Exo Terra Moonlight UVA LED NANO 5W Reptile Night Bulb PT2367

The ET Moonlight UVA LED NANO 5W is a low-energy nocturnal lighting bulb designed for reptile, amphibian, and invertebrate keepers who want to observe their animals at night without disrupting natural behaviour. Emitting a soft ultraviolet light that mimics the UV output of moonlight, it enables genuine nocturnal viewing without triggering a day response or interfering with natural night-time temperature drops.

What UVA moonlight actually does

This bulb produces UVA light in the nocturnal spectrum, replicating the subtle UV rays present in natural moonlight. Beyond illuminating the enclosure for the keeper, UVA at this wavelength has a documented effect on certain invertebrates — causing scorpions, some spiders, spider webs, insects, mushrooms, and even minerals to fluoresce visibly. It has also been noted to stimulate mating behaviour in some spider species, making it a genuinely functional tool for invertebrate keepers, not just an aesthetic one.

Energy use and temperature

At 5W, this bulb consumes approximately 70% less energy than a conventional night light of equivalent output. Crucially, it produces negligible heat, meaning it will not raise ambient temperatures overnight and won't compromise the natural thermal drop that many reptiles and amphibians depend on for healthy thermoregulation and circadian rhythm.

Nano enclosure compatibility

• Sized specifically for use with the Exo Terra Reptile Dome NANO fixture, designed for NANO and MINI terrariums
• Can be paired with a Daylight Basking Spot NANO or Reptile UVB NANO bulb to build a complete lighting setup tailored to your animal's UV, light, and temperature requirements
• Intended for reptiles, amphibians, and invertebrates only — not a general-purpose bulb

For keepers running a NANO or MINI setup who want a proper nocturnal lighting solution rather than a crude workaround, the ET Moonlight UVA LED NANO 5W delivers both the viewing experience and the biological respect your animals require.
