e.g. McMaster-Carr with a 10 year in-home repair warranty.
And you can still offer discounts via other lower price channels.
The vendor travels to the house and repairs it? One warranty claim could wipe out a startup.
I love the idea of high quality lighting inside especially for my Chicago place.
The one you linked is a stand alone lamp and they seem to focus on red light which I don’t quite understand. Red light (or very low CCTs) is used for skin therapy but typically requires direct exposure to the skin because irradiance levels need to be super high for that - from my understanding you wouldn’t have any benefit from a red lamp even at 750w. But blue light does can have lots of health benefits at low levels (search for ipRGCs).
