2. Fixture Placement

The fixture can be placed directly on a mesh cage top or hung using the included hook.

  • On Mesh Cage: Place the dome directly on the mesh top of the terrarium, ensuring it is stable and the bulb does not touch the mesh.
  • Hanging: Use the integrated hook to hang the fixture from a light stand or other secure support above the terrarium. Ensure adequate clearance between the bulb and any surfaces.

3. Temperature Probe Placement

Fix the temperature probe to the desired area within the terrarium where temperature monitoring is critical. Use the suction cup to secure it to the glass or a smooth surface. Ensure the probe is not directly under the heat lamp to avoid inaccurate readings, but rather in the basking or ambient temperature zone you wish to control.
