**lumens**/watt so a 100

**street light**would be1800

**lumens**, a 400 watt bulb would be around 72,000

**lumens**using that figure.

In respect to this, how many lumens is the average street light?

2004. "The **lamps** used in streetlights vary inboth size and consumption (typically between 35 and 250 Watts)depending upon whether they are lighting a residential area, mainroad or a town centre." "It is generally assumed that the**average** wattage of a **streetlight** is about 80 watts."Outdoor Lighting Handbook.

Also Know, how many lumens do you need to light up a room?

To determine the needed **lumens**, **you willneed** to multiply your **room** square footage by your**room** foot-candle requirement. For example, a 100 square footliving **room**, which needs 10-20 foot-candles, **willneed** 1,000-2,000 **lumens**. A 100 square foot dining**room**, which needs 30-40 foot-candles, **will need**3,000-4,000 **lumens**.

The total **lumens lighting** required are equal to1,800 square feet times 30 foot candles per square foot, or 54,000**lumens**. Calculate **how many lights** you need.Incandescent bulbs and fluorescent **lights** have **lumen**ratings on their packaging. Divide the **lumen** rating into thetotal **lumens** you need.
