Reptile Systems Gold Infrared Replacement Lamp

The Reptile Systems Gold Infrared Replacement Lamp delivers high-output infrared heat with minimal visible light, making it one of the most naturalistic heating options available for vivarium and terrarium setups. Available in multiple wattages to suit enclosures of different scales, this is a replacement lamp designed for use with the Gold Infrared Lamp Unit.

What infrared heating does for your reptile

Infrared radiation — particularly IR-A (near infrared, approximately 700–1400nm) and IR-B (approximately 1400–3000nm) — penetrates the skin and contributes directly to thermoregulation at a physiological level. Unlike ambient heating, this interaction supports digestion, promotes natural activity, and contributes to overall well-being in a way that mirrors how solar energy functions in the wild. Because infrared does not rely on visible light, it causes no disruption to the day/night cycle, reducing stress for the animal.

How the technology works

Infrared heat is direct — it is not dispersed or diminished by air movement, which makes it significantly more efficient than conventional basking spot lamps at transferring energy. The heat projects across a wide area rather than a concentrated point, giving the animal a more natural, graduated basking zone. Surrounding surfaces absorb and re-radiate that energy, replicating the radiative warmth of sun-warmed substrate. This produces all three modes of heat transfer — radiation, conduction, and convection — within a single enclosure.

The gold lamp explained

The distinctive gold metallic appearance is a characteristic of the lamp when cold and unlit. In operation, visible light output is kept to a minimum — infrared sits just beyond the visible spectrum, so the lamp produces only a very faint warm glow rather than the bright light of a standard basking bulb. This makes it well suited for use as a primary heat source without compromising lighting schedules.

Using it correctly

• Must be used with a dimming thermostat — do not run uncontrolled
• Rich in IR-A and IR-B for physiologically relevant heat delivery
• Suitable as the primary heat source within the enclosure
• Available in a range of wattages — select the appropriate output for your enclosure size and target temperatures
• Compatible with the Gold Infrared Lamp Unit

Selecting the correct wattage for your setup is essential. Use the variant options on this page to choose the output that matches your enclosure volume and the thermal requirements of your species — and always pair with a quality dimming thermostat for accurate, safe temperature control.
