Zoo Med Repti Basking Spot Lamp (50W)
The basking bulb reptile keepers reach for most. The Zoo Med Repti Basking Spot uses a double reflector to throw a tight, focused beam that raises the basking surface temperature efficiently, and it is sold in 25, 40, and 50 watt so you can match the wattage to your tank. It gives the heat and bright UVA daylight a leopard gecko wants (it is not a UVB bulb), it is cheap, and it is stocked everywhere. Pair it with a thermostat or dimmer and it is the reliable, right-beam pick.
View on Amazon Editorial illustration.Leopard geckos bask to a fairly low surface temperature, around 90 to 95 degrees, so the goal is a focused spot bulb at a wattage that warms the basking spot without cooking a small tank. In a 10 to 20 gallon enclosure a 50 watt can run hot, so a 25 to 40 watt is often safer, and you should always control it with a thermostat or dimmer and check the surface temp. Look for a tight-beam basking spot bulb, wattage matched to your tank size, and a thermostat.
How do the best options for basking bulb for a leopard gecko compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Zoo Med Repti Basking Spot Lamp (50W) | The basking bulb reptile keepers reach for most. |
| Broad daylight | Exo Terra Sun Glo Halogen (50W) | A halogen spot that gives a broader-spectrum daylight and efficient heat, again in a focused beam. A nice option if you prefer a whiter light over the enclosure; like the top pick it provides heat and UVA, not UVB. |
| Lower wattage | Fluker's Incandescent Basking Spotlight (40W) | A 40 watt spot that runs cooler, a smart choice for a small tank or a warm room where a 50 watt would push the basking spot too hot. Same idea: focused heat and UVA, paired with a thermostat and a check of the surface temp. |
What should you look for in basking bulb for a leopard gecko?
A few things separate a good basking bulb for a leopard gecko from a frustrating one: focused spot beam, right wattage, use a thermostat, and heat and uva. Weigh these before you buy.
- Focused spot beam: a reflector bulb that heats the basking surface.
- Right wattage: 25 to 40 watt for small tanks; 50 watt can overheat them.
- Use a thermostat: a dimmer or thermostat to hold ~90 to 95 degrees.
