What is overlamping? Overlamping is installing a bulb with a higher wattage than the recommended wattage for the light fixture. We've all been here before. The light bulb goes out, so you go to the closet and grab the nearest available light bulb.

What happens if you reverse the polarity of an LED? LED lights are considered polarity sensitive. If the LED strip is connected in the wrong direction, you will immediately know there is a problem. Polarity issues can cause the LED strip to dim, blink, not light up at all, or appear a different color.
Outlets may be installed above suspended ceilings, but flexible cords are not permitted. If flexible cords are not allowed in this space, why install an outlet above the ceiling? Because the receptacle can be used for portable tools. Not for use with cord and plug equipment that is fixed in place.
How much does it cost to run an LED light bulb for 24 hours?Assuming the US electricity rate is 16 cents per kilowatt hour (kWh), an LED light bulb that runs for 24 hours typically costs about $0.027.
Replacing a 100-watt incandescent light bulb with an LED will require a bulb that produces approximately 1,600 lumens. For a 75-watt bulb, the equivalent output is 1,100 lumens, followed by about 800 lumens for a 60-watt bulb and 450 lumens for a 40-watt bulb.
Generally, LED lights operate on very low voltages and therefore do not need to be grounded, so they may not have a ground wire.
Like all electrical equipment, LED lights can pose a fire hazard if they malfunction or overheat. However, the risks are relatively low compared to older lighting technologies.2x4 drop ceiling led light fixtures
Potential Risk: Without a ground wire, there is a slightly increased risk of electric shock in the event of a failure of the appliance. However, users are generally less likely to touch live metal components on a fixture, especially if the fixture is out of reach or has a non-metallic pull chain (2). that's right.
A final complication is that the National Electrical Code currently requires ceiling boxes to have a weight capacity of 50 pounds (2008 NEC 314.27[A]). I doubt whether screwing the box to the lathe would meet that requirement. The electrician was right in asking for an extra block, so it would be better to use a larger box.led drop ceiling lights 2x4
