Choosing heat and light bulbs for your box turtle’s home is only half the battle. Then you need to decide what lamp fixture to use. One with a ceramic socket is always a good choice. It will let you use the widest variety of bulbs.
So if you decide to try a different bulb, you’ll still be able to use the same lamp fixture. Most of the time, anyway.
This Deluxe Porcelain Clamp Lamp is a solid choice. It does have a porcelain socket. It clamps securely to the habitat or another sturdy object. And you can cover it to protect you and your pets from burns.
