It looks correct because it says full spectrum daylight. It is the bulb that matters. I mean yes the correct fixture to fit the fluorecent bulb matters too. but we have to make sure the bulb is the same as th SAD lamps, it does not look like it comes with bulb?? I will re-read your post to see.
I have seen those shapes of bulbs before in tiny hydroponic tabletop “greenhouses” people use to grow kitchen herbs. I did not know they were the same? I guess the shape of the bulb may or may not matter?
That is a fluoresent bulb. Even regular shoplight fluoresents produce a wider range of light wavelength colors than led or halogen or incadescent ones.
my point - We need to find the name and specs of a bulb for a SAD lamp and compare it to the bulb that either comes with this lamp, or one that may fit it.
By specs I mean light intensity or brightness along with the kelvin rating and such other things.
But i think you are right about full spectrum from what i remember of the post.
