Flexible LED strips are widely used as decorative lighting. You may find them in many areas, such as car and motorcycle decorative lighting, architectural decorative lighting, archway lighting, hallway lighting, stairway lighting, cove lighting and so on. They are easy to install and cut every 5-10cm. Besides, LED is energy saving, eco-friendly and long lifespan. Thereby LED strips also have these features. The lifespan is over 50,000 hours.

　　Main features:
　　1. LED. The light sources are usually SMD LED. 3528 SMD LED and 5050 SMD LED. The brightness of each types of LED is different. 5050 SMD LED is brighter than 3528 SMD LED. Usually, RGB LED strips are made by 5050 SMD LED.
2. Colors. The color can be white, warm white, red, blue, green, pink, RGB and so on. The price is different in different colors.
3. Quantity of LED. Usually the quantity of LED is 15PCS, 24PCS or 30PCS per 50cm. It also influences the brightness.
4. Length. In most of case, the length is 50cm. There are also 30cm, 60cm and 80cm length. However, you do not need to worry about it. Usually, every LED strip can be cut every 3 LED. That's 5-10 cm.
5. Waterproof or non-waterproof. Waterproof or non-waterproof are both available.
6. Working Voltage. Usually working voltage is 12V DC.
7. Power Consumption. Usually power consumption is from 2.4W to 3.6W every 50cm.
　　The above features are main factors. For more features, you may contact your suppliers.

　　How to Choose right LED strips in your project
After we know the above 7 main features, it's easy to choose right products in you project. You just need to tell your supplier the following requirements:

1. Colors. If you need RGB colors, you need a controller to control the colors.
2. Brightness(Luminous Intensity, Flux or other in your descriptions )
3. Waterproof or non-waterproof. If you need waterproof products, IP rating is also a factor.
4. Length. If you a very long strip in your project, you need a amplifier to keep the effect.
5. Input voltage. Usually you need a transformer to transform the voltage.
The above 5 factors are important to both your project and price. You may take more requirements in your project into consideration.
