Prefab light bulbs for prefab housing


If your house is going to be prefab then why can’t your light bulb be prefab as well? Isang Literong Liwanag or A Litter of Light is an innovative renewable lighting solution for the poor that requires nothing but solar energy for illumination.

This cheap, solar-powered bulb is actually just clear plastic soda bottles filled with a mixture of purified water and chlorine or bleach which is commonly used in household cleaning products. Inserted halfway into a hole on the roof and sealed around the rim to avoid leakage. These DIY solar powered bulbs can give off light equivalent to a 55-watt electric lamp as the water inside the bottle refracts sunlight and other exterior light.

Thousands of these lights have been installed in the slums around Manila. Litter of Light is a perfect lighting solutions for disaster stricken areas with make shift homes. Countries like Pakistan with grave electricity shortage should install such light in schools and offices to reduce the strain on the national grid and reduce energy cost as well.
