Exo Terra Daytime Heat Lamp Bulbs

The Exo Terra Daytime Heat Lamp is a broad-spectrum daylight basking bulb that gives reptiles and amphibians the bright light and radiant warmth they need through the day. It creates a focused basking spot and a natural temperature gradient across the terrarium, so your animal can move between warm and cool zones and regulate its body temperature the way it would in the wild.

What it does

• Broad-spectrum daylight for a bright, natural-looking terrarium
• Radiant heat creates a defined basking spot and a warm-to-cool gradient
• Raises the overall ambient air temperature of the enclosure
• Emits UVA, which encourages feeding, activity, and natural behavior
• Standard screw-in medium base fits common reptile dome fixtures

Choose your wattage

Match the wattage to your terrarium size and how warm you need the basking spot. Higher wattage delivers more heat and a larger warm zone.

Basking temperature also depends on how far the bulb sits from the basking surface, so confirm it with a thermometer and adjust the distance or wattage as needed.

Setup and safety

• Use in a dome or fixture with a ceramic socket, since higher-wattage bulbs run hot
• Mount above a basking surface and check the basking temperature with a thermometer
• This bulb does not produce UVB, so pair it with a separate UVB source for healthy calcium metabolism
• Run it on a daytime cycle and switch to a night lamp after dark rather than leaving a bright light on around the clock

FAQ

Does this bulb provide UVB? No. It gives off visible daylight, UVA, and heat, but not UVB. Reptiles that need UVB for calcium metabolism should also have a dedicated UVB bulb.

Which wattage should I choose? Match it to your terrarium size and target basking temperature, then verify with a thermometer. Larger or taller enclosures and higher basking temps call for more wattage.

Can I leave it on overnight? It is best used on a daytime cycle. For nighttime warmth without bright light, switch to a night heat lamp after dark.

What fixture do I need? A dome or lamp fixture with a ceramic socket rated for the wattage you choose, since these bulbs get hot.
