The effects of illuminance level and lamp type were investigated for crime prevention in Thai pedestrian walkways aimed to examine the effects of illuminance on perceived safety, pedestrian behaviour, and criminal identification as part of crime prevention. Laboratory tests were carried out at the Faculty of Architecture, Kasetsart University. Five levels of illuminance: 10, 20, 50, 100, and 200 lux, and the types of lamps—HPS, LED Daylight and LED Warm White were investigated. Experimental tests were performed using a 3D model with DIALux simulation. Results showed that each lamp type required a different illuminance to optimize crime prevention. The HPS lamp with an illuminance of 200 lux was found to be the most suitable level for perceived safety, while 10 lux was suitable for pedestrian behaviour and 10 lux was suitable for criminal identification. For the LED Daylight lamp, the illuminance of 200 lux was the most appropriate level for perceived safety, while 20 lux was suitable for pedestrian behaviour and 10-20 lux was enough for criminal identification. For the LED Warm-white lamp, the illuminance of 10 lux was the most appropriate level for perceived safety, with 20 lux for pedestrian behaviour, and 10-20 lux for criminal identification.
