LED Flood Lights sold with low price all use cheap chips, this will greatly decrease the overall usage. The first reason is cheap chips decays faster, which means the brightness of the whole light would be reduced a lot; Secondly, power resource is an important component and plays an important role in LED flood light usage. Cheap power resources would have the problems of glittering light, large reduce in brightness and frequent replacement needed after a period of time (usually 1-2 years), while good power resource can be used for at least 3 years and some can even be used as normal for 5 years/50,000 hours. Last but least, the radiator and protection grade of LED flood light also need to be considered. Normally the temperature shall not exceed 75℃ after long time usage, while the suggested protection grade is above IP65 in outdoors.
