3‑in‑1 light bulb for turtles and agamas

This 80 W mercury vapour bulb is intended for keepers of land tortoises, bearded dragons and skinks that need UVB and UVA exposure. It replaces a separate UV tube and heat source, so one fitting covers basking heat, visible light and UV.

Why it matters

• Single source for three functions: it emits UVB, UVA, visible light and infrared heat, so the enclosure needs only one fitting.
• UVB output for bone health: the UVB supports vitamin D3 synthesis, which the manufacturer links to preventing or reversing metabolic bone disease.
• Built-in ballast: no external ballast is required, and the bulb fits a standard E27 screw socket.
• Long service life: rated for up to 6000 hours, with an average of 8 to 12 months under normal use.

What it works with

The bulb is suited to enclosures for tortoises, bearded dragons and skinks that bask on the ground and require UVA and UVB. Its large UVB projection area gives a wider basking zone. It can be combined with Arcadia linear reptile lamps to create a directional light gradient across the enclosure.
