Shabbat lamp

Shabbat lamps for children, such as the teddy bear pictured here, have features for covering the light without tampering with electricity.

The restriction on moving candles may also apply to incandescent lights, which are generally treated in halacha as similar to fires.

[4] Practically speaking, a normal lamp could be covered[5] with a towel or other object (according to some opinions) on Shabbat in order to minimize its light.

However, the Shabbat lamp has a close-fitting cover which is much more effective and safe at producing total darkness.

The 15 watt compact fluorescent bulb (CFL) used also has the benefit of using a minimal amount of energy, as the lamp must remain on for a period of at least 25 hours.
