A self-ballasted compact fluorescent that puts 5% UVB and 30% UVA into a standard screw socket, so it can go into an ordinary dome fixture without a separate ballast. It is built for small tropical terrariums — arboreal setups up to about 45cm tall, or terrestrial ones up to about 50cm long. Beyond that the output does not spread far enough, and a linear T5 HO tube is the better answer.
Features
- 5% UVB, 30% UVA — for tropical reptiles and amphibians.
- Standard screw base — fits ordinary dome and clamp fixtures; can be mounted vertically or horizontally.
- Self-ballasted — no separate ballast required.
- UVB-transmitting quartz glass.
Distance and replacement
UV Index runs roughly 2.6–3.5+ at 8–10cm and 0.4–0.7 at 20–25cm. Mesh screen cuts output 30–40%. Replace every 6 months — output is at its highest for the first fortnight and declines steadily from there.
