Florescent and Incandescent Light Bulbs With Regards to Shabbat

Florescent and Incandescent Light Bulbs With Regards to Shabbat
Day: Monday
Date: December 14, 2015
Parshat: Vayigash
Yalkut Yosef: O"H: 345


When there is a need to turn on a light on Shabbat for a person who is in serious danger, there are those who maintain that it is better to turn on a florescent light rather than an incandescent one. Their reasoning is such since an incandescent light bulb involves three melachot, lighting a fire, cooking, and building, while the florescent light bulb involves only two since it does not have a filament that heats up. However the truth is that the florescent bulb involves more melachot since turning it on causes three separate electronic ignitions. Conversely, since we do not consider turning on the incandescent bulb to be a form of building, doing so involves only two melachot and therefore that would be better.
Turning off electricity on Shabbat is forbidden on a Rabbinic level. Even if there is no light bulb involved, there is nevertheless always a spark of two created which makes it Derabanan.
