1.What are Full Cutoff vs. Semi-Cutoff Wall Pack lights respectively?


1.1 Full Cutoff Wall Packs lights means

"Full Cutoff" means that the light is affected by the shape of the casing, and the light is concentrated in the same area. This is called full cut-off.
Full Cutoff Wall Pack Lights are outdoor wall‑mounted LED fixtures designed with fully shielded optics that allow zero upward light emission.

1.2 Semi-Cutoff Wall Packs lights means

Semi-cutoff wall pack lights are a type of outdoor LED wall-mounted light fixture designed with partially shielded optics that directs most light downward and outward, while allowing a small amount of upward light emission.

2. Dark Sky Compliance requirements for LED outdoor lighting

Dark sky compliance refers to lighting standards designed to control light spill, reduce upward light emission, and lower light pollution. Key standards are set by the International Dark-Sky Association (IDA), while US local dark sky laws apply across states such as California and Texas.
Using non-compliant wall packs may result in municipal fines, neighbor complaints, and failure to pass commercial building inspections. A fixture’s cutoff design directly determines its light distribution pattern and dark sky eligibility.
