Power Supply Needed for LED Project.

It's been over a year since i researched what i'd need and one bit of information i was not good at then, and completely forgotten since is this.

So, here's what i'm planning...
16 CW Cree XP-G2 (700MA)
16 XT-E Royal Blue (500MA)
16 XP-E Blue (1000MA)
8 XP-E Green (1000MA)
8 XP-E Photo Red (1000MA)
8 SemiLED Hyper Violet (700MA)
8 SemiLED True Violet (700MA)

Total Voltage 285.6V

Total Wattage 221.28W

Highest Amperage 1.0A

Total Amperage 5.6A

What spec of power supply to power LDD's on a breadboard (7 total) will i need? And where is the best / cheapest place to find this?
 
48 v 7 amps power supply or somthing over your amp draw ldd's will take up to 56 volts but 48 volt power supply is more practical and available

K, thought the Voltage had to equal the total voltage (so i'd need something with 250+), and amperage stayed the same and needed only 1A... know that's how it works for single Drivers, but never dealt with actual PSU's to supply a chain like this before.
 
Ok lets do it like this
Take each string of led's add the total volts for each string only keep it less than 48 v about 3 v
each string goes to an LDD supplied with 48 volts
 
The total amps comming from your power supply needs to handle your total load of 5 amps with a little extra say 7 amps
 
Got it, just always thought Amps were constant, but wouldn't it need to be able to handle the Voltage / Wattage as well? being able to supply enough to power each of the LDD's?
 
ouch, that one's pricey... really pricey.... i was expecting $150 or so, but that's more than double.... If i knew exact specs i was looking for... i'd see if i could find a cheap chinese knock of for that one part... only cause, thats the worse i've seen through all this.
 
Thats the one I use and I was trying to post it but screwed it up yea that will work do you need an ldd pcb I may have some extras
 
Voltage adds in series. Your 16 series blues ect are problematic.
Find the V(f ) for them and multiply by 16 (you need to do this for every string but NOT add them together for the ps needs, Take highest and add 3-4V for the LDD's , maybe another 10% for headroom..)
For the xp-g2 it is approx 3V x 16 +4 +5 =57 Volts ...
CREE Xp-e is even worse..at 1000mA V(f) is about 3.5 x 16 + 4 +5 = 65V
AND
Total Amperage 5.6A

plus 10% is close enough, rounded up to available power supplies..
As is , and all in series strings you would need a 65V PS w/ 6+ A output..
Not really practical..
and I'm not going to work out the other strings for you BUT
I'm pretty sure you need 1) 3 more LDD's to split the 16's to 8's
2)36V 6A 216W ps

Close enough cheap enough ps.. Good enough???

Better quality..

$18 vs $127................

NEW specs for amps needed w. 10 LDD's is now 7.8A plus 10% 8.58A

Could go with 12 of those blues on a 48

cost differential between adding 3 more LDD ($18) or going to the next highest PS ( 36-48) is pretty close to the same, and he doesn't lose any output..
Going lower in "class" say 6A vs 8A would save a bit but at the cost of output.........

hrm, now i'm confused about the 5up and 10 up boards ect... here's my product list so far and what i have planned out... Planned on all through RapidLED (plug and play, price ect all pretty reasonable).

16 XP-G2 CW $68 (Connect to a 700H Driver) 2.9V
16 XT-E Royal Blue $52 (Connect to the 500H Driver) 3.9V
16 XP-E Blue $56 (Connect to a 1000H Driver) 3.9V
8 XP-E Green $30 (Connect to a 1000H Driver) 3.8V
8 Cree XP-E Photo Red $26 (Connect to a 1000H Driver) 2.5V
4 Osram Oslon Yellow (not really needed, only used to "brighten" the lights. If you just REALLY want to, substitute XP-G2 "Warm White")
8 SemiLED Hyper Violet $36 (Connect to a 700H Driver) 4.0V
8 SemiLED True Violet $36 (Connect to a 700H Driver) 4.0v

56 Cree XP-E/XP-G 80 Degree Lens $70
16 SmiLEDs Violet UV Lens $20

7 Solderless LED Plug $5.25

2 Arctic Alumina Thermal Adhesive $14

2 LDD-H-4 Driver Board $30
3 LDD-700H Driver - $21.75
1 LDD-500H Driver - $7.25
3 LDD-1000H Driver - $21.75

Storm X Pro Controller $95
3D Printed Case for Coralux Storm X Controler $10

So, to be clear, for this to stay practical, i would need to get
3 LDD-H-4 Driver Board $45
4 LDD-700H Driver - $29
2 LDD-500H Driver - $14.5
4 LDD-1000H Driver - $29

With new prices updated there. With this setup, and the Storm X Pro being able to have 10 jumpers. This should be able to power all of it correctly? Now if i could just find a good tutorial on how to add a Arduino to it and get a Temp and Ph Sensor, ATO Control and make it bluetooth / wireless. That would be freaking perfect and everything i could ask for... I've been looking all week, but can't find a good tutorial on that for beginners... So, thought this would be the easiest / cheapest route to go for what's effectively 2 XR30w EchoTech Lights over my 6 ft 150G
