A pencil has nothing to do with the brightness of a light bulb.
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
The brightness of a bulb is directly related to the amount of power it consumes. The higher the wattage of the bulb, the brighter it will be. Additionally, factors like the type of bulb (incandescent, LED, fluorescent) and the age of the bulb can also affect its brightness.
The best candelabra base LED bulb with a 60W equivalent brightness is the Philips LED Dimmable B12 Candelabra Base Bulb.
Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts. The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.

The pencil lead does not have a significant effect on the brightness of the bulb in a circuit because it does not conduct electricity efficiently. In order for the bulb to light up brightly, the circuit needs an efficient conductor such as a metal wire to allow the current to flow easily and light up the bulb.
The brightness of the bulb would decrease as the alligator clip moved along the pencil lead. This is because the resistance in the circuit would increase as the clip moves farther from the battery source, resulting in less current flow and therefore less brightness in the bulb.

The brightness of a bulb would not change if you added a second bulb in parallel with the first.Unless, of course, the increased current exceeded the power supply's capacity causing a reduction in voltage.
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
If smaller means less power for the same voltage, then a smaller bulb would result in less brightness. If smaller means less voltage for the same power, then a smaller builb would result in more brightness.
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
The relationship between voltage and brightness of a bulb is directly proportional. As voltage increases, the brightness of the bulb increases because higher voltage provides more energy for the bulb to emit light. Conversely, decreasing voltage reduces the brightness of the bulb.
A 9W LED bulb is roughly equivalent in brightness to a 60W incandescent bulb.
The brightness of three bulb would be mare than one
To increase the brightness of a bulb, you can use a bulb with a higher wattage, as higher wattage typically produces more light. Alternatively, you could use a dimmer switch to adjust the brightness if the bulb is compatible. Lastly, ensure that the bulb is clean and free from obstructions, as dirt or dust can diminish its brightness.
