The light/dark test is based on the innate aversion of rodents to brightly illuminated areas and on the spontaneous exploratory behaviour of rodents in response to mild stressors, that is, novel environment and light. The test apparatus consists of a small dark safe compartment (one third) and a large illuminated aversive compartment (two The light/dark box test, traditionally used to quantify rodent anxiety-like behavior, has recently been applied to the adult zebrafish (Danio rerio).

The UV Intensity test side can be used in a closed box or directly under the light. This test gives an indication of the UV or UVC remaining in the bulb depending on the time you leave the card exposed to the light. A test light is a simple device that can tell you if power or ground is present at a particular circuit or fuse. The test light consists of a sharp probe, indicator light bulb and a wire lead with a clip.

The light–dark preference test is one of the most commonly used anxiety models in animal preclinical studies. This test assesses spontaneous/natural tendency of an animal to explore/avoid certain zones of a given environment, for instance a half black-half white box. This test has been validated for use in adult but not larval zebrafish. Turn Off Power to the Light at the Breaker Panel Box and Remove the Socket. Turn the power off to the socket. Test the socket by attaching the clip of the continuity tester to the hot screw terminal, the black wire lead. Then, touch the probe to the metal tab in the bottom of the socket. The tester should glow.
Hold the photometer directly in the path of the brightest beam. Move it around until you find the spot with the maximum intensity (illuminance). Staying the same distance from the light source, move the photometer in one direction, until the light intensity drops to 50% of the maximum level.
