Hello! I want to wire some LEDs and I'm not sure how to do it.
I want to wire as many 12V 10W LED Pads I can from a Philips LED Power Driver 60W 24V 2.5A. What is the best way to do it?

The solution I found is 2 series of 3x parallel LED but I'm not sure is a good solution.

Full specifications of a LED:
Specification(10w)
Model Type: High Power Integrated Chip lamp Beads
Chip size: 24MIL*44MIL
Integrated approach:3 Series 3 Paralleling
Forward Voltage:9-12V(if use DC 12,Recommended Series a about 1.50 ohm resistor to use)
Forward current: 900mA
Luminous Flux: 90-110LM/W
Color-rendering index: 60-85
Beam Angle: 170 degrees
Working Temperature: -20 centigrade to 60 centigrade
Color Temperature: Warm White: 3000-3200K
White: 6000-6500K
Lamp Body Material : Pure Copper Bracket
Life Span: 120,000 Hours

2 x 3 with current limiting resistors as you already are considering.

Only issue will be how honestly rated the power supply is. If it's good running at the full 60 watt rated output should not be a problem but if its a cheaper unit you may have put a bit more resistance in series with each LED pair to bring its running wattage down to 8 - 9 watts each.

After the first hour or two of running at full output you will know if the power supply can handle that long term or not. If its hot but still touchable it's fine but if it's on the edge of skin burning hot you may have to reduce the load a bit.
