Question
Hello Rabbi, Is it permissible to sit under a lamp attached to the sukkah roof? Is there any significance in attaching the lamp to the sides or sitting directly under the roof? Thank you very much.
Answer
Hello,
It is not permissible to hang decorations under the sukkah roof within a distance of four tefachim, and even with objects, more than four tefachim is required to be allowed to sit under them.
However, with a lamp, since it is important to keep it away from the roof to avoid the danger of fire, it is permissible from the outset to distance it from the roof by more than four tefachim.
It is permissible to hang decorations and the like within the measure of four tefachim to the roof, even if they hang below this measure.
The measure of four tefachim should be calculated stringently as 32 cm.

Nevertheless, regarding hanging lamps in the sukkah opposite the table, there is no need to be stringent that they be within four tefachim, and on the contrary, it is better and more correct to distance them from the roof as much as possible.
