- Arcadia 20W Mini Halogen Heat Lamp – Twin Pack provides two compact, energy-efficient basking lamps designed to deliver bright, bioavailable Infrared-A rich heat for reptiles in smaller enclosures. Arcadia describes the 20W model as a mini halogen designed to run at full capacity while maintaining high levels of usable IR-A throughout the day. Each 2 inch / 50mm lamp uses a wide-beam flood design with a frosted lens and built-in metal reflector to help spread heat and light smoothly into the basking zone. Arcadia positions this new 20W lamp as an energy-efficient alternative to 50W tungsten flood lamps in suitable setups. Why Choose the Twin Pack? The twin pack is ideal for keepers who want a spare lamp ready to hand, run multiple matching enclosures, or simply buy more economically for regular reptile heating use. It offers the same compact footprint and IR-A rich daytime heat as the single lamp, but in a more convenient two-lamp format. This makes it especially useful for smaller vivariums where full-size basking bulbs may be too powerful or oversized, while still delivering bright, efficient halogen heat across the basking area.
