The Reptile Systems ceramic clamp lamp is ideal for use with self-ballasted mercury vapour, basking spot lamps and ceramic heaters. The holder is made of ceramic so it will not melt like some plastic fittings would, making them extra safe to use. The clamp itself is extremely robust and comes with a hard-wearing rubber grip and clamp. They can be placed inside wooden vivarium’s, or mounted over tortoise tables, glass terrariums and screen cages.
