Incandescent Aquarium Bulbs
Incandescent bulbs have limited use in aquariums because they give off narrow spectrum light and produce a lot of heat. That said, they can work just fine with very small freshwater aquarium kits or fish bowls with small fish, and are great for reptile terrariums. They are very inexpensive and often come in fun colors. See our small tank and fishbowl lighting fixtures as well!
