3. Motion Sensor

1. Wattage Choice
How do you choose the most suitable wattage for your security lights?
According to the area you wish to light, we have some suggestions.
For garden and backyard lighting, our suggestions are: (depends on your need for brightness)

So, how are these suggestions made? We base it on science and calculation:
Lumens needed = (illuminance Target * Area) / (LLT *CU)
LLT = 0.75
CU = 0.7 for Outdoor LED flood lights

If you are interested in the formula, feel free to contact us.

Different applications, however, will have a different standard applied. Take parking lots for example, which need more light. The illumination requirements are different still for intersections and entrances.

By the way, many LED flood lights provide fake or inflated wattage/brightness information. So, please buy from a trusted brand. Otherwise, your area may not look as bright as you wish.

2. Colour
Next we look at how to choose the light colour.
Daylight white is the most popular choice for outdoor lighting.
If you love a more relaxed environment, though, you can choose warm white.
RGB is a good choice for special purposes. For example, party lighting, mood lighting, and other special cases work well with RGB lights.

3. Motion sensor
Do you need LED security lights with motion sensor?
If you want to save on your electricity bill and have a long-lasting product, the answer is yes.
If you want to save the effort of turning your lights on and off every day, the answer is again yes.
However, the price for this is usually at least 30% higher, so you’ll need to factor that into your budget.

So, follow above 3 steps and you can buy like an expert.
