What are the standards for street lighting

Foot candles are basically a way to measure how much light hits a surface. When it comes to lighting up roads and parking lots, the right foot candle levels can vary based on a few things like traffic speed, how many pedestrians are around, and the size of the area. Here’s a quick rundown of what’s generally recommended:

1. Roadway Lighting: For roads where people drive slowly (20 mph or less), aim for at least 0.6 foot candles and up to 3.0 foot candles. For faster roads (30 mph or more), you’ll want between 1.5 and 6.0 foot candles.
2. Pedestrian Lighting: When it comes to areas where people are walking, go for a minimum of 1.0 foot candles and a maximum of 2.5 foot candles.
3. Parking Lot Lighting: In parking lots, the sweet spot is usually between 0.5 and 5.0 foot candles.

Remember, these are just general suggestions. The actual lighting needs can differ based on the specific conditions of your site. If you want to get it just right, a lighting audit can help figure out the best foot candle levels for your particular situation.
