Cool!

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

I found this one on Craigslist a few years back, http://www.wickedlasers.com/ is the company that makes them. Seems like I read where you cannot order some models in the US anymore.

Nice! If you get a strong enough one, you can shut off street lights by tricking the photocells lol. I want to get one to try that lol. I've successfully shut the one in front of my house with a 100W halogen spot light and a long extension cord lol. My neighbors probably thought I was trying to pick up alien signals with my "contraption" (a medium base socket mounted to a PVC work box with an extension cord coming out of it).

I used a crap 5mw grew laser and it turns it off fine. The streetlight I've done this to is day burning, so I think I blinded it.

Lol! Wow, though if you blinded it wouldn't it think it us dark all the time and just stay on? . Now I need to try and turn off our security light.

No it would be a coincidence that you "blinded" it I think. @ mrboojay; Dayburning is when the light just stays on all the time.

Yeah I know what day burning is. I miss read it and I thought he said that it was dayburning and then after the laser it stopped dayburning...my bad.

The laser may have damaged the cell causing it to fail in the open position.

Oh lol. That would be one strong laser to open the circuit inside the photocell. (It would have to melt something inside that opened the circuit lol)

It doesn't have to physically damage it. Zapping the photosensitive part with a vey bright light could damage it and when these cells fail they are designed to be fail safe, in other words failing in the open or on position. Otherwise, whenever a cell went faulty an area would remain unlit after dark, which is especially disastrous in the case of group switching!

It thankfully is a single light, I think the photo cell just got damaged.

When the load is on it's in the closed position. An open circuit doesn't light. When the photocell "sees" light, it spreads the contacts apart and opens the circuit. Photocells are designed with "Contacts normally closed", but they do in fact make special "Fail Off" units, with contacts normally open, so when the PC fails, it does so in the open position with the load off. Even with standard photocells, I've seen a number of standard "Fail On" photocells that have in fact failed in the off position, leaving the lamp off.

For freeway lighting here, they use Fail Off photocells in the contactor relay cabinets so that they don't have around a hundred 250 and 400W lamps running 24/7 and sending the energy bill soaring through the roof. Makes sense to do that on freeways since freeway lighting is an amenity, not a necessity. In a suburb or downtown area, it's more of a necessity due to pedestrian traffic.

Almost all are. The Fail Off ones are special-order, typically.

I noticed some photocells i have will turn off the load instantly upon being exposed to light and the others will take up to a minute in light to shut off the lamp. Why?

I think my street has a mix of these also because during thunderstorms at night, bright lightning flashes cause some streetlights around here shut off and restrike, its always the same fixtures that get interupted

I have used laser pointers to turn off the light outside my house too. It even can shut off a NEMA in an alley pretty far back.

Any machine is a smoke machine if you operate it wrong enough.

I find it difficult to use a laser to shut off a street light fitted with a delayed photocell. I cannot hold the beam steadily long enough to trigger it. Instant response photocells are easier to trick like this.

Electronic PCs almost all have a 2-second delay. Mechanical ones are instant response. thermal ones you gotta wait up to two minutes. Those things are junk anyway.

Most newer LED-rated photocells are "blind" to LED light, meaning lasers will not shut them off if the laser is LED-based. The actual idea behind making the photocells blind to LED light is to eliminate false shut-offs from high ambient light (but it assumes all ambient light sources are LED)

Thanks @streetlight98

How do the LED ones know what is LED and what isn't? Unless it uses a wavelength the sun gives but LEDs dont?

It could have a filter that blocks blue light, since LED has a lot of it.

I'm not sure how it works but I have ine made by DTL and the silicon eye is tinted a blackish color. I think wattMaster is right; has something to do with filtering out a certain color/wavelength LEDs out out.

I think they work on infrared light from the sun, instead of using visible light.
Illuminated road bollards use them, as they have the PC with the lamps and gear in the base unit, so use infrared cells to avoid the lamps switching themselves off.

Makes sense, as other artificial light sources will activate the "LED blind" photocells. Only thing with using IR instead of visible light is inconsistent turn-on footcandles rating. When the first silicon eye photocontrols came out, they were too sensitive to IR light. So they came out with "IR filtered" silicon eyes that were blind to IR light, to give more accurate turn-on times.

Cadmium Sulfide sensors are the best for mimicking the human eye when it comes to light detection, but cadmium eyes "drift" over time. If you orient the control North, the "drifting" doesn't become much of an issue, but it's rare to find places that actually do that.
