Biogas can be used in gas lamps to provide illumination, such as lighting for toilets. Biogas lamps are an efficient and affordable alternative to electric bulbs. They can provide lighting similar to a 25-75W electric bulb and can be purchased from manufacturers in China and India. Biogas lamps consume approximately 70 to 150 L/h of biogas.
