I got a sensor light with a 2 bulb fixture. The light is really
annoying. It claims that if I shut it off and back on in 5 seconds or
less, it will remain on. Well, that dont work. When I am working
outside I want this light to remain on.

I only use one of the 2 bulbs to save energy. I plugged the other one
with a dead bulb. My idea is to remove the wires going to the second
light, where they attach to the sensor, and wire that socket directly
to the power line with a separate switch. In other words, the sensor
will control one bulb, while the other bulb will be connected to a
switch only. That way I can leave the second light turned on as long
as I want.

Is this legal according to the code?

Thanks

Nec requires you to use and install equipment as per manufacturers
directions, so technically it probably wouldn't meet code. I wouldn't
hesitate to do it anyway, but it would probably be more efficient and cost
effective to just buy a properly working sensor

I have couple of them you could switch the light on with just a fast flick
of the switch. I have a bunch of those 120V motion sensor lights from
various manufactures on various properties. In time, perhaps temperature
drift in the electronic circuit, non of them work - comes on when you don't
need it and off when you do. The only sensors that work are on my solar
flood lights. I'm switching to fluorescent flood lights with just the night
sensor so it would stay on when I need it.

In my part of Texas, if anyone mentions 'code' we immediately shoot
them dead. So not many people mention the word.

Hi,
Those who love code is the ones who don't know anything. LOL!

Hi,
Those things have minimum load to work properly. Try with two 60W bulbs
and see. Mine has two 25W bulbs and I found out that's the minimum load
it needs.

Control circuit should be independent of load, sounds like a poor design.
Would be interesting to see a schematic of this circuit.

According to ** Frank ** :

Dimmers need to be able to operate the electronics when the light
is off. If the light is off, there's no current in the bulbs. Where
would the power come from then?

Instead, they leak a bit of current through the load and scavenge
what they need off that. If the bulbs are too small, there might
not be enough current flow to energize the electronics.

How di we get into talking about dimmers? This is about sensor lights
or security lights as some call them.....

Getting back ot the topic, I used to live with a relative who had a
light that seemed to do whatever it wanted. Sometimes it would stay
on forever, other times not work at all, etc......
I hated that thing. But it was not my house, so I could not change
it. Now, I have my own place and bought this fixture (another brand),
and find mine is pretty much the same useless P.O.S. I have tried all
kinds of adjustments and the light comes on everytime my cat gets
nearby, but sometimes will not come on until I am as close as 8 feet
away (and have tripped on the steps that are 12 feet away). I hate
these sensor lights. I dont think there are any that work as they
should, at least not in the lower priced ones.

I want to look into these remote switches that work on sending a
signal thru the power lines. This light is on a building that is
behind another building. The front bldg is visible from the house,
but the rear one is not, and has steps. If I could put a switch on
the front bldg it would solve all the problems. However, the wiring
would require digging trenches and be too costly and too much work.
Where can I get one of these remote switches that are wireless? That
would solve everything. I just found that stupid sensor ON and it's
noon and sunny. The stupid thing is costing a fortune in wasted
energy, and getting on my nerves real quickly.

Whoops. Got postings confused, and said "dimmer" when I should have
said "sensor". Sensor light electronics need power when the bulb is
off. Electronic timers do to.

Dimmers don't.

It's been my experience that the cheapies are erratic. Sometimes
they work as advertised, but most of the time the controls aren't
very consistent, and we find that they get worse as they get older,
and eventually die, either fully on or fully off.

[I assume Canadian winters and power spikes may be the cause of
most of that.]

X-10 technology stuff. The transmitter and receiver are connected
to power, and communicate via the power wires, but they're not
necessarily even on the same circuit.

The other option is to use a solar switch, which simply means that
the light will be on all the time it's dark.

Note, however, that X-10 in complex systems with multiple panels (especially
multiple buildings with their own main feeds), or with very long
circuits may not work well or at all, because the transmitter might
not be strong enough to transmit that far, or through that much
intervening equipment (especially pole transformers). Otherwise,
there'd be madness in a society where everybody's X-10 transmitters
controlled everybody else's receivers.

When the power is off there is no power to either to lamp or control
circuit. After all you want the lamp off.

After you turn on the switch there is power across the sensor control
circuit and a relay (depending on motion and/or night or day) would allow
full voltage across the lamp via the respective relay contact. This is one
way of doing it and is independent of the lamp wattage. Having the control
circuit dependent on lamp wattage is a poor design.

All sensor lights I've seen (not that I've seen that many... ;-)
have separate individual leads to each socket and the control
electronics.

Eg: in a two bulb fixture, each bulb has its own wire pair,
and the control circuit usually has three leads. Plus ground
screw or lead. Total of 7 or 8.

Which means that you could simply run the appropriate cable
(eg: 12/3) to the fixture. The red and black would go to two
switches. At the other end, you connect one hot (black say)
to the control circuit and one of the sockets, and the other hot
direct to the other socket. Connect neutrals to both.

If the were prohibited by code, I'd expect at least _some_ of the
devices I've seen have cable harnesses that prevent you from doing
that except by cutting cable. In other words, the fixture would
simply have one set of hot/neutral/ground leads (total of 2 or 3),
and no way (except by surgery) to connect to the bulbs independently.

While the installation instructions for sensor lights doesn't
explicitly allow/disallow that kind of connection, and hence
_might_ be considered violating the manufacturer's usage instructions,
I highly doubt that you'd ever get dinged for it. After all,
dual flood fixtures without sensor can be wired up this way,
and if it's a more-or-less standard pattern (metal plate, screws
to a J box, etc), they'd be hard pressed to justify it not
being code compliant.

Very good point. I know nothing about the code or its enforcement, but
each individual piece would still be wired according to code. They
would be assembled the same and there would be almost no difference
in the wiring.

Right. The hazard is more in the area of how the wires going
into the box are "derived". Eg, for some reason the hots being
on a different circuit and sharing neutrals in cases where they
shouldn't be.

If the OP had his existing light set up with the power feed
going to the switch and not the fixture, then switching
the box over to a dual switch and replacing the cable going from
the switch to the fixture to be /3 with ground, and not screw
up things like color codes, the likelyhood of him being called
on it by a particularly grumpy and overly-anal inspector is
extremely low.

Dunno.

I have two light sensor lights. The one with floods has two floods in
it. The door light has a 60 watt bulb.

To get them to go on automatic, each gives problems. IIU them C, I
have to do one of them at night and the other in the day to get them
on auto, or maybe both during the day, even though I usually want to
reset them when it's dark.

And if there is a power failure, they go on and stay on forever. I
gather the new ones only stay on until the next sunrise.

Try the two bulbs. It may work or may not. Othewise I think your idea
is a good one.

Thanks
