For those who are hard-wiring their bedside reading lights directly into the walls, consider the addition of dimmer switches. It isn't uncommon for the lighting in bedrooms to either be too harsh or too dark. Therefore, dimmer switches allow for optimal lighting control. That way, the task lighting at your bedside will always be set at a comfortable brightness. The addition of the dimmer switch also prevents the room from becoming too jarring when the lights go on after you’ve been asleep. The most significant challenge regarding these switches is selecting which kind of light bulb to use. The recommendation is to follow the instructions that come with the bedside reading lights or with the dimmer switch.
