When to use LED lighting
Jungle Dawn LEDs are one of the most versatile solutions, due to the low heat output, low wattage, bright light output, and ideal color temperature. Since they are unidirectional & available in a wide variety of sizes, they are well suited for any terrarium ranging from 12" to 36" high. Fixtures for these are currently limited to 36" wide (Exo Terra's largest compact top), but using two hoods per enclosure is common practice for wider enclosures. Breeder customers & commercial clients often use custom "side mounted fixtures" in rack shelving, and for custom installations. These aren't
the best solution to those building on a tight budget, or for those working with shorter terrariums under 13" high.
We are not describing cheap Chinese generic LEDs. In our testing of three different types of "corn cob" style LED bulbs, none produced significantly less heat than a low-wattage CFL, and one of the three bulb types we tested began melting in it's deep-dome housing before an hour of use.
