I am having problems with my basement lighting. How many shoplights per on/off switch is acceptable?
Here's the history of my lighting problem. Sorry if it's so long:
In 1976 we had shoplights installed in our basement. Two in the laundryroom, one in a storage room/office. Each room has their own switch.
The main area of the basement has four shoplights (set of two in each fixture). I'm not sure of the watts. Originally, these were controlled by a dimmer switch. However ten or more years later, the lights began to flicker. At which time an electrician told us that dimmer switches are not the best to have and replaced that switch with a regular, nondimmer, switch. The lights worked fine until 2004. At this time, another electrician said that the switch was lose and needed to be tightened. The lights worked fine until 2009.
Gradually each light dimmed or would not work at all. This led me to believe that they needed to be replaced. I purchased some new replacement lights -- and when we went to install them -- lo and behold -- all of the lights worked. The guy who was helping me said that I may have problems with the ballusts (sp?).
A week later, the lights were acted up again. Some light while others didn't. Some of those that weren't working, came kicked on later.
I've talked to various people what could be wrong -- and still have to find an electrician that can squeeze me into his schedule. All have stated that it could be the ballusts, in which case new fixtures would be more affordable than just replacing individual ballusts; it could be the shoplights themselve, or it could be that there are too many lights for the one switch to handle. (Again there are four, with two lights (48-inch) in each. There is one switch at the bottom of the stairs and another at the top. (The one at the top also houses a switch to the garage; and the switch at the bottom houses the switch to main basement lights that are acting up and one that controls the shoplights in laundryroom next to the main area.
One person suggested that the air in the basement may be too damp at times, and when the humidity/dampness decreases, it causes the lights to work properly. There are registers to the basement, but we don't allow the basement to be heated. I run the dehumidifier 24/7. During the summer it has to be emptied three or more times a week (bin is half full). During the winter, I hardly ever have to empty the dehumidifier.
Any opinions or suggestions will be appreciated!
