Photoresistors also known as light dependent resistor (LDR) are used to increase light intensity by decreasing resistance. This is applied to camera lights, street lights, solar street lamps.
Parallel. One light burning out does not stop all current flow to the other lights.
The solar street lights in which all the components are integrated into one single unit are called all in one solar street lights. Traditional all in one solar street lights use SLA (sealed lead-acid battery) but their modern counterparts prefer lithium-ion or LiFePO4 batteries. All in one solar street lights with motion sensors are energy efficient and priced reasonably. To Know More : Tapetum Solar Street Light
"Lights" is plural. The singular is "light." As a noun, the word "light" can refer to something you turn on to brighten a room, or it can refer to brightness in the sky. Here is an example of the plural: When we had a hurricane last year, the lights went out everywhere on our street. The singular is like this: Please turn on the front porch light so that we can see where we are going.
Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.
According to Enertia Engineering Ltd., a Enertia Solar Street Light costs 75$, while a traditional solar street light costs 170$. Compared to these solar lights, a regular street light costs 550$.
Usualy nigh lights or cretin street lights :)

light pollution is mainly caused by the glare of the city street lights. There is no way to prevent this from happening due to the fact that you can't stop the reflection of the lights on the street from reflecting back to the sky.
Street Lights stay on in the night as they have a light detection unit on the top, if the sensor falls under shadow it turns on.
Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not in the sky for an extended period of time.
1. Turn the lights off (not good) 2. Use dim lights (not very good) 3. Design street lights properly so they send their light down on to the street and not up into the sky (best).
Street lights date back thousands of years. As early as the 4th century Antioch had street lights. Street lights were also used in the 9-10 centuries by the Arab Empire. In 1417 in London Henry Bastien ordered lanterns to be hung on winter nights and by 1792 William Murdoch had installed gas lights in London. In the United States Ben Franklin helped with street lights and by 1816 Baltimore was the first city to have street lights.

Indirect light would be larger than direct light, because indirect light is from an angle, and it is usually dimmer.
Street lights are very important. They automatically turn on when it gets dark outside, providing a small amount of light for people who go out at night. They help drivers see things out of range of their car's headlights and give pedestrians light to see by.
