No, you only need one of the HLG. They are made differently than most power supplies, they're made to run at 100% duty, and you won't even be hitting that.
Stellar...thank you very much!
Shoot, good catch Jedi, I didn't see the label on the PSU.....
Foo, if your longest string is still the 10 Royal Blue then you can perhaps use the CLG 150 36A meanwell driver as your PSU. they are slightly less efficient (only a few percent) but they have been selling on ebay for $12 shipped lately if there are any left they are a great deal. Work the same as the HLG. Just an older model.

True story, thought they sold out of those?
So to be clear...this is the one I want?

*not saying that is where im buying it, just did a quick google search and that came up*

.......is the seller that's had the CLGs in the past, they have re-listed a few times but they sell out FAST!
Otherwise Search on Octoparts.com for the model you are after to compare prices, generally powergate has the lowest price on meanwell but depending on where you live shipping can be steep sometimes.'

That is where I bought mine. Had it in 2 days, great seller for sure. Had 53 available when I snagged it.
I don't want to interfere,
but why an HLG instead of a SE-350-48 (unless of course, you have an HLG laying around)
With an HLG you're using an expensive dimmable CC LED driver, with much more capability's, just to run other CC drivers.
I have 4 HLG's running 144 XLM -LEDs.
You only need a power supply to power up the LDD drivers
Saves you an arm and a leg

I have no idea...I will look into that...unless im looking the wrong power supple...the hlg's aren't that expensive.

The HLG is a different class of power supply than the SE series. Not only are they rated for both constant current and constant voltage use, they are IP rated (IP65 for adjustable models, IP67 for sealed models), and they are designed to be fanless while keeping efficiency above 90% (95% typical). I can personally verify that while the Meanwell SE series is a step above the typical Chinese garbage typically used, the HLG is much superior.I don't want to interfere,

If they think the cost is very high, they're probably looking at the wrong place to buy it from - the HLG-240H-48A's typical retail price is ~$83, but there are some places like ReefLEDlights that are trying to sell them for $125.
HLG it is!!!!
I agree its the best of the best, but the HLG is not a power supply, it's a LED driver
An HLG 185 - 48 (3.9A) will cost you around $100,-
Besides that, you can only run 4x 1000mA LDDs from it - whereas the SE can run 7x 1000 mA LDDs or 10x 750 mA LDDs.
Not sure you need 48 V, maybe by adjusting the layout a 24 V will do (max 7 leds on a string or LDD)
An HLG 185 -24 (7.9A) will cost around $70,- and can also have 7x 1000mA or 10x 750mA LDDs.
The amps determines the amount of LDD drivers you can run from the power supply, and the voltage determines the number of LEDs in a string
Hope it helps a bit.

Im seeing that power supply for less than 65 shipped....
Jedi seems to believe I only need one power supply for my set up?

It doesn't. The voltage output of the power supply determines the voltage output of the LDD (which is input minus 3-4v) and the wattage determines how many LEDs you can power. The amperage of the power supply does not matter except to calculate the total wattage output.An HLG 185 - 48 (3.9A) will cost you around $100,-

An LDD driver that has 48v input and is only powering 2x 3v LEDs at 1A does NOT pull 1A from the power supply, or it would either be pushing 48 watts of power through those two LEDs (which would only need 6w total) or would be dissipating 42 watts of heat, which would absolutely destroy the LDD. The 1A LDD will only draw ~187mA from the power supply, which is exactly how much it needs to power the LEDs and for the 3-4v voltage drop at the LDD itself.
Im glad you understand that...because I sure don't, lol...im going with the hlg power supply you suggested and will call it a day

All you gotta remember is voltage tells how many you can run per LDD, and wattage tells how many total you can run.
nope, the voltage does.
of course it does.
No matter if it's 1 or 15 LEDs, it is always 1A what the LDD has to deliver to run 1 or 15 LEDs at 1000mA
jedimasterben

Voltage determines how many LEDs you can power in series from a single LDD, it does not determine how many LEDs in total you can power from all the attached LDD, that is determined by wattage.
You're confusing input and output amperage. In my scenario above, the input is 48v 187mA, the output is 6v 1A with 3v 'lost' in the LDD driver.
