Not sure if it's time to get an electrician or you guys have some advice fo
r me. I bought a new home and the coach lights by the porch work fine, but
the there's four different flood lights pointing up at the front of the ho
me. When I turn these lights on, some will come on, then maybe another one
will come on, then one will go off... Most often 3 out of four will come
on, but it's not consistent which ones.
They have big bulbs in these things. Maybe I should replace them with LEDs
sometime, but I'm wondering if I get out there and replace them I'll have
just spent a bunch of money on LEDs that don't all work either.
The lights look like they have really big incandescent bulbs in them. They
're all glass and screw in like a regular, standard, indoor light bulb. I
tried unscrewing them and screwing them back in, but that didn't do anythin

Remove a bulb to see if there is writing on it to determine the type of
bulb. Or if you can see a label on the fixture to determine the type of
fixture. If it's a metal halide or high/low pressure sodium fixture,
that would explain the off and on, which would most likely be the bulb.
If it is that type of fixture, do not buy LEDs and simply screw them in.
You can't screw in just any bulb in those type of fixtures. It would
require a direct 120 voltage feed.
Good point but I'd guess that this is a wiring hack job done by the previous
owner or his drunken jack-leg handyman using inexpensive devices purchased at
McLowesDepotBigBoxSuperMartHomeCenterOutlet...which explains why it's fubar.
After a few years even professionally installed sodium vapour lamps
purchased from first-line electrical distributors DO fail. About 3 of
the original 12 exterior floods at a 6 year old high end office
building are still functional. I've changed several of them - have

Not sure why you see frequent failures like that. Maybe your environment?
Our bulbs go on at dusk, off at dawn and last about 22,000 hours.
Winter lows are typically 20F and summer highs of 90F with lots of humidity.
Also, outdoor wire-nutted connections should be coated with appropriate grease
and oriented in the j-box so any water runs off instead of into the nut. (Think
upside-down coffee cup.)
Never had a problem with the wire-nutted connections. The bulb fails,
and if not replaced almost immediately, the ballast dies. Outdoor ,
mounted to steel "rail" around the front of the building, poiting up
to wall and signage above, or mounted to top of brick/stone wall
pointing down on wall-mounted signage -all mounting as per
manufacturer's specifications. Winter lows a bit lower, highs about
the same - same humidity. East facing walls , so not exposed to

If a transformer goes, I wouldn't waste time replacing it when it can be
eliminated and direct wired for a LED bulb.
We gave up before LED bulbs were available - still hard to get in

dissappear completely - and be replaced with purpose designed LED
At the plant where I work 2 afternoons a week, they replaced all the
parking lot lights with that kind of LED unit - and also replaced all
the vapour lamps in the factory. The office lights are also being
replaced during a renovation that has just started.

Find one new bulb that you know works and find out if it's a bulb
problem or something else? Take one of these bulbs, try it in
another socket, verify the bulb is good and then try it in the
In addition to the advice from others, also look to see if any of the
lights have an individual photocell control.
Lights with a ballast may have a warm-up time before they come on. If
they also have a photocell control, each could have a different
sensitivity to light.
