As soon as item arrived, I performed tests in order to define the right Wattage of this 30Watts COB Led. For my (good) surprise the item has shown 32.3Watts, what is slightly superior to what was stated. This is the reason why I have chosen a recognized and respectable brand for this item. For sure, the next step will be to add the proper heatsink but, at least, it has certainly passed on first tests.
