While Ireland recently banned plastic bags, here's how the little town of Sitio Maligaya, municipality of Mariveles, Bataan Province, the Philippines dealt with their unwanted plastic (2:15 video).
A little inexpensive bleach "softens" the light, making it more uniform and diffuse, and lessens the glare. It's as bright as an incandescent bulb! FYI, the residents of the town are speaking native Tagalog.
