Comparing Incandescent and LED Lamps

Comparing Incandescent and LED Lamps | Science Fair Projects | STEM Projects
We're comparing incandescent and LED lamps to see which one is brighter and uses less power. We'll measure the brightness of each type of lamp and see which one requires less power to produce the same level of brightness.


The hypothesis is that the LED lamp will require less power to produce the same level of brightness as an incandescent lamp.

Method & Materials

You will wire cables and plugs to the incandescent and LED lamp sockets, measure the brightness of each lamp using a lux meter, and record the measurements in a table.
You will need a 60 watt incandescent light bulb, a socket for the incandescent lamp, LED bulbs of several wattage ratings, a socket for the LED bulb, electric cables, 3-pin plugs, a lux meter, and a ruler.


The results showed that the 60W incandescent lamp provided the same brightness as a 7.5W LED lamp, proving that LED lamps provide the same brightness at a lower wattage and power consumption compared to the incandescent lamps.

Why do this project?

This science project is interesting because it compares two types of light bulbs and shows how LED lamps can provide the same brightness as an incandescent lamp but with less power.

Also Consider

Variations of this experiment could include comparing a fluorescent light with LED lamps, or comparing the brightness of the LED lamp and incandescent lamp at different distances from the light source.
