I don't like Jeff Bezos as an individual, but I do like Amazon as a service. It IS efficient, saves me a lot of driving trips that otherwise would be dumping that much more CO2 into the air, and carries a large number of vendors so I can be very specific in finding something that meets my needs, and if something goes wrong they are very quick and easy to make it right.

For example, I tend to suffer a bit from what is known as Seasonal Affective Disorder, basically a depression that comes on in the winter when the days are shorter, only for me it's not really so much emotion but physical, I sleep much longer hours, generally have less energy and motivation, and one of the LED bulbs in my office was already failing so I thought I will order some very bright bulbs and with a slightly bluer color to help me get through the winter better. Old lights were about 2800k color temperature and had kind of an orangy pink color, I really wanted more red in them but instead got a lot of orange. Ok, so this time I ordered some 4000k 2700 lumen bulbs.

Ordered a package of four from Amazon, two days later they arrived. Put the first three into service, excellent, really nice neutral white light and no flicker and brighter, I instantly felt an uplift in my energy level. But when I installed the fourth, disappointment, it was dim, produced an ugly blue-green light, and and flickered horribly.

Called Amazon, five minutes later a replacement is on the way. I'll probably take existing bulb apart to see what is wrong, but I kind of suspect the LEDs themselves did not get the proper phosphor coating because nothing else could really explain the aweful blue-green color, but also a defective ballast would cause the flicker. The ballast I might be able to repair but can't do much to fix the leds, but I can find some other use for them.
