One of the easiest and most energy efficient way to light an enclosure is to use LED strips. The White Python LED strips are incredibly easy to install and look great! We use them in many of our vivariums, particularly when we require additional light with adding extra heat.
The modular system allows you to extend or reduce the strip to suit your enclosure. They use adhesive magnetic strips to fix in place, simply uncover the adhesive side and stick the magnetic strip wherever you would like the LED lights to go. There are a variety of extensions and accessories for you to personalize your system.
