A simple light hack but one that helps Stefan save energy.
We have a dining room table light (not made by IKEA) which has 5 E14 fitting type bulbs. The original bulbs were 25W a piece, which adds up to 125W total.
Trying to reduce our energy usage I decided to replace with the 5W Sparsam CFL's. At first it didn't look too pretty.
The solution was simple: spray-paint them to a matching color and so the label text isn't visible anymore. The result: energy usage dropped from 125W to 25W. On the last picture you can see lights 1, 2 and 5 have been replaced with the Sparsam bulbs, lights 3 and 4 are original (for comparison purposes).
