Why this matters
After comparing dozens of bulbs, we found that cheap glass bulbs often shatter from thermal shock. Ceramic emitters and reinforced glass models are safer and more durable for daily use.

Key Buying Factors
01
Heat Output and Coverage
Look for bulbs that produce enough heat to create a basking spot of 95-110°F for desert reptiles, or 85-90°F for tropical species. Spot bulbs focus heat, while emitters spread it.
02
Bulb Lifespan
Incandescent bulbs typically last 2000-3000 hours. Infrared emitters can last 5000+ hours. Longer life saves money and reduces replacement hassle.
03
Safety Features
Choose bulbs with ceramic bases to avoid cracking. Ensure the fixture has a porcelain socket and is rated for the bulb's wattage to prevent overheating.
04
Compatibility with Fixtures
Most bulbs fit standard 5.5-inch domes. Check the maximum wattage rating of your fixture. Some infrared emitters require a special dimmer or thermostat.
05
Light Spectrum
Daylight bulbs mimic natural sunlight for basking. Infrared bulbs produce no visible light, ideal for nighttime heating without disturbing sleep cycles.
06
Durability
Look for bulbs with reinforced filament or thick glass. Ceramic emitters are more durable than glass bulbs and resistant to thermal shock from water splashes.
Section 05
Care, Cost and Maintenance
Proper Placement
Position the heat lamp above a basking branch or rock, ensuring the reptile can get within 6-12 inches for optimal warmth. Create a temperature gradient across the enclosure.
Temperature Monitoring
Use a digital thermometer with probe to measure basking surface temperature. Adjust bulb wattage or distance to achieve the recommended gradient for your species.
Bulb Replacement Schedule
Replace incandescent bulbs every 6 months even if they still emit light, as heat output degrades. Infrared emitters can last up to a year but check for dimming.
Pro tip
Always use a thermostat with your heat lamp to prevent overheating. It automatically turns off the bulb when the basking area reaches the target temperature, saving energy and extending bulb life.
Frequently asked questions
Can I use a regular household bulb for my reptile?
No. Household bulbs don't produce the proper spectrum or heat distribution. They can overheat or break, and may emit light that disrupts your reptile's day/night cycle.
How do I choose the right wattage?
Start with a 75-100W bulb for a 20-gallon enclosure. Monitor the temperature at the basking spot and adjust distance or wattage. For larger tanks, consider multiple bulbs or higher wattage.
Do I need a special fixture for heat lamps?
Yes. Use a dome fixture with a porcelain socket rated for high wattage. The dome reflects heat downward and protects against accidental contact.
Can I leave a heat lamp on all night?
Only if you use an infrared heat emitter. White light bulbs will disrupt sleep cycles. For nocturnal heating, choose a ceramic emitter or a red/black bulb.
How often should I replace my heat bulb?
Incandescent bulbs should be replaced every 6 months even if they still light, as heat output diminishes. Infrared emitters last 12-18 months but check for cracks.
