Very nice lamp, I like it There is only one thing that puzzles and worries me. You designed a lamp (IP67 rated I see) with a metal housing that additionally works close to water, and you provide a cheapest AC power cord without earth-grounding? After all, this is a basic safety rule . And please do not write to me that the power supply is well insulated because you are not able to predict all the events that may happen.
The grounded power cord should be a standard component of this lamp. Not on the principle that if someone asks, will get it. A great way out, advise the customer that should modify the home electrical system by adding RDC… Not every customer has to be an electrician and know how to do this. You pay great attention to the quality of the lamps (components used, modifications, cooling) and you neglect the basic safety rules .
RDC it is the main component of any home electrical system. In USA it is 5mA. Ordinary it is 30mA. In Belarus or Russia or Ukraine they do not need ground wire, because they do not have ground contact (or just ground contact in socket without wire) in most situations.
I love the Led lights and all the trend that is going around. However, I feel closer to the smart bulbs. For example, using a let all you get is different colors, but sometimes it might look unesthetic. However, when I bought my Vont bulbs, I could do much more.
