Using this clamp lamp is easy. First, find a suitable place near your reptile's habitat and clamp the lamp securely. Then, insert your Reptile Systems Ballasted Mercury Vapor or Basking Spot lamp into the ceramic holder. Make sure the lamp is properly connected and turned on to provide the right amount of light for your reptile. When it comes to maintenance, keep the lamp clean by gently wiping the reflector with a soft, dry cloth. Avoid using any harsh chemicals as they may damage the lamp. Also, always check the lamp regularly for any signs of wear or damage and replace it if necessary. And remember, when you're not using the lamp, turn it off to save energy and extend its lifespan.
