Arcadia 100W Mercury Vapour D3 Basking Lamp

The D3EVO® UV-B Basking Lamp is expertly crafted to deliver vital energy to reptiles in regions with 110-120V power, such as the USA and Canada.

While the classic D3 basking lamp has been a favorite among countless reptile owners, it was originally designed for 230-240V areas. As demand increased in North America, we recognized the need to adapt our top-selling SBMVL for 110V compatibility. Through this process, we discovered that the traditional method of adapting such lamps from 240V to 110V was the root of persistent challenges faced by US keepers using combination lamps over the years.

Arcadia stands as the global leader in UVB lighting, offering unmatched reliability, extended durability, and a pleasant light without the harsh blue/purple tones or annoying flickering found in other bulbs.

UV Index Output:

At 12" distance, no mesh — UVI 6

At 16" distance, no mesh — UVI 4

The basking spot should represent the highest UVI level in your reptile’s habitat. Given its potent UVB output, this lamp is ideal for species requiring significant UVB exposure, including bearded dragons, uromastyx, blue tongue skinks, savannah monitors, tortoises, and freshwater turtles.

Color Temperature: 4800K

Usage Guidelines:

Compatible with standard reptile domes, ensure the lamp is positioned at least 10" from your reptile. For optimal effect, install it on either the far left or right side of the enclosure to establish a beneficial light gradient. In terrestrial setups, the UVB bulb should span roughly half the length of the enclosure.

Note that a mesh top can diminish UVB output and effective range by about 30%.

To ensure consistent performance, replace this bulb annually.

For precise monitoring, we advise using a Solarmeter 6.5 to check the UVB output at the exact distance between the lamp and your reptile, preventing under- or over-exposure.
