Which RGB LED Matrix has the highest cd/m^2?

Post by wiliamho »

I need a very bright RGB LED matrix. Which RGB LED Matrix has the highest cd/m^2 ?

Is the 32x32 4mm pitch the brightest?

Or 64x64 2.4mm pitch

The datasheets don't specify cd/m^2 for all of them

Do you know much power 64x64 3 mm needs?

Do I need to buy the 5V 10A power supply or 5V 4A power supply?

8A would be recommended for this 64x64.
Next, you'll need to power all your panels. Each panel has a 4-pin power connector, and most of Adafruit's panels include a Y-splitter power cable which can be connected to 2 panels. The power supply current requirement increases according to the number of panels, but the voltage requirement is always 5V. Remember that we recommend a 5V 4A supply for a single 64x32 pixel panel, so our recommendation becomes 4×2=8A for 2 panels and 4×4=16A for 4 panels. By using dimmer colors and avoiding big solid areas on the display, you may be able to get by with a smaller power supply.
