The panel i made is with 4000K of 15 meters LED Strips.
Chose the 4000K "neutral white" because is not the very warm white but not either very cold white like the 6000K are.
Led Strip is rated 430 Lums/m so 15 X 430= 6450 Lums
For The power supply i used a simple 12V DC 6A (72 Watt)
Plexiglass used 500mm X 500mm 3mm white color
Power cable used for soldering the strips 3x1.5mm²
