I have purchased a few nightlights (over the last 6 months) that come
2 to a pack. They either use a 7 watt or a 4 watt bulb. Most of what I
have purchased are 7 watt units.
These come on when it gets dark in a room of course.
I have noticed after a few days of purchasing a new unit ( or a few
weeks ) that the unit stops working. The bulb is still good (I try in
antoher base). This occurs in more than one outlet in the house even
on a different circuit.
Now perhaps I am getting a surge but I would think I would notice this
in other ways in the house. Normal (2 year old) house with smoke,
carbon monoxide detectors, other lights, etc.. No other lights,
appliances are giving me any problems. No other bulbs are burning out
in regular lamps.
Perhaps these units just do not last long or at least the ones I have
tried from Home Depot or Eckerds. Usually Home Depot.
Silly I know, but perhaps someone has an idea on why the base burns
out and something else to try as an alternative. Not real fond of the
green flat night lights (need a little more light in some areas-for
when a elder relative comes to visit).
