I have a confusing issue going on at the new place. I have two front exterior lights, one on either side of the front door. The one on the right has always timed off an on. It's on for 27 seconds and then off for 20 seconds. The timing is very regular which always ruled out a short and I always assumed there was some kind of timer in the wiring somewhere. The rear flood lights never worked and I finally figured out why. There was a wire in that same switch box that wasn't connected and they were supposed to be wired to same front lights. Since I don't want the rear flood lights to come on when I turn on the front lights I just finished installing a three switch box and three switches so the floodlights would have their own switch. During this process I actually removed the wire going to the right front light that times off an on and ran new wire. There was no timer. The main power supply line coming into that switch box also powers the ceiling fan/light in the living room. There is no timed off/on there and there is no timed off/on on the flood lights. That same light, however is timing off an on. To make it even more confusing, the light on the left, which is powered by jumping off the light on the right doesn't time off/on. How in the world can one light out of four on the same power source time off and on with such regularity? Any ideas?
Could the timer/ sensor be built into that one light fixture ? Sent from my iPhone using Bowhunting.com Forums
Never mind everyone. I figured it out. Since I knew it wasn't a timer or a short there was only one other possibility. I switched the super bright LED bulbs and now the other light is doing it. It's just a defective $40 LED bulb.
My first question was gonna be if it was an LED. When they go bad, they'll start to cycle on and off like that.
I guess this one was bad from the start because it's done that since it was new. It's only 4 months old now.
LED lights are no good. One of the problems - they can't emit heat by radiation, only convection. Which means, they need a metall heatsink and a proper airstream. Incandescent bulbs emit heat as infrared light. LEDs turn off when overheating (like yours probably), or burn out. The emitted light is not really "white" like sun light (or incandescent bulbs), but contains just a few narrow spectral bands to appear white. This gives a bad color rendering index (CRI, many colors appear distorted/wrong in LED light). And even if not directly visible, this light is not good for your health in the long term. But it's good for business ...
You know they told us that the old bulbs were part of the global warming problem so they banned them, well since the ban the temperature has continued to rise evidently so the build experiment did not work. I want my damn 100 watt bulbs back damn it.
Incidentally, the (worldwide) lighting industry was the first one to get caught in illegal collusions. Just google for "Phoebus cartel". As I see, the section about the out-of-court settlement in the mid-1940's disappeared from Wackopedia (your Primary Propaganda Source). And a few years ago, they bought a few politicians in the US and EU parlament, and got the old, less profitable bulbs banned. You know, if you can't force the customer to by your expensive low-quality crap, grease a politician and outlaw competiting technologies.
