these new higher powered leds have me a little confused and was hoping i could get a little direction from my friendly forum. i promise i did a search however there doesnt seem to be much info on the newer leds.
so lets start with, it seems the new leds are an Array of led emitters in a 3s3p config.
with specs:
Color: white
Luminous flux: 800~900LM
Forward voltage: 10-12V DC
Forward current: 1000mA
Power: 10W
Lighting angle: 100~120°
like so
**broken link removed**
now there are other 10W led arrays that have a bit different of a packages (kinda round), and kinda looks like a 4s4p (but i dont know)(cant find anything)
with specs
Forward Current: 1000mA
Forward Voltage: 11V
Power: 10W
View Angle: 140°
like so

So simple first question are these LEDs basically the same minus manufacturing packaging, and does any one know if one package is a better design that generates less heat than the other?
next is where i may be over thinking myself and a bit confused about constant current power. maybe its as simple as watt to watt(9X 10Watt = 90Watt or higher power is needed).
say we wanted to build a 9 led unit. i understand that a Driver is required. Similar to the resistor when using small leds it limits current to the forward current value. (i hope this is correct thinking).
so back to the design of the 9. am now having issues understanding how to select and wire the driver.
my thought is using a 100 watt driver with these specs
DC:28-33V
DC:3.0A±3%
100W Max
**broken link removed**
one would wire it in 3S and 3P... my thought is the 3S will get the forward voltage to 33V and then the 3P is to maximize the leds per driver
HOWEVER im completely lost.
it seems the driver is capable of 3 amps output with 9 leds im creating 9 amps of forward current.
am looking at it wrong and im supplying 1 amp to each series of leds totaling 3 amps for the 3S3P led array?
thanks in advance for the help.
