3, and without direct UVB light they cannot manufacture Vitamin D3 (also the reason why most Reptile and Amphibian multi-vitamin supplements and Calcium supplements contain a high content of Vitamin D3)...Vitamin D3 allows the bodies of Reptiles and Amphibians to be able to both process and absorb Calcium. Without direct Vitamin D3 from light, Reptiles and Amphibians simply excrete any and all Calcium they ingest from their food and from supplements out in their feces. So as a result, their bodies start to leech all of the Calcium from their bones, causing Metabolic Bone Disease (MBD). Therefore, it's essential that most Reptiles and Amphibians either get 1-2 hours of natural sunlight every single day, or 12-13 hours of artificial UVB light every single day...As a side note, the other slew of commercially-sold light bulbs for Reptiles and Amphibians that are not UVB bulbs, but rather "UV" bulbs or "UVA" bulbs are simply for heat. UVA light is the only light spectrum that can penetrate glass or clean plastic (UVB light can NEVER penetrate glass or clear plastic, so Reptiles, birds, humans, etc. NEVER get ANY UVB light through windows!)...So as we see and feel the natural sunlight coming through the window, we are only feeling/seeing the UVA light from the sun, and the heat that comes along with it...
Birds, in contrast, get more than enough Vitamin D, as well as all of the other benefits that they/we might get from natural sunlight, from their/our diets. Commercially available bird diets all contain more than enough of these nutrients to prevent your parrot from needing any type of special light inside...And again, they don't need UVB light in order to be able to process their nutrition like Reptiles do, birds are just like us in that respect. Thus, no need for any type of artificial lighting for your birds...
Also, not all commercially sold bulbs are created equally, and yes, it's true that many, many bulbs can cause blindness in birds, reptiles, amphibians, etc. Most-all COIL/SPIRAL bulbs, whether they are UVB bulbs, UVA bulbs, or an all-in-one Mercury Vapor Bulb, emit harmful light rays as a result of their manufacturing process, and usually cause eye damage, skin damage, and blindness. Most COMPACT, or regular shaped lights are extremely weak and emit not near enough UVB light for reptiles or amphibians, and would not serve any purpose to birds at all...The most highly recommended type of artificial light for reptiles and amphibians are the long, flourescent tube lights that must be put into a long strip light fixture. These UVB tubes emit a strong, efficient UVB light for reptiles that is safe for their eyes and skin. Again, these would serve no purpose at all for a bird's health or well-being.
So what type of artificial light would be beneficial for a parrot? Well, if your house is chilly then a normal flood-bulb for heat (UVA) put near your bird's cage (indirectly, not in their eyes) might help...
