In order to prove that its light bulbs are money-saving bulbs even though they are more expensive initially, the Megaman company came up with the Light Bulb Calendar.
This large time tracker is a beautiful piece of home furniture design, even though it is only currently found within BoConcept store locations. Each day on the calendar has a different socket so that the bulb can be transferred from one day to the next, marking time while also proving that the light bulb can be turned on day and night for an entire year without burning out.
Even though regular bulbs seem cheaper from the get-go, the real money-saving bulbs are the energy-efficient ones like those by Megaman, which last longer and save money in the long run.
