WHY DO MY ENERGY SAVING LIGHTBULBS FLICKER ON AND OFF EVEN WHEN I TURN THEM OFF?

Mine will pulsate at night because there’s an LED night light in the adjoining bathroom that cycles through various colours. CFL lightbulbs are fluorescent light bulbs which means that they have a coating of fluorescent paint on the inside of the bulbs to absorb the UV light produced by the plasma in the tube and emit visible light but this means that they can absorb faint energy from a lot of other wavelengths from a lot of other sources and emit them in the visible spectrums and thereby appear to glow or flicker even when off. You can use a bulb to detect a radiation leak from a microwave because of this. In the 70′s people would attach small neon bulbs which work on similar principles to the top of their CB radio antennas so that the antennas would light up when they talk. I’m surprised that there hasn’t been fluorescent customization skins for cell phones that flicker.
