DaasYochid,
I disagree. You wouldn’t have a lamp on if you couldn’t cover it, so the net gain is having light when you need it.
Yes, that is correct, and the way I said it incorrect. In my case, the light usually starts out uncovered (e.g., for reading) and is then closed for sleep, which is why I perceived that as the benefit. But if there were no Shabbos lamp, I’d have no light on in the room at all, so the true benefit is the light.
You may perceive the marketing as treating Shabbos as an inconvenience, and maybe that’s indeed the (very distasteful) marketing strategy,
Just out of curiosity, if you are familiar with the marketing that has been used, do you disagree that it treated Shabbos as an inconvenience?
but the product itself can just as easily be used “to bring us additional delight and comfort on Shabbos”.
In what way can that be so, other than providing the “delight and comfort” that only a melacha would accomplish?
