Choosing the Right UVB Level

5% UVB is generally recommended for many tropical, forest-dwelling, and lower UV-demand species where animals can bask relatively close to the bulb.

10% UVB is better suited for species that require stronger UV exposure, larger enclosures with greater mounting distances, or habitats designed for higher UV-demand reptiles.

Always provide appropriate basking distances, shade areas, and follow species-specific UVB recommendations.
