LED lights come in all types, they go through model upgrades regularly too, although said to be designed for many many hours of usage, the truth is theyre anything but, the issue comes from all lights exhibit different light outputs in terms of light angle, colour rendering index, colour temperature and power intensity, it is almost impossible to find the exact same light of the make and model to suit so the closest available models thats currently available in the market is used for replacements, meaning that there will be subtle diffrences in how the replacements light/s would look compared to the rest/original set of lights.
