Exo Terra Sun-Glo Neodymium A21 Lamp 100W – 4 Pack Daylight Terrarium Lighting

Product overview

Set up reliable daylight and warmth in your terrarium with the Exo Terra Sun-Glo Neodymium A21 Lamp. This four-pack of 100-watt daytime heat lamps delivers robust, broad-spectrum light designed to illuminate your enclosure with a natural color balance. The glass sleeve contains Neodymium, a rare-earth element that subtly shifts the color balance to resemble daylight more closely, helping plants and enclosure inhabitants appear more true-to-life under your viewing window. Note that these bulbs do not emit UVB; instead, they deliver UVA light as part of a complete lighting strategy for daytime activity and warmth.

Why this matters in a terrarium

In many terrarium setups, heat and light must work in harmony. The broad spectrum supports plant photosynthesis and helps maintain comfortable daytime temperatures across basking zones. With UVA emitted, you may notice more natural basking, foraging, and activity patterns in your reptiles, while plants maintain a healthy growth appearance under the spectrum.

Real-world benefits you may notice

In a well-lit vivarium, the warm glow from these lamps often highlights the textures of plant leaves and reptile scales, creating a more immersive viewing experience. The combination of heat and light can support routine behaviors and the general sense of a thriving habitat. While individual results vary, many keepers find the setup helps maintain stable daytime warmth and visually balanced illumination that supports plant and animal life alike.
