1. Safety instructions

• Do not operate the lamp with a voltage higher

than 12 V.

• Do not subject the light source to mechanical

shocks or vibrations.

Caution! Lamps become hot when operated for long
periods! There is a risk of burning!

• Do not touch a hot lamp.

• After a long period of operation, allow the lamp

to cool for at least 20 minutes.

The light becomes very intense.

• Do not look directly into the lamp.

The grease from your hands will smudge the lamp
and considerably reduce its operating life.

• Do not touch halogen lamp bulbs with your

fingers, for example when changing a bulb. In­stead use a cloth or a similar form of protection.

Optical components from the Kröncke optical system

• Set up the experiment.

• Mount the halogen light source on the optical

rider K in the vertical or horizontal position ac­cording to preference, and connect it to the
transformer.

• Carry out the experiment.

5. Changing the bulb

• Disconnect the voltage supply from the halogen

light source.
