Sajid and his team developed their adaptation of Liter of Light and named it Botol Bati (Solar Bottle Light). Botol Bati is based on the similar technology of reusing empty plastic bottles as lights. It is constructed using empty bottles, tin sheds (1 ft by 1ft), silicon glue, chlorine, and clean water. The bottle lights are placed in the roofs of the houses and produce at least 60 watts of equivalent light. With the support and guidance from Sustainable Development for Energy Programme of the German Development Cooperation (GIZ), 250 Botol Batis were installed in the Baonea-badh slum of Mirpur, Dhaka. It covered households, toilets, and cottage industries in the area. Around 5,500 people were direct and indirect beneficiaries of the initiative.
