Why Solar flood lights?


Solar powered motion activated LED floodlights are fast becoming the norm in garden and other outdoor environment lighting. These lights are cheap, economical, easy to use and don't need clumpy wires to connect them to electricity outlet and the best part is that they don't use electricity at all or rather you don't need to supply it and the light powers itself from that solar panel. These wonderful lights are a bit pricier than regular flood lights but they use the LED technology that allows you to power them with only the solar power and it also provides a very long lifespan. So in the long run you will definitely get you money back and will continue saving bucks for the rest of that fixtures life and that can be even 10 year because LED diodes have 50000 hour rated life span and often work longer than that!
All this is good and understandable but are there any disadvantages that could repel potential customers? Actually there are a few but they are minor ones:
Cost -  As I mentioned earlier Solar powered flood lights are costly and they can be twice as expensive to buy if you want to match them to the light output of other flood lights.
Light Intensity -  LED diodes are not powerful and you need a lot of them to cover a wider area but that also increases the risk of heat damage so most LED powered flood light are made with low amount of diodes and don't produce very intense light. This can be a issue if you want to illuminate a wide area but you can always use multiple light sources!
Light Spread -  LED diodes usually have a very narrow span and they shine light only in front of them but with things like light spread increasing flood light covers manufacturers have managed to get around this problem.
They need a full day of sunlight to recharge - because usually those solar powers are quite small they need to be in a direct sunlight to generate the maximum amount of electricity and with that maximum output they need almost full day of sun to fully recharge completely drained batteries. This also means that if you get a cloudy day you won't fully recharge those batteries and you will not be able to produce light as long as the total battery capacity is.  
Light build quality problems - These solar LED flood lights are usually made by companies that are not that experienced with consumer products and because there are so many fragile and delicate parts some light will not work properly after only a few month use. But this problem can be overcome by purchasing only good quality lights from reputable sellers.

These are all the major disadvantages and they are not nearly as bad as those advantages are good so in my mind if you have the option to choose from a solar powered flood light or a regular one then don't hesitate and buy the solar one.

Advantages of Solar LED flood lights

Solar led flood lights are very popular among people when it comes to illuminating any large area. Flood lights are constructed to provide enough brightness to illuminate such large areas like sports fields, stadiums, theater stages and others. Regular people uses Flood lights at their homes, gardens, pools, backyards, patios, sheds, garages, front doors and many other places. If you are interested in what advantages solar LED flood lights have over other light sources, read this article and comparison with other popular flood light bulbs.

Primary pluses that LED flood lights have over other flood light sources are:

  1. Long lifetime -LED light have much longer lifetime than incandescent and fluorescent light bulbs. They can last up to 40 000 hours and even more. One LED diode can work for 20 years and  that is a lot compared to other bulbs that can not even work 5 years before they worn out. This is the main advantage that LED diode has over other light bulbs, and makes it really a good choice for flood lights, because it needs to work for long period of time without maintenance. Because flood lights are used to illuminate large area, they have many LED diodes in one light and if they would start to break after one year it would be hard and expensive to maintain the light and there would not be any purpose of using these bulbs.
  2. Durability - LED lights are much more durable than other light bulbs. It is hard to break a led diode in opposite to incandescent or CFL bulbs. This means that they are much more durable and safer to use. This advantages is useful when light is used outdoors. Solar Flood lights are mainly used outdoors and they need to be weather resistant and durable to stand any weather conditions. LED diodes are great to stand different shocks and much more difficult weather conditions.
  3. Brightness - LED flood lights are brighter than other flood lights. With same power they can produce significantly brighter light. This is another LED light bonus. If used outdoors at night, this option is good to use as a security light for your commercial building, residential area or other applications. Also bright LED lights are useful as decoration lights for your home, garden or backyard areas.
  4. Efficiency - As we know LED flood lights are brighter than other light sources. Solar LED flood lights are also much more efficient. If used together with solar panel they use only solar energy and as we know, solar energy is free to use for everyone, so Solar LED flood lights are much cheaper than regular flood lights. Together with energy efficient LED diodes, they make the best lighting source for anyone, who likes to save money on electricity bills. After buying a solar LED flood light there will be practically no additional costs for this light afterwards.
  5. Temperature resistance - Solar LED flood lights are also more temperature resistant than other competing light sources. They can operate with significant loss of energy in a lot colder temperatures. This makes it very useful at cold winters with lots of snow and ice. If you are living in area, where temperatures in winters are getting low and weather is cold and freezing, you certainly need to get a LED flood light as your outdoor floodlight.
  6. Safe for environment - LEDs are also safe for environment. They do not contain any toxic chemicals like mercury. This means that they are much more environment friendlier and cannot harm people in any way. In opposite, CFL lights contain mercury, which is toxic substance and is very dangerous for human and nature.
  7. Cheap to maintain - solar LED flood lights are much cheaper to maintain. They do not need a replacement for bulbs so often, probably for 20 or more years. If used together with solar panel, you do not need any wiring and can put the flood light anywhere you like. Solar flood lights can work even in places, where any other electrical power source is not near. When light is set up, afterwards costs will be much less expensive than they would be for other flood lights.
  8. Turns on quickly - LED lights turns on very quickly in nanoseconds and can be turned on and off without any lost of quality and lifetime. This is great advantage compared to other lights, tad tend to worn out and shorten their lifetime, if they are repeatedly turned on and off. This also improve quality that LED lights can offer for people. With all these advantages that LED lights have over other flood light bulbs, they are considered to be the best flood lights avaliable at the moment.
