Homemade mood light with LEDs

    Hi. I want to make my own mood light.

    Let's say that the mood light is 300mm square and 30mm deep and I want the
    light to display just one colour.

    The front part of the light will be a clear translucent panel, in any event
    a panel to diffuse the light from the LEDs that are backlighting the panel.

    It seems to me that my cheapest LED option is to simply buy some LEDs
    and some VEROBOARD, and place the LEDs in a matrix, an array of LEDs.

    Now the thing is, I've no idea what type of LEDs to get, or how many.

    If I put LEDS 30mm apart in colums and rows in an array, I'd need 81 LEDs
    (No LEDs on the panel border).

    Can anyone please just put forward an educated guess on what I'm likely to
    be needing. Would I really need 81 LEDs do you think?

    Any idea of a suitable front panel material?

    Thanks a lot. Rich.

    I said:
    Well I just found now this; 600L spec.pdf

    Uses 6 LEDs! And it's 600mm square. 81 LEDs looks like overkill to me. :c)

    Isn't it just 6 x 17 = 102?

    Just a bit underkill.

    What this tells me is to go for a few bright LEDs. That looks like the way
    in the case I described.

    Wait a minute that's for 600mm x 600mm mood light.

    So, does this make the number of regular LEDs needed 102/4 = 25.5
