Thread: IR pills

    Default IR pills

    Hello all,

    Just wondering if someone can expand on how i can differentiate between different IR flashlights regarding what actual output they give.
    I understand the wavelength characteristics but what discernible difference would there be between say a Dereelight IR pill that is rated up to 4.2 volts ( single cell) compared to a multi cell pill rated up to 12volts?

    Emitters outside of the visible spectrum are generally rated by radiant flux (W)
