Buying Guide
What to consider when choosing UVB/UVA bulbs
- Tank size and basking distance: Higher wattage requires careful placement to avoid overheating.
- UVB output needs by species: Some reptiles need strong UVB for calcium metabolism, others require moderate exposure.
- UVB longevity and replacement cadence: Bulbs with slow degradation reduce maintenance but may still require periodic changes.
- Fixture compatibility: Self-ballasted bulbs work with standard fixtures, but check your lamp type before purchase.
- Heat vs. light balance: Some bulbs combine heat with UV, while others separate functions—choose based on your habitat’s design.
How to set up for optimal reptile health
