Zoo Med Basking Spot Lamp, 2 Pack, 75 Watts

Two 75 W glass lamps come in this reptile basking spot lamp pack from Zoo Med, model SL-100. Each bulb is 7.6 x 7.6 x 10.2 cm and weighs 91 g, and the white finish sits behind the reflector. The maker says the pair suits diurnal reptiles that regulate heat by basking.

Inside the two-lamp pack

The pack holds two lamps, each one a Zoo Med Repti Basking Spot Lamp. Both are made of glass and measure the same: 7.6 cm long, 7.6 cm wide and 10.2 cm high, or 3 x 3 x 4 in. Each lamp weighs 91 g (3.2 oz).

Does this lamp suit your reptile and setup?

The manufacturer lists this lamp for diurnal reptiles, meaning animals that are active in daylight and control their temperature by moving to and from a basking spot. If your animal is nocturnal, or if you keep a species that does not bask, the maker's stated use does not cover it.

Each lamp draws 75 W, so check that the fixture you plan to use is rated for that wattage before you fit a bulb. The lamp also raises the ambient air temperature of the terrarium, which affects the whole enclosure rather than only one corner, so measure the temperature at both the basking site and the cooler end before you settle on a position.

75 watts of power from each lamp

Each bulb in the pack puts out 75 W. The maker lists energy efficiency among the lamp's special features alongside that figure. The same lamp is described as producing UVA rays, and its double reflector is built to direct 35% more heat and light than a regular spot lamp does.

How the double reflector shapes the basking site

Inside each lamp, a double reflector concentrates the output into a tighter beam than an ordinary reflector bulb produces. That tighter beam carries heat to one specific area, which gives your reptile a defined basking site instead of a broad wash of warmth across the terrarium. The same beam supplies the UVA rays the maker attributes to the lamp.

Because the beam is narrow, the basking spot sits where you aim the fixture, and the rest of the enclosure stays outside the direct beam while the ambient air still warms. The lamp is made of glass, and the white body measures 3 x 3 x 4 in.
