у монитора достаточно специфичный спектр свечения и светит он прямо в глаза, а у таких ламп спектр более широкий (не такой лютый пик на синем) и свет более рассеяный. Да и на фон тоже нормальное количество попадает.
это ваше подушка приняла форму запястья. Как следует из моей практики, правильный силикон под давлением проседает, но при снятии давления возвращается к исходной форме.

А можно про это подробнее? Что в мониторе, что в лампе стоят белые светодиоды. Откуда берется более широкий спектр у светодиодной лампы? Разве только, что субъективное ощущение сравнения более теплого света лампы с монитором, настроенным на холодные цвета.
