1. Heat dissipation
It is seldom mentioned in the product page if you are a constant some on-line shopping customer. As a reliable LED flood lights manufacturer,we remind you to pay attention to this factor. The fact is that the LED chips will be damaged if the junction temperature keeps incredibly high. A good LED flood lighting should have effective heat sink system transferring the heat from the internal structure to outside. Aluminum is a good conducting material to fabricate the heat dissipation system. In AIS, LED flood lamp is made of aluminum or the related alloy to make it long lifespan.
2. Power selection
The power of our exterior LED flood lights are ranged from 10W to 1000W. However, how many power should you choose? If you intend to use the lights for backyard, BBQ party or outdoor activities in your home, the lux level should be around 100.
How do you find the corresponding wattage? For example, if you have a 50 sq meter yard, the brightness required is 50 x 100 = 5000 lumens. For the LED having 130 lumens per watt, the power needed is 5000 / 130 = 38.5W. And hence 40W LED would be suitable. This value increases with your size of backyard as well as lux requirement.
If the need to do the vehicle repair work in your garage, you will need around 500 to 600 lux. Similarly, you may buy 200W LED floodlights for each 50 sq meter. It is not necessary to buy one single light. Instead, you can have 4 to 5 sets of 40W LED flood lamps putting around the ceiling to achieve better uniformity.
3. Waterproof
Water resistant is a vital feature for outdoor LED flood lights. To be able to work under rain or snow storm, the luminary should have at least IP65 ingress protection rating.
4. Energy saving
We always heard that doing LED replacement with halogen or metal halide lamps saves a certain percentage of energy. What is the truth? It is all depends on luminous efficiency of the LED flood lamps. For example, if a LED light has the specification of “120 lm/W”, it means 120 unit of brightness is emitted for each wattage power consumption.
Let’s do the quick calculation. If the 100W halogen bulbs has luminous efficiency of 20 lm/W, it produces 100 x 20 = 2000 lumens; however, if we use LED light, we also need 2000 / 120 = 20W. That means a 20W LED bulb and 100W halogen can produce the same brightness theoretically. So we can save (20W – 100W) / 100W x 100% = 80% energy.
Generally higher the lumens per watt (lm/W), higher the lighting efficiency and the price will be higher in normal circumstances.
5. Low maintenance solutions
Maintenance can be very challenging for seniors due to reduced physical ability, health issues or budget constraints. Eliminate the need for bulb changes by outfitting exteriors with LED flood lighting solutions. LED flood lamps are designed to last for decades – making them a great, low-maintenance solution for aging individuals who may be unwilling or unable to replace outside light fixtures.
6. Service life
Another reason to replace the conventional light to LED is the increased life span. According to the product description, the working lives of the LED flood lights can be 50000 to 80000 hours, which is 5 to 8 times of halogen and metal halide lights.
The lights having higher life span would always be your best choice because it is costly to buy the new lamps & install them, especially you are having the large-scale replacement. If you turn on the lights for 10 hours per day, LED runs 22 years. In reality, many customers complain that the metal halide or halogen lamps goes off easily, within 4-8 months use. Hence, switching to exterior LED flood lights save you a lot of time and money.
