Do LED light fixtures need to be grounded?
Not for the operation of LED’s.
If the fixture has a metal housing or some other conducting material, then yes, although the risk is quite small.
The housing would have to become energized (unlikely), you would have to touch it and provide a path to ground some how to get shocked.

What is the difference between LED and Edison light bulbs?
The main difference between LED and Edison light bulbs is the technology used to produce light. Edison light bulbs, also known as incandescent bulbs, use a filament that is heated by an electrical current to produce light. On the other hand, LED bulbs use light-emitting diodes (LEDs) to produce light.
There are several differences between these two types of bulbs in terms of their energy efficiency, lifespan, and light quality.

LED bulbs provide numerous environmental benefits compared to traditional incandescent bulbs:
1. Energy Efficiency: LED bulbs are highly energy-efficient, utilizing significantly less electricity to produce the same level of brightness.
2. Lower Carbon Footprint: LED bulbs contribute to a reduced carbon footprint due to their lower energy requirements.
3. Extended Lifespan: LED bulbs have a significantly longer lifespan compared to incandescent bulbs.
4. Non-Toxic Composition: Unlike incandescent bulbs, LED bulbs do not contain hazardous materials such as mercury.
Heat Reduction: LED bulbs emit considerably less heat than incandescent bulbs.
By embracing LED bulbs, individuals and communities can contribute to significant energy conservation, emission reduction, resource preservation, and a healthier environment for future generations.
What size of LED lamp will be equivalent to a 150-watt halogen lamp?
To find the equivalent size of an LED lamp to a 150-watt halogen lamp, you need to consider the lumen output. Halogen lamps typically produce around 15 lumens per watt, so a 150-watt halogen lamp would produce approximately 2250 lumens.
LED lamps are more energy-efficient and can produce the same amount of light with fewer watts. On average, LED lamps produce around 80–100 lumens per watt.
Using this conversion rate, you would need an LED lamp that produces between 22.5 and 28 watts to achieve the same brightness as a 150-watt halogen lamp.
It's important to note that this is just a rough estimation, as different manufacturers may have variations in their lumen outputs

Which is better, LED or incandescent lights?
It depends upon what you mean by better. What criteria would you use to decide which is better.
However, we can say that LED lights tend to be more efficient. Incandescent lights generate quite a lot of heat so not all of the energy is used to generate light.
You can get more light per unit energy with an LED light than with an incandescent light. If energy efficiency is your criterion for deciding which is better, then I think LED lights are better.

How do you account for glare when designing lighting for indoor spaces?
Chose lighting products that are glare free ie they limit light in the 50 to 90 degree zone to test it put on a baseball cap or shield your eyes if you feel some relief you are experiencing glare
Finding quality lighting products that shield fromhlate is getting more difficult particularly in the residential sector LED products tend to be available with limited glare control and optical cut off

What's the difference between an LED wall washer and an LED strip light?
a. The main difference is the light beam angle and waterproofness.
b. for led wall washers, it's a narrow beam angle light like 20 degrees or 30 degrees; in this way, the light can reach 1.5–2.5 meters on the wall to wash the wall. Also, LED wall washers are always used outdoors, so nearly all of them are waterproof.
c. For LED strip lights, the beam angle is 120 degrees. And there are both waterproof and non-waterproof versions on the market.
Why are LED lights so commonly a cool white?
LED White light’s actual LED is of InGaN type, emitting around 400 to 450nm (Violet to Blue light). This light is then used to pump phosphors that will re-emit light at the white visible wavelength.
Two issue occur
1) There’s still a bit violet-blue light present in the final spectrum, giving the bluish hue that is typical of the cool light
2) it is more efficient to pump phosphors that re-emits closer to the original pumping wavelength.
BTW, fluorescent tubes are also typically cool-white for the same reason.

What is a LED Solar Light?
"Light emitting diode" is the abbreviation for "light emitting diode." A diode is a two-terminal electrical component that only conducts electricity in one direction.
The diode emits a brilliant light around the miniature bulb when an electrical current is applied.

Why are LEDs more expensive than traditional light bulbs? Is the investment worth it in the long run?
LEDs are more expensive than traditional light bulbs because they contain special circuitry that converts alternating current to direct current.
The investment is well worth it in the long run because LEDs last much longer and use much less energy than traditional light bulbs.

Can LED strip lights be used outdoors?
Just as with any electrical device the Leds and surrounding circuitry can be made impervious to dust and moisture by sealing them.
They will then be graded according to the IP ( ingress protection) standard
For instance IP 65 means it is protected against airborne dust and water sprays, while IP 68 means it protected against airborne dust and submersion up to a 1.5 metres under water for up to 30 minutes.

Why do CFL and LED bulbs burn out?
LED’s do not burn out unless they have been overdriven to make them appear brighter than they should. It is usually the electronics that fail because the designers have not properly allowed for the way they work and cut costs.
12V LED bulbs should be the most reliable of all. But I found they were being overdriven, burning the LED, and many had bad soldering on one of the wires, also causing failure.

Why does an inverter inside an AC LED bulb have a short lifespan? Is it because it is made of small gadgets?
Generally what makes electronic components unreliable is them getting too hot.
Lightbulbs have limited space for the electronics, and cheap ones don’t devote enough effort and expense to getting rid of the heat - so they run hotter than is desirable and fail sooner.
Better-quality LED lamps have large finned metal heatsinks to help get rid of the heat, the components run cooler and last longer - unless the lamp is put in a fitting with inadequate ventilation.

Is it true that LED or artificial light can't be separated into a rainbow?
Any light can be separated into the same wavelengths that were produced by the LED or other lamp. Perhaps red, green, and blue Or maybe blue and yellow.
There are various combinations of discrete wavelengths that the eye can perceive as “white”.
You can find the spectra of various LEDs or other lamps.

Why do LEDs not glow as much as they used to in earlier times?
Modern LEDs are generally brighter and more efficient than earlier versions. Perception of brightness can vary due to factors like ambient light and personal preference.
LEDs consume less power compared to older bulbs, so they may appear less bright in comparison. Different LED types and designs serve specific purposes, and dimming capabilities can also affect perceived brightness.

Do cats like red LED lights?
No… The first reason is that LED lights tend to flicker and change a lot and that can peeve them. The second reason is that cats are red-green color blind, so they have a hard time telling the difference between red and a lot of other colors. It won’t stand out much to them.

How does the energy usage of an incandescent light bulb compare to that of an LED light with the same wattage?
Watts are watts, so 10 watt incandescent will use same amount of power as 10 watt LED bulb. However LED bulbs are much more efficient and will provide at least five to eight times more light output comparing to incandescent light bulb on average.

Why do some light-emitting diodes (LEDs) flicker but others don't even with the same power source and wiring?
Inside the light bulb structure, there is a circuit that transforms 120vAC (US) to about 15 vDC that actually powers the LED.
The sporadic flashing from an LED light is due to the circuit is dying. It is gasping it’s last breath - or so to speak. I guess it is letting you know it’s time to replace it.

Is it safe to leave an LED grow light on for 18 hours a day?
There are so many variables that come into play when it comes to leaving LED grow lights on for long periods of time. Some of the factors that would affect the safety of leaving a grow light on for extended periods of time include the type of LED light, how powerful it is, and the distance between the light and the plants.
If you are concerned about the potential health risks associated with leaving LED grow lights on for an extended period of time, you should consider using a COB light rather than an LED light.

If we replace an MV lamp into an equivalent LED lamp, which point should we need to consider?
Heat removal and the lumens output. MV lamps run very hot most fixtures do not dissipate heat well. High power led arrays do not like heat.
Also pay attention to the light distribution all the light should be directed downward and not in the sky.
Depending on the use of the area you may be able to use less light especially if the color rendition is considered.
