Reptile vivariums require constant heat and UVB lighting for your pet's health, with a typical bearded dragon setup using 100-150W for heat lamps plus 20-40W for UVB. Running a complete vivarium 12 hours daily costs $6-10/month, but many keepers don't realize ceramic heat emitters (CHE) running 24/7 in winter can double these costs.

Check your device label or manual for wattage
Default: $0.16/kWh (America average)
⚠️ These are estimates based on continuous usage at the specified wattage. Actual costs may vary based on usage patterns, thermostat cycling, and local electricity rates.
Average running costs for a 150W Reptile Vivarium at $0.16/kWh (US average)
| Usage | Energy (kWh) | Cost (USD) |
|---|---|---|
| 1 Hour | 0.15 | $0.024 |
| 8 Hours/Day | 1.20 | $0.19 |
| Per Month (30 days) | 36.00 | $5.76 |
| Per Year (365 days) | 438.00 | $70.08 |
* Based on 8 hours daily usage. Use the calculator above for your specific usage pattern.
Use a thermostat controller (not just a timer) - prevents overheating and reduces runtime by 30-40% vs uncontrolled bulbs
Insulate the vivarium back and sides - reduces heat escape and allows using a lower wattage bulb to maintain proper temperatures
Switch to halogen flood bulbs instead of incandescent basking bulbs - they produce more heat per watt and cost 20-30% less to achieve the same basking spot temperature
A typical setup costs $6-10/month: 100W basking bulb (8 hours) = $3.84/month, 75W ceramic heat emitter overnight (10 hours) = $3.60/month, 22W UVB tube (10 hours) = $1.06/month. Total: approximately $8.50/month at $0.16/kWh. Winter months may be 20-30% higher.
No. Basking lamps mimic daytime sun and should run 10-12 hours only. Use a ceramic heat emitter (CHE) or deep heat projector for nighttime if temperatures drop below 65°F. A thermostat is essential - it cycles heating on/off to maintain target temps and prevents energy waste.
