In the same center, we saw a lot of other people using similar outdoor goods. A flashlight only gives focused light and does not light up the entire room. The lantern for outdoor use that we had was an excellently bright source of light in this respect. In order to provide light for an entire room using a flashlight, place a creased sheet of aluminum foil on the ceiling. Put a flashlight under it and the light will be irregularly reflected, brightening up the whole room to a surprising degree.
Outdoor equipment is indeed very useful in survival situations.
If you have such equipment stored in a van, this can become a kind of emergency shelter. We know that many of those who had these outdoor goods and equipment in their cars made use of them and pitched tents in parks or primary schools, making them into their temporary home. When I place large piece of furniture or equipment in the house, I use a thin piece of wood wrapped in newspaper to wedge under the item so that the front is 2 to 3 cm higher, making it lean back onto the wall. Because of this precaution, my furniture did not fall over in the earthquake. When the earthquake hit, this box acted as a kind of support and prevented the cupboard from falling down.
