Which is a more powerful light - 95 leds or 128 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.

Why do green leds on modern stop lights fail before leds of other colors?
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 is a superflux led?
Superflux LEDs are the pinnacle of LED lighting. At a glance at the specifications it would appear that they are not as bright as the 3mm and 5mm LEDs, however with their 110 degree viewing angles they kick out an enormous amount of light. Making them perfect for vehicle stop lights, signs and many many more applications. Superflux LEDs are also known as Piranha LEDs. http://www.phenoptix.co.uk/Superflux_LEDs_s/35.htm
