Bearded dragons are desert reptiles that need a hot basking spot to digest food and stay healthy. Getting the right heat lamp — and the right wattage — is essential, and getting it wrong (or using a heat mat instead) is a common cause of a dragon that won’t eat.
This guide covers the best heat lamps and basking bulbs for bearded dragons, plus nighttime heating.
Our Top Picks at a Glance
| Pick | Product | Best for |
|---|---|---|
| Best basking bulb | Zoo Med Repti Basking Spot Lamp | Most setups |
| Good alternative | Fluker’s Basking Bulb / Arcadia Halogen | Value and output |
| Best nighttime heat | Ceramic heat emitter (CHE) | Cold rooms at night |
What Kind of Heat Lamp Do Bearded Dragons Need?
Bearded dragons need overhead heat from a basking bulb — not belly heat. In the wild, they bask in the sun from above, and that’s what you’re recreating.
- Halogen or incandescent basking bulb — the standard choice. Produces heat plus bright, natural-looking light.
- Ceramic heat emitter (CHE) — produces heat with no light. Use it only for nighttime heat (or 24/7 supplemental heat) so you don’t disturb the day/night cycle.
What Wattage Should You Use?
There’s no single “correct” wattage — it depends on your enclosure size, room temperature, and lamp distance. As a starting point:
| Enclosure size | Typical wattage |
|---|---|
| 20–40 gallons | 75–100W |
| 40–75 gallons | 100–150W |
| 4x2x2 ft (120 gallons) | 100–150W (often two bulbs or a higher-wattage setup) |
The only way to know it’s right: measure the basking surface with an infrared temperature gun — target 100–110°F for babies, 95–105°F for adults. Adjust wattage or lamp height until it’s in range.
Why You Should Use a Dimming Thermostat
A dimming thermostat (like a Herpstat or Exo Terra dimming thermostat) automatically adjusts the bulb to hold a steady basking temperature. It’s the single best upgrade for safety — it prevents dangerous overheating and keeps temps stable as your room temperature changes.
What to Avoid
- Heat mats / heat rocks — bearded dragons need overhead heat; under-tank heat can cause severe burns and doesn’t warm them the way they need.
- Red or “night” bulbs — they can disrupt sleep. Use a ceramic heat emitter for nighttime heat instead.
- Unregulated bulbs — without a thermostat, a hot day can push the enclosure into dangerous territory.
Day & Night Heating Setup
- Day: basking bulb on 12–14 hours (use a timer), UVB tube on the same schedule.
- Night: all lights off. If the room drops below 65°F, add a ceramic heat emitter (on a thermostat).
- Measure: basking surface 95–110°F, cool side 75–85°F.
