RGB LED pixel ball rated in .06A, the combination of red, green and blue color, as well as other electronic components. While RGBW LED pixel ball rated in .08A, the combination of red, green and blue colors, including its electronic components.
Formula as below:
P = IE
Power (Watts) = Intensity (Amps) * Electromotive Force (Volts)
1. 20mm Pixel Ball (Diamond Crystal)
RGB: 12v*.06A = .72W
2. 35/50mm Pixel Ball (Stripped Pineapple)
RGB: 24v*.06A = 1.44W
3. 35/50mm Pixel Ball (Hollow Milky)
RGB: 24v*.06A = 1.44W
4. 50mm Pixel Ball (Solid Frosted Acrylic)
RGB: 15v*.06A = .9W
RGBW: 15v*.08A = 1.2W
Power supply examples:
LRS-350, available in 5V, 12V, 24V, 48V. 350W indoor use only, from brand Meanwell.
HLG-320H, available in 5V, 12V, 24V, 48V. 320W outdoor available, from brand Meanwell.
To protect the power supply’s lifespan, 80% loading will do good.
LRS-350, 350W*80% = 280W
HLG-320, 320W*80% = 256W
Here comes the quantity for the 360° pixel ball families.
1. 20mm diamond crystal
RGB pixel ball quantity
280W/0.72W = 388
256W/0.72W = 355
2. 35/50mm Pixel Ball (Hollow Stripped Plastic)
RGB pixel ball quantity
280W/1.44W = 194
256W/1.44W = 177
3. 35/50mm Pixel Ball (Hollow Milky Plastic)
RGB pixel ball quantity
280W/1.44W = 194
256W/1.44W = 177
4. 50mm Pixel Ball (Solid Frosted Acrylic)
RGB pixel ball quantity RGBW pixel ball quantity
280W/0.9W = 311 280W/1.2W = 233
256W/0.9W = 284 256W/1.2W = 213
In order to avoid the power drop, sufficient voltage will be in need of some inline power injections.
So how many pixel spheres will need a power injection? Let’s plug in some ampere calculations, the table below shows different data including both the resistance of the various wire gauges and the allowable current (ampacity) based on a copper conductor with plastic insulation.
