A: Photocell and LED cannot work directly because these are different devices. But yes each independently can work as a unit all you need is some buffering.

When light strikes a photocell does the resistance increase or decrease?
When light strikes a photocell, the resistance decreases, allowing current to flow more freely.
Why does a photocell switch have a neutral wire?
The neutral is needed for the internal sensing electronics inside of the photo cell switch.
Different types of led lights?
There are several different types of LED lights available, each designed for specific purposes. Here are some common types: Standard LED Bulbs: These are the most common type of LED lights used for general lighting purposes in homes, offices, and commercial spaces. They come in various shapes and sizes to fit standard light fixtures. LED Tubes: LED tube lights are designed to replace traditional fluorescent tube lights. They offer energy savings and longer lifespans compared to fluorescent tubes. LED Strips: Also known as LED tape lights or ribbon lights, LED strips consist of small LED chips mounted on a flexible circuit board. They are versatile and commonly used for accent lighting, under-cabinet lighting, and decorative purposes. LED Spotlights and Floodlights: LED spotlights and floodlights provide focused illumination and are commonly used for outdoor lighting, security lighting, and highlighting architectural features. LED Panel Lights: LED panel lights are thin, flat lighting fixtures that provide uniform illumination. They are often used in offices, schools, hospitals, and commercial buildings as a replacement for traditional fluorescent troffer lights. LED Downlights: LED downlights, also known as recessed lights or can lights, are installed into the ceiling to provide directional lighting. They are popular for both residential and commercial applications. LED High Bays and Low Bays: These are powerful LED fixtures designed for high-ceiling environments such as warehouses, factories, gymnasiums, and retail spaces. LED Street Lights: LED street lights offer energy efficiency and long lifespans for outdoor lighting applications, including street lighting, parking lots, and pathways. LED Grow Lights: LED grow lights are specifically designed to support plant growth indoors. They provide the necessary spectrum of light for photosynthesis and are commonly used in indoor gardening, hydroponics, and commercial greenhouse operations. Smart LED Lights: These are LED lights that can be controlled remotely via smartphones, tablets, or smart home systems. They often come with features such as dimming, color-changing capabilities, and scheduling options for customizable lighting experiences. this information is provided by: world smart led
Where can you get a 12 volt photocell dusk to dawn switch to control a series of low volt lights hooked up to a 12v battery and solar panel?
Home Depot
How do you make a led simple circut?
It is simple LEDS do need a definite voltage drop to work must have a minimum current to operate. for a 9v battery source and a LED of 3.2v operating at 20ma the solution will be 9v-3.2=5.8v therefore to limit the current to 20ma a resistor of 5.8v/0.02=290 ohms not such an animal so a 270-300 ohms will work. Final note make sure that the LED power is not exceeded 3.2v x0.02ma=63 mw
How do you use LED floodlights?
LED floodlights are simply LEDs with a de-focusing lens, allowing the light to be spread out, although dimmer than if it had a focusing lens to concentrate the light into a tighter beam. Most of the time, LED floodlights are used to light up the side of a building, or a somewhat large area of land (7x7' perhaps), although keep in mind they can only shine so far before you probably are going to spend more money than you should on LED lighting, and should go for an Arc lamp.
Will a photocell work using dc voltage?
it creates a dc current
How would you make a simple led light emit a high decibal noise when the light is crossed?
You need two devices, a light source, such as an LED, and a photocell such as a selenium cell or cadmium sulfide cell. The output of the photocell can be amplified and connected to a switch which controls an audio oscillator to sound when the light of the LED, received by the photo cell is broken.
How can a faulty photocell be detected?
By covering the photo cell and if the relay coil doesnt work.
Can you wire a photocell to work at night instead of during the day?
Photocells are designed to work at night when it gets dark and turn off in the morning when it gets lighter. If the photocell is on during the day then it is not working the way it was designed to. Time to get a new one.
Where can you buy led light to illuminate your exterior of house?
I understand your trouble, we really need the inexpensive consumer product, but we often get what we pay, those cost-effective are relatively expensive. I am an environmental enthusiast and accustomed to using LED tubes in bedroom and the garage，as well as LED downlight in hall and outdoor LED flood lighting in courtyard, LED lighting can really save significantly large amount of electricity and maintenance costs, and more importantly bright and soft, With the help of my friend engaged in lighting design, I chosen a medium-sized manufacturer specializing in high power LED floodlights and other outdoor and indoor LED lighting , which with reasonable prices and various styles and excellent characteristics of waterproof and dustproof and heat dissipation have been praised by lighting designers and dealers and users， you can visit their PIR LED floodlights of their web named Lisida lighting to learn more features about PIR LED floodlights.
How would a faulty photocell be detected?
By covering the photo cell and if the relay coil doesn't work.
What does a led floodlight do?
Led floodlights which stands for light emitting diode are energy alternative lights to the regular incandescent light bulbs. They release less energy and much more efficient in lighting as well as time.
How photo cell function or work?
There is a lot of things when you talked about photocell... well in electronics world of terms the main functions of photocell are for sensing which provides limits or safety.Read more: http://wiki.answers.com/What_is_the_function_of_a_photocell#ixzz1lZGBI2wU
Where can you find the best led floodlights to replace your existing lights?
Check your local hardware, home improvement store, or garden center. There are many on-line retailers, like Amazon, who also sell LED floodlights. Your best bet is to shop locally and discuss your exact needs with a knowledgeable associate. There is no best, only relatively good,the most important features of LED floodlights are waterproof and dustproof capabilities and cooling capacity, as a designer engaged in the design and development of LED lighting for five years, I am willing to recommend a medium-sized LED lighting supplier specializing in offering outdoor and household LED lighting with absolutely reliable quality and excellent heat dissipation and capability of waterproof and dustproofs, from which there are twenty percent of the lighting retrofited and procured such as LED street lights and outdoor landscape lighting including RGB LED floodlights and pir LED floodlight in our city , you can visit their website lisida lighting for more detailed description of product features of LED floodlights
Am using a photocell in a 9volts dc circuit will this be enough to produce an output?
A: A photocell is like a variable resistor it will change resistance with light the ratio of dark:light resistance decides the output. So yes it should work with 9volts
Which kind of lamp have longer lifetime LED lamps or incandescent bulb?
Of course，LED light has longer life compare to incandescent light，because its lighting principal is semiconductor Lighting，which can turn the most electricity into lighting，the average life is 50000 hours，such as LED tube light and LED floodlights.
