We will be on a cruise during Shabat where lighting a fire is strictly forbidden. Can we use a flashlight for hadlokas neiros and havdaleh instead ? Thx
It is controversial if we may use a flashlight for hadlokas neiros, therefore you should use it, but it is better not tot make a bracha when you light them. Regarding havdalah it is also controversial, but for more reasons. The main one is that it isn’t enough of a fire to make borie meorei haesh on it. Therefore you may use the light of the flashlight, but don’t make a bracha on it. This would especially apply if the flashlight is only LED or a fluorescent bulb.
