-- increase the voltage across its terminals
-- coat the inside with a brighter phosphor
-- clean the outside of it
-- mount a flat mirror or parabolic half-shell behind it
change the battery
The Shorter the wire the brighter the bulb ! Because if it is short then it get brighter and the more batterie the brighter the bulb ! Or the lower voltage the brighter the bulb !
you can make it brighter by adding another battery/cell
it explodes
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
The LED bulb is brighter than the incandescent bulb.
Wipe it with cloth I guess?
Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.
shut up you nerd
Increasing the amount of electrical current flowing through the bulb's filament will make it shine brighter. Additionally, using a higher wattage bulb or a bulb with a higher lumen output will also produce a brighter light.
To make light bulbs glow brighter, you can increase the voltage supply to the bulb. This will cause more current to flow through the filament, resulting in a brighter glow. Be cautious not to exceed the recommended voltage rating of the bulb, as this can lead to overheating and damage.
Depending on the length of the wire difference between the shot and long wire, in technical fact the bulb would be brighter if a shorter wire was used, but not that much brighter. Energy is used up as it travels along wires.
