Photo Control Sensor For Lampost

I purchased a screw in dusk to dawn sensor and when it get dark the light comes on but continuously blinks. When I unscrew the sensor from the light and screw the light bulb directly into the liight socket the light stays on.
      

I have a dusk to dawn light that is not working. The bulb appeared to be blown. I installed a new bulb and it still does not come on.  What would you recomend to check? What is the best way to check the sensor?
      

In a previous thread (Wire suitable for underwater usage), I enquired about what cord types would be suitable for underwater usage because I was building a submersible fishing light to attract baitfish.  Well, the light is done, and the bulb "farthest away" from the battery is by far the brightest in the chain (I hesitate to say chain since they are wired in parallel). 



Attached image "photo 1" is a picture of the light I made.  Notice the bulb all the way to the left is far brighter than the rest.



All bulbs used are the same spec, and look like this:



To wire the bulbs, I cut the flange off with a Dremel tool so that they would fit in the tube.  Two pair of them have their terminals soldered together (neg to neg, pos to pos...that's the "gap" you see in the lighting), and the first bulb in line is upside down, with it's terminals facing the incoming wiring.  The first bulb receives the wiring from the main line, then hookup wire is used to jump from those terminals to the next set, etc. 



There IS one anomaly with the final/far left bulb.  When I was cutting off the flange, I accidentally cut too far on that piece, basically severing the terminals from the bulb.  So, when wiring it into the circuit, I had to improvise and soldered the hookup wire directly into the solder points located on the bulb itself (instead of the underside).  Hopefully you can see what I'm talking about in attached "photo 2."



I have no idea why this anomaly would make the bulb brighter though.  Can anyone think of any other reason the bulb would be brighter?  Unfortunately, I cannot do any readings on the individual bulbs because I did not notice this until everything was soldered into place and the lamp sealed/waterproofed).
      

Hi everyone,



I'm pretty new to the whole homeowning/do it yourself lifestyle, and have a question about the light fixture in my kitchen.  Recently 2 twisted cfl bulbs went out, probably within 1-2 days of each other, and I am having a hard time figuring out how to replace the bulb.  I believe the lights in my kitchen are considered recessed lighting.



So when the first light went out, I hastily grabbed my step ladder and tried to twist the bulb out.  I should have looked more closely at the fixture because when I started to twist, the bulb popped in my hand.  No big deal, just a bunch of debris all over the place.  I looked at the fixture and it said I should pull straight down to remove.  Doh!  The second light went out a day or two later and this time I pulled straight down on the bulb to remove.  To my surprise the bulb came out, but at the ends of the bulb were 2 bare wires.  I had never seen this bulb in stores before.



Anyways here are some pictures I took of my fixture.  Can anyone tell me how I am to replace my busted bulbs?  Thanks!












      

I bought a landscape light at a thrift store to play around with.  It is definitely a well light.  It has a black shell and a round, rather flat bulb.  The connections are exposed on the back of the bulb and the wires screw directly into the bulb.  Looks similar to this:







The only difference is the bulb frame has a little clip that hooks onto the black part to hold it in.  I am interested in what kind of light this is?  I'm assuming it's low voltage?  How can I tell?  Also, what are well lights good to light?  I believe the bulb may say GE.
      

I have a kind of strange question:  How many watts is a 2x40W incandescent bulb?  Is it 40W?  Why is there a '2x' before 40W?



One of the bulbs in my light fixture above the bathroom sink burned out.  The light fixture uses three bulbs (decorative globe type).  I uncrewed the bad bulb, and it says '2x40W' on the base of the bulb (the metal part).  I went to Home Depot and they have the bulb type in 40W and 60W but both say 1x (1x40W and 1x60W).  The electrician at Home Depot wasn't sure what 2x could refer to on my bulb and suggested it might be that my bad bulb was in a 2-pack package.  Is that it?
      

Hello. I'm a new home owner and DIY-er. I have 3 fluorescent lights  in my basement. I just replaced the fixtures' older ballasts with new  T8 ballasts in the first two lights and they work fine. I am having  trouble with the third light's wiring to the ceiling. I cut and removed  the old ballast without paying much attention because I was able to wire  the first two lights without any problem. I connected the new ballast  to the bulb sockets in the fixture, just like I did with the first two  lights. When I went to connect the ballast's black and white power lines  to the ceiling lines, I was thrown off by a red wire, which I guess is  connected to the light switch.  In addition, this light is connected to  the one of the other fluorescent lights and both are controlled by the  switch. I have attached  pictures of how I have it wired.



The way I have it wired now,  the other light turns on and works fine when the switch is flipped.  However, this light has the bulb flicker and then not turn on. If anyone  can tell what I'm doing wrong from looking at the pictures, I'd  appreciate any help! Thanks!
      

Looking for a way to automatically keep my two outdoor bulbs shut off during the day.  The timers seem to be on the expensive side and from what I read the screw-in sensors don't work very well.  Would appreciate some recommendations.

I have an outdoor light fixture that I am trying to replace.  The house was built ten years ago.



When I removed the original lamp, I noticed one of the two leads was wired to the ground, and one was wired to the black wire, which is hot per my current sensor.  There are three wires in the box - black, ground (bare copper), and white or neutral, all from a single romex cable.  Unfortunately, I do not recall where the white was when I removed the original. 



I wired the new lamp per the instructions, something I have done many times before - black to black, white to white, and bare copper ground to ground.  Nothing.  The lamp and bulbs are brand new, and I have tried four separate bulbs.  I checked the black and neutral with my current sensor and with the switch on and the lamp installed this way, both show as hot. With the lamp not installed, the switch on, and the wires disconnected only the black shows as hot.  The switch is single pole, and appears to be wired correctly with a black to each screw on one side and a copper ground on the other.



Assuming the new fixture was bad, I reinstalled the old fixture correctly -  black to black, white to white, and bare copper ground to ground.  Still nothing. No light, and I confirmed the bulb is good by putting it in another lamp.   The only way to get it to light is to connect the neutral in the lamp to the bare copper ground.



I capped the wires, turned the circuit back on, and identified all the outlets, switches and fixtures on the same circuit.  I opened every one of them up (four lights and eight outlets) and found three (one switch and two fixtures in another room) where multiple commons connect.  All were properly connected.  My outlet tester shows all outlets as "correct".  I found no instances of grounds connected to commons or vice-versa.



Any ideas?  Is it proper to wire this thing the way I found it?



Thanks for any and all advice!
      

I'm installing a new outdoor light on the house (replacing a single flood with a motion sensor security light). I didn't realize until I took the old one off the house today that it's got a small rectangular junction box. The brackets that came with the new (round-based) light won't even fit in there. Is there any kind of adapter you can get, or is it a DIY kind of thing?



My biggest concern is keeping insects and water out of there. It's under the overhang, but I'd rather keep it sealed well if I can.
