Solar Lamp Post Lights



Solar lamp post lights are all-in-one integral solar outdoor illumination solutions. The solar post light is a low cost outdoor lighting product. Among its advantages are elegance, energy efficiency and ease of use.

An outdoor elegance

Greek and Romans used lampposts to protect pedestrians from street obstacles and to steer robbers away from the innocent citizens. Modern kerosene street lights appeared first in Europe, probably around 1853. It took another 25 years for electric post lights to appear in modern cities. In the old days, a lamplighter was going from one post to another to light up the lamps. Modern lamps are equipped with a built in light-sensitive sensor that turns them on before dark and turned them off after sunrise.

Recently, lamp post lights are popular as outdoor illumination for homes. The modern designs are elegant; they beautify the garden and backyard during daylight and provide enhanced safety and security during the dark hours of night. With the advent of photovoltaic technology, solar lamp post lights are in the mainstream of modern gardens, front door and patios lighting solutions. They come in a variety of styles and can be mounted on posts or to be wall mounted.

Energy Efficiency

The energy efficiency of solar post light is achieved by using LED (Light Emitting Diodes) bulbs. LED bulbs operate on very low DC voltage and provide the most luminance (light) for the invested electric current. LED voltage rating is compatible with the low voltage of AA batteries, and with the voltage of the solar electric panel. They enjoy very long life (over 10,000 hours) and come in a variety of colors.

Ease of Use

A typical solar lamp post lights include in one neat assembly everything that is needed for an autonomous operation and it doesn’t need to be connected to any of the residential power outlets. The assembly includes 6 or more LED bulbs, 4 or more rechargeable AA lithium batteries, and a small solar panel that covers seamlessly the top of the assembly, a photosensitive sensor that turns the light on just before dark and turns the light off just after sunrise. In some models, there is also an infrared sensor that detects the presence of people, and lighting is turned on only when people are around. In essence, nothing else is expected from the homeowner, it is an “install and forget” piece of equipment.

Summary of Advantages

The solar lamppost is autonomous, it beautify the outdoor over day and night, it enhance safety and security and it comes at affordable prices.

Cost

Cost in online shops, such as Amazon and Nextag as well as hardware stores can range between $100 and $400. It depends on style, mounting options and reputation of the manufacturer.

Disadvantages and Limitations

Attractive as they are, there are some limitations that need to be considered:

  • Rechargeable lithium batteries has a limited number of discharge/recharge cycles, therefore it is expected that the batteries will be replaced more frequently than the LED bulbs.

  • A typical lamppost specify that after 6 hours of recharge during daylight by the solar panel, there are 10 guaranteed operation hours after dark. This doesn’t leave any margin during the winter where there are fewer hours of sun and longer hours of dark

  • Lamp post works in harsh conditions, make sure the one you buy can survive these environmental tough conditions, will stay mechanically sound and will maintain its good appearance
