They are extremely efficient in their use of energy for producing light. Better even than compact fluorescents, and they do not liberate Mercury into the einvironment over their lifetime as CFs do. There are some adverse effects in their manufacture, and eventual disposal... as with any "product".
What else can I help you with?
Can a 3 volt battery light 5 leds?
It depend on what the rating voltage of the LEDs are.
Does LEDs comes in color light also?
The available color of LEDs are infrared, red, yellow, green, white, orange, blue, violet, ultraviolet and purple.
How many volt do you need if you have 12 led 3w and 700mA?
To find the total voltage needed for the LEDs, first calculate the total power by multiplying the number of LEDs by their power consumption: 12 LEDs * 3W = 36W. Then, divide the total power by the total current to find the voltage: 36W / 0.7A = 51.43V. Therefore, you would need approximately 51.43 volts for the 12 LEDs.
Why did it take so long to figure out how to make white LEDs?
There is no such thing as a white LED. You produce white light from LEDs by combining red, green and blue LEDs. Red LEDs were produced first because red is a low frequency of light. It was the easiest to make. Green LEDs were produced next because green is a higher frequency of light. It was harder to make. By combining red and green LEDs, you can produce yellow light. Blue is a very high frequency of light and is very hard to produce. Blue LEDs and blue lasers (as in BluRay) took a great deal of effort to create. LED technology and some kinds of laser technology are very closely related.
What are the two environmental factors that effect the function of enzymes?
tempeture,ph, solute concentration and salt content
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Are LEDs dimmable?
Yes, LEDs are dimmable.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
Does 5050 rgb leds shine through sheet of acrylic?
Yes, 5050 RGB LEDs can shine through a sheet of acrylic, as acrylic is a translucent material that allows light to pass through. The brightness and color visibility will depend on the thickness and quality of the acrylic, as well as the intensity of the LEDs. For optimal light diffusion and effect, a frosted or textured acrylic sheet can enhance the illumination.
What is environmental resistance and what effect does it have on population?
Penis
Are colored Christmas tree leds the same as the leds used in grow lights?
No.
How many colors do LEDs come in?
red, green, yellow, blue leds
How many resistors are needed 2 light up 5 leds?
Resistors don't light up LEDs. They're required in a circuit along with LEDs in order to prevent excessive current through the LEDs when the LEDs are forward biased. The correct resistance value depends on the supply voltage and the desired (rated) current through the LEDs, and there's typically one resistor in series with each LED.
What has LEDs in it?
Most modern torches have LEDs in them, several newer models of Audis do too.
Can a 3 volt battery light 5 leds?
It depend on what the rating voltage of the LEDs are.
In what year did SemiLEDS Corporation - LEDS - have its IPO?
SemiLEDS Corporation (LEDS) had its IPO in 2010.
What are the environmental factors that effect construction projects?
weather
