  • Why Does Brightness Matter?

    There are two important things to consider related to the brightness of your sign: how well and how long it will compete with the Sun.

    How well a sign competes with the Sun
    Ensuring that your sign is readable during the day is vital to the success of having passers by read your sign. The brighter the display, the better able it is to compete with the Sun.

    How long a sign competes with the Sun
    LEDs do not burn out, however they do grow dimmer with use. The closer an LED gets to 1500MCD, the less effective it is at competing with the Sun. Starting with a brighter display ensures that your investment will be readable for many years into the future.

    Stewart LEDs are among the brightest available to provide you with a sign that will be visible 24 hours a day, and for years into the future.

  • LED Definitions


    A light-emitting diode (LED) is a semiconductor device that illuminates when electricity passes through it. LEDs do not contain filaments like regular light bulbs, and they do not have delicate parts that break or burn out over time. Industry standard LEDs are rated at 100,000 (11+ years) of constant use.

    Pixels Pixel

    A pixel is a point of light. An LED display is made up of an array of pixels, multiple points of light appearing as dots. A pixel can be as small as one LED or it may contain a cluster of LEDs that act as a unit.

    Pixel Pitch Pixel Pitch (Center-to-Center)

    The pixel pitch or center-to-center measurement is the distance from the center of one pixel to the center of the adjacent pixel. Pixel pitch can be measured in inches or millimeters.

    Matrix Matrix

    The matrix of a sign is the number of pixels vertically by the number of pixels horizontally. For example, if a sign has a matrix of 32x96, this means it has 32 pixels from top to bottom and 96 pixels from left to right. A larger matrix allows more text and more of a graphic to appear on the display at the same time.

    Millicandela Millicandela (MCD)

    A millicandela is a unit of measurement for the brightness of a single LED. A millicandela is equal to 1/1000 of a candela, which is comparable to a single candle's brightness.

    Nit Nit

    A nit is a unit of measurement for the brightness over one square meter of a display. This value takes into account the number of LEDs per pixel, pixel pitch and millicandelas. Your sign's nit rating can help you determine which sign is a better value when comparing products and companies.

    Viewing Angle Viewing Angle & Viewing Cone

    The viewing angle is the maximum angle that text and images can be seen on a display. A narrow viewing angle causes the text or image to "disappear" from the display as a viewer moves away from a position directly in front of the sign. The viewing cone is simply double the amount of the viewing angle.



The quality of the sign is superb, and we have already had numerous comments on how the design and features match our church.
