DESCRIPTION:Speakers: James Khennet  Aying (Cebu Technological University 
 )\nArtificial light at night increasingly obscures the stars\, contributes
  to skyglow and glare\, and diminishes opportunities for public engagement
  with the natural night sky. Although advanced lighting technologies can m
 itigate these effects\, their cost often limits adoption in many local com
 munities. This study evaluated a DIY Light Shielding Hood as an affordable
  intervention for improving outdoor lighting performance in urban and prov
 incial settings in Cebu\, Philippines. A mixed-methods experimental design
  was employed to compare lighting conditions before and after installation
  of the shielding hood. Measurements included upward light spill\, ground 
 illuminance\, visible star counts\, and observer-rated glare. Field testin
 g was conducted under comparable nighttime conditions in locations represe
 nting contrasting ambient-light environments. The intervention produced su
 bstantial improvements across all indicators. Upward light spill decreased
  by approximately 99% in both settings\, while ground-level illumination i
 ncreased through the redirection of previously wasted light. Visible star 
 counts increased by 110% in the provincial setting and 66.6% in the urban 
 setting. Observer-reported glare was also markedly reduced\, resulting in 
 improved visual comfort. Statistical analyses confirmed that these changes
  were highly significant (p \n\nhttps://indico.narit.or.th/event/238/contr
