Walked into a room and your friend left it at say, green at 3%? You want to make it nice and bright but can't be bothered reaching for your phone - there's a solution!
- Flick the wall switch off
- Flick the wall switch back on for about 1-2 seconds
- Flick the switch off again
- Flick the switch back on
Voila! You have a nice bright light to see by, all with what equates to a quick double flick of your light switch. Just make sure to give it that 1-2 seconds between flicks.
