⚠️ Caution May be okay in small amounts or specific forms — read the details.

UVB bulbs are not food and should never be eaten. While the glass itself is not toxic, breaking the bulb releases mercury vapor, which is dangerous. Turtles should not chew on or touch broken glass shards.

⚠️ Emergency: Possibly — call your vet for advice.

💡 Why

UVB bulbs contain mercury, a heavy metal that is toxic if inhaled as vapor or ingested in large quantities. The primary risk is physical injury from broken glass and potential mercury exposure if the bulb shatters. Intact bulbs are safe for external use but pose a hazard if damaged.

🩺 What to do

  1. Keep UVB bulbs out of reach of turtles to prevent chewing or knocking them over.
  2. If a bulb breaks, ventilate the area immediately and avoid direct contact with shards.
  3. Wear gloves when cleaning up broken glass to protect against cuts and mercury exposure.
Important: this is for reference only and is not veterinary advice. If your turtle may have eaten or touched something dangerous, contact your veterinarian immediately.

❓ Common questions

What if my turtle chews on the bulb?

If the bulb is intact, it is likely just a hard surface, but check for any glass fragments in the mouth. If the bulb broke, seek veterinary care immediately.

Is mercury in UVB bulbs dangerous to turtles?

Yes, mercury is toxic. While the amount in a single bulb is small, inhalation of vapor or ingestion of broken glass with mercury residue can cause harm.

How should I store spare UVB bulbs?

Store them in a secure, high location away from the turtle's enclosure to prevent accidental access or breakage.
