It is not possible to accelerate electrons--or anything else--to the speed of light, much less to 1.5 times the speed of light.
Nominal operating voltages for a CRT range from a couple of thousand volts to a few tens of thousands of volts, depending on the application.
A light bulb is manufactured to operate on a specific voltage. The voltage can be a low as needed and the manufacturer will compute the size of the filament that is needed for a specific wattage. If you are referring to a threshold voltage then that is another question that needs to be asked.
A Scanning Electron Microscope, or SEM, is a type of electron microscope. Its light source is from a beam of high voltage electrons.
To answer this question the voltage of the bulb is needed.
by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.

The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
Electrons in a conduction band.
A basic electrical circuit needs a voltage supply (battery or household outlet), wiring to carry electrons to and from the voltage supply to the load, and a load (motor, light, heat element, stereo, blender, whatever).
Light is needed to excite electrons in the electron transport chain to commence photosynthesis.
The cutoff voltage depends on the maximum kinetic energy of the emitted electrons. The brighter the light the more photons released. which means more electrons released. each photon will release an electron with the same maximum kinetic energy whether the light is bright or dim. therefor the cutoff voltage remains the same if the brightness is increased
A Scanning Electron Microscope, or SEM, is a type of electron microscope. Its light source is from a beam of high voltage electrons.
To answer this question the voltage of the bulb is needed.
The following tools are needed to install a motion sensor light: 4-in1 screwdriver, voltage tester and a wire stripper. Also needed is a motion sensor light, elctricians tape and plastic.
Michael Faraday's made a light bulb with a platinum wire, he put it in a small glass globe, and attached it to a low voltage source. it glowed and produced light. Platinum is expensive. It only worked at low voltage. Others made lightbulbs. Edison decided a light bulb was a good idea but it needed to be made inexpensively. It needed to work at a higher voltage. The source of the electricity needed to be different from the place where the light bulb would be used. He looked for a material that could be made inexpensively and could last. It needed to be able to take higher voltage. He heated some thread until it turned to carbon. Then he made a vacuum inside a light bulb. He put the thread inside the bulb. It worked. He created a light bulb. It could be made inexpensively. It could work at a fairly high voltage.
