It is often necessary to change the intensity of a light on Shabbat. Even if a timer is available (for instance, in a hotel), it is not always easy to predict in advance exactly when the lights will be needed.
In addition, a light is often needed unexpectedly – for example, if a baby wakes up – after which it must be turned off again. In a child's room we might want to turn the light off before the timer disconnects the electricity in the rest of the house. On the other hand, people who have trouble sleeping might wake up in the middle of the night and want a light. And often no Shabbat timer is available, as in many hotels.
The Or-Li Shabbat Lamp was invented in order to solve these problems. A flexible black cover has been designed to fit on a common type of table lamp. The cover can be turned at any angle, allowing more or less light through – from full light to total darkness.
The Or-Li is simple to operate and completely safe to use. It uses a PL fluorescent bulb, which is relatively cool and saves on the cost of electricity. From the halachic point of view it is not considered a flame, avoiding the halachic problem of muktzeh – a rabbinical prohibition to handle it on Shabbat.
