You may hear more and more news about LED recently. LED (light-emitting-diode) is a semiconductor diode that emits light. It contains solid state lighting technology. There are so many kinds of light sources for flood lights, such as metal halide, high pressure sodium, halogen, mercury vapor and so on. Why have LED become more and more popular? You can find reasons in this article.
1. Higher Efficiency
Now, maintain efficiency of LED flood lights can be over 85 lm/w. It’s about 5 times than halogen, so it can save over 80% energy comparing with halogen lamps.
Because of color temperature and color rendering index, they can save 50%-70% energy comparing with high pressure sodium floodlights.
2. Eco-friendly
LED flood lights do not contain UV, IR, Lead or mercury. It can be absolutely eco-friendly. Besides, the heat is less.
high pressure sodium, metal halide or mercury lamps can not be eco-friendly as LED lamps.
3. Long Lifespan
In theory, lifespan of LED is over 50,000 hours. It’s about 5 times than metal halide and mercury lamps. It’s also 8 times than halogen.
So, it saves maintain and product cost
4. Color Is Easy to Control
LED can emit full range of color, so LED flood lights can be full range of color.
5. Perfect Combination With Solar Power
Because LED floodlights save energy, cost of solar power is low. So, in many project, we choose solar power for LED lighting.
So, you know LED flood lights have some many advantages. Energy saving, long lifespan and eco-friendly are popular all over the world. So, it become more and
