Over one‐quarter of the world’s population relies on fuel‐based lighting. Kerosene lamps are often located in close proximity to users, potentially increasing the risk for respiratory illnesses and lung cancer. Particulate matter concentrations resulting from cook stoves have been extensively studied in the literature. However, characterization of particulate concentrations from fuel‐based lighting has received minimal attention. This research demonstrates that vendors who use a single simple wick lamp in high‐air‐exchange market kiosks will likely be exposed to PM 2.5 concentrations that are an order of magnitude greater than ambient health guidelines. Using a hurricane lamp will reduce exposure to PM 2.5 and PM 10 concentrations by an order of magnitude compared to using a simple wick lamp. Vendors using a single hurricane or pressure lamp may not exceed health standards or guidelines for PM 2.5 and PM 10 , but will be exposed to elevated 0.02–0.3 μm particle concentrations. Vendors who change from fuel‐based lighting to electric lighting technology for enhanced illumination will likely gain the ancillary health benefit of reduced particulate matter exposure. Vendors exposed only to ambient and fuel‐based lighting particulate matter would see over an 80% reduction in inhaled PM 2.5 mass if they switched from a simple wick lamp to an electric lighting technology. Practical Implications Changing lighting technologies to achieve increased efficiency and energy service levels can provide ancillary health benefits. The cheapest, crudest kerosene lamps emit the largest amounts of PM 2.5 . Improving affordability and access to better lighting options (hurricane or pressure lamps and lighting using grid or off‐grid electricity) can deliver health benefits for a large fraction of the world’s population, while reducing the economic and environmental burden of the current fuel‐based lighting technologies.
