    Here's a led with a Continuous Spectrum from 400 nm to 750 nm

    Combined, the four chips that have been joined together on one compact LED deliver very homogenous white light. Depending on the application, the light can be individually adjusted because the chips can be controlled independently from one another. For example it is possible to generate “Cool...

    $500 laser pointer at beach

    Green lasers are necessarily more complicated in their construction than flashlights and it's reasonable that this particular laser does retail for that much. Just look at lasers sold here Laser Glow or Optotronics.

    QD-LEDs emit over whole visible spectrum

    Researchers in the US have shown that a universal structure can be used to make hybrid organic-quantum-dot light-emitting devices that emit over the entire visible spectrum. These QD-LEDs might find use in RGB flat-panel displays in which red, green and blue QD pixels are deposited in one...
