Heat Cord: Size : 9m - 80W This is the break-through in heating that we have all been waiting for at a very reasonable price. These heating cords are ideal for use in vivariums or incubators; no more changing blown globes all the time! You can place them behind a false wall or under a false floor. The list of uses for this heating cord is endless, you can even use it in your outside pits or enclosure because it is WATERPROOF. Fauna rescue groups also love these heating cords as it helps keep a larger percentage of their rescued animals alive and we think that's great! Available in four sizes and wattages. Wired to Australian Standards.
