Arcadia D3 Forest UVB 7% 13W Compact Lamp

The Arcadia D3 Forest Compact UVB Lamp 7% – 13W is a full-spectrum compact fluorescent designed to simulate natural sunlight for forest and mixed-habitat reptiles. It provides 7% UVB to support natural vitamin D₃ synthesis, plus 30% UVA to encourage normal activity and colour perception.

Compact UVB lamps can be especially useful for keepers of young or smaller animals, or for providing UV in smaller to medium enclosures where a full-length T5 system isn’t practical.
