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".

Can a 3 volt battery light 5 leds?
It depend on what the rating voltage of the LEDs are.
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
What are polarized LEDs?
direction of oscillation of electric field relative to direction of motion:verticalhorizontalcircular clockwisecircular counterclockwiseany combination of above
Does LEDs comes in color light also?
The available color of LEDs are infrared, red, yellow, green, white, orange, blue, violet, ultraviolet and purple.
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.
What is environmental resistance and what effect does it have on population?
Penis
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.
What is the effect of environmental protection?
higher prices for consumers
What are the environmental factors that effect construction projects?
weather
How the environmental affect the community?
Yes, environmental conditons can effect a community in a way that if a frog which have a moist skin if live in desert its moist skin would dry out to quickly in this way environmental condition do effect the way a community work
What was one negative environmental effect on the agricultural revolution?
One negative environmental effect of the agricultural revolution was deforestation. As more land was cleared for farming, it led to the destruction of forests, resulting in loss of biodiversity, soil erosion, and disruption of ecosystems.
Where could LEDs is used to reach its greatest effect?
Decorative lighting. General lighting in homes, offices, street lighting, industrial lighting sine LEDs provide more light per Watt compared to conventional light fittings, thus saving energy.
What is the environmental effect of computers?
realese a great amount of Co2
Which change is an environmental effect of building dams?
flooding
How many colors do LEDs come in?
red, green, yellow, blue leds
Are colored Christmas tree leds the same as the leds used in grow lights?
No.
