Exo Terra Sun-Glo Basking Infrared Spot Lamp 100W (4 Pack) – Tight Beam UVA

Upgrade your reptile enclosure with the Exo Terra Sun-Glo Basking Infrared Spot Lamp. This four-pack of 100-watt lamps is designed to deliver a tight, directional beam that creates a dedicated basking spot wherever you need it in the terrarium. The compact size makes it easy to position on branches, rocks, or mounted fixtures, so you can tailor the warm zone to your terrarium’s layout.

With a beam that increases light and heat by about 35%, you can place the lamp farther from the basking site while still achieving the warm, radiant area your reptile prefers for thermoregulation. The result is a steady, localized heat zone that supports daytime activity and comfort as your reptile explores its habitat. The ambient air temperature around the basking spot rises, helping to establish a stable microclimate for daily routines.

UVA benefits and behavior

The Sun-Glo lamp emits UVA rays, which can contribute to a sense of well-being in reptiles and may help stimulate breeding behavior. This is presented as a potential natural cue rather than a guarantee of results, aligning with an observational approach to terrarium care. Replacing or supplementing light with a reliable source can be part of a thoughtful habitat setup.

What you get and how to use it

• Pack of 4 Exo Terra Sun-Glo Basking Infrared Spot Lamps, 100-Watt/120-Volt
• 35% higher light and heat within the beam for more efficient basking zones
• S25 bulb design for compatibility with Exo Terra fixtures
• Works with Night Glo or Heat Glo bulbs to support a 24-hour cycle

Practical setup and benefits

Use the tight beam to establish a precise basking area on a rock, log, or platform. The stronger beam means you can position the lamp at a greater distance while preserving a warm zone, promoting comfortable thermoregulation and daytime activity. The ambient air temperature in the enclosure rises with the beam, helping create a stable microclimate that supports your reptile's daily routine.

For real-world scenarios, many keepers place multiple lamps to cover separate basking spots or to extend the warm zone along a preferred path. The four-pack also gives you replacement options or coverage for multiple enclosures, ensuring consistent lighting across your reptile collection. With careful placement, you can tailor heat distribution to seasonal changes and individual reptile preferences.

Tips for safe, effective use

Always use in a compatible fixture and follow manufacturer instructions for bulb replacement and enclosure setup. Check another lamp's wattage and compatibility to prevent overheating and ensure safe operation in your terrarium. Regular monitoring helps maintain steady conditions and avoids hot spots.
