Section 03
Key Buying Factors
01
Light Spectrum
Look for bulbs that emit UVA and UVB rays to support vitamin D synthesis and natural behaviors.
02
Wattage & Coverage
Choose wattage based on enclosure size; larger tanks may need 100-150W to create a proper basking gradient.
03
Durability
Ceramic emitters last longer than incandescent bulbs, while halogen bulbs offer bright light. Consider replacement frequency.
04
Safety Features
Ensure the lamp housing is ceramic or metal with a built-in guard to prevent burns and reduce fire risk.
05
Heat Distribution
Some lamps focus heat in a tight spot, others spread it. Match to your reptile's basking needs.
06
Ease of Installation
Clamp lamps and dome fixtures should have secure mounts and adjustable necks to direct heat precisely.
Section 05
Care, Cost and Maintenance
Set Up the Gradient
Place the lamp at one end of the enclosure to create a warm basking spot (90-110°F) and a cooler side (70-80°F) for thermoregulation.
Monitor Temperature Regularly
Use a digital thermometer or temp gun to check basking surface temperature and ambient air. Adjust lamp height or wattage as needed.
Replace Bulbs on Schedule
UVB output declines over time; replace bulbs every 6-12 months even if they still light up. Follow manufacturer recommendations.
Pro tip
Always position the lamp outside the enclosure or use a guard to prevent burns. Reptiles can climb and get too close-safety first.
Frequently asked questions
How far should the heat lamp be from my reptile?
We recommend 10-12 inches for most basking bulbs, but check the bulb's instructions. Use a thermometer to ensure the basking spot reaches the correct temperature.
Can I use a heat lamp 24/7?
No, reptiles need a day-night cycle. Turn off the heat lamp at night unless you use a ceramic heat emitter, which emits no light. Provide 10-12 hours of light daily.
What wattage do I need?
For a 20-gallon tank, 50-75W is typical. For larger enclosures (40+ gallons), 100-150W may be needed. Start with lower wattage and adjust based on temperature readings.
Is UVB necessary with a heat lamp?
UVB is essential for many reptiles to synthesize vitamin D3 and prevent metabolic bone disease. If your heat lamp doesn't emit UVB, you should add a separate UVB source.
How often should I replace the bulb?
Incandescent bulbs last about 3-6 months. UVB bulbs lose effectiveness over time and should be replaced every 6 months to a year, depending on the brand.
