There are quite a few websites online that you can buy LED bulbs. The problem is "how do you compare one bulb to another?" A quick way to do is to calculate the lumens/watt, or in laymans terms, the total amount of light you get for the amount of electricity you put in. This is done by simply dividing the bulbs wattage by the stated number of lumens.

Anything over 50 lumens/watt is good at the moment. 75 lumens/watt is very good while 100 lumens/watt is excellent. We will be discussing the concept of lumens in a more detailed article in the near future titled: Lumens why you cant use them to compare LEDs to traditional bulbs.

One thing to keep in mind: A halogen flood bulb is more efficient than an incandescent flood and usually costs a little more. Typically for a halogen you get about 1.5x more light for the same wattage. i.e. a 20W halogen bulb gives about the same amount of light as a 30-35W incandescent flood. You can tell if its an incandescent or halogen by reading the packaging of the bulb.

Consider the cost savings and four benefits：

1. Costs - LEDs cost more initially, and there is no doubt that they save you a lot of money in the long run because they last longer and use less energy. Money savings is from using 80% less energy and not having to buy about 25 traditional flood light bulbs. Depending on your state, savings and time for the bulb to pay for itself can vary.

Over 50,000 hours for a typical 7W LED Flood Light replacement bulb that replaces a 50W Incandescent Flood at 8 hours usage per day

we are using to traditional incandescent and fluorescent lighting many years, now why did us choose LED lighting?

what is it reason to choose LED lighting for us? Energy saving, environmental protection, longer lifespan, these should be reasons why the preferred LED lighting, and LED lighting is easy to install, low maintenance, can directly replace incandescent lamps in use and energy-saving lamps, the same power products, energy-saving effect is obvious, Aohai ​​LED lamps not only has this advantages, we are have advantages for other manufacturers.

Traditional lamps are directly connected to the 220V AC, while the LED lighting power supply needs to alternating current into direct current, the constant pressure mode of operation: LED power supply directly affects the efficiency of light-emitting efficiency
