LED world domination!
From the 350w SE you can run ~300 watts of LEDs on any number of LDD of any amperage so long as you do not exceed the voltage output of the LDD and also the wattage of the power supply.
Jedi is correct. When using the LDD drivers the PSU must only be sized to provide enough voltage for the longest led string attached to one of the LDD drivers powered by the supply. Using the LDD though the voltage can be much higher than the longest LED string if you want with minimal loss in efficiency.
How many LDDs and strings of LEDs that can be run is then calculated using watts from there on the output side. With the HLG you can pull up to it's rated watts and not need to worry about over head since it is designed to supply its rated maximum watts AND its rated maximum volts.
HLG is a much more versitile and durable power supply for DIY LED builds IMHO. If for no other reason than splashing water on it won't fry the thing since it is sealed to at least IP65 unlike the SE seriese which will deteriorate just in the presence of salty air in a cabinet.

While I don't fully understand this, but ibe gottta to agree with Jedi....
This supply says it will run 5 1000 ldd drivers at full power and each of the drivers can run 16 leds each...so that means it can run 80 leds.

Their numbers are wrong, though, and are based off of amperage on the power supply, as well, despite me asking them several times to change the site description lol
It would be pushing things really close to too much if you actually had 5 LDD 1000s running 16 xte LEDs though. Wouldn't leave enough head room for my liking and you'd likely need to turn the voltage up well past 48v........
They tend to oversimplify things on all their products and would be better just listing the parts specs and leaving the rest to the end user........
So this is the one correct? http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2148228_-1
I dont suppose you guys know of someone who puts yellow on stars...I have a couple, but the stars are tiny. Seeing if someone carries them on "normal" sized stars.
I got the limes all ordered up.

Well - it seems that it should be correct.
@ jedi and others.
So running LDDs from an HLG requires a different approach/calculation than running LEDs straight from an HLG?
I'm not trying to be the wise guy here, seriously, but I'm still not convinced - yet
it's just the penny has a hard time to drop 
So let me get this striaght; I could use an ELN 60-48 (1.3A) hook up 2 x 1amp LDDs,
and run a string of 10 XMLs at 1 amp from each LDD?

You'd be surprised how little that would get in the end. The number of people I have that PM/email me asking me to give them a list (preferably with links) of things that they'd need for their specific tank and instructions on how to put it together as dumbed down as possible is very high. There are surprisingly few people that are willing to do any research into putting things like this together, so I don't blame them for simplifying everything. There are some things on their site (and basically all the others, too) that are just not correct.
What do you mean yellow on stars? Do you mean yellow LEDs? I wouldn't bother with the Osram chips if you are using other amber LEDs, they are identical.
The ELN series does not have constant voltage capabilities, so they cannot be used as power supplies, only direct-drivers. If you were to use the HLG-60H-48, you could run up to ~60 watts of LEDs from them, which with the XM-L at 1A would be 20 of them, correct. For any 'normal' AC-DC power supplies that are not rated for use at maximum voltage and amperage, you will want to use no more than 80% of the total wattage that the power supply gives, so if using a 60w SE series supply, you'd be limited to running a total ofWell - it seems that it should be correct.

~48 watts of LEDs, which would be 16 XM-L. But who would buy the XM series to run at 1A anyways, that's about the worst buy at their price lol.
Yes Yellow led on stars. The amber is a bit more orange....I was really hoping for yellow.
Is that the power supply I need? I just want to confirm it is, so I dont waste more money.

Look at the spectral peaks and coverage of the Osram 'yellow' and Rebel amber - they're both 590nm because they're both amber LEDs. It's just like the 'turquoise' and cyan LEDs you have, they're both the same, as are the 'exotic' cool blue and XP-E blue. Just different names/brands for the same color of LED. If they were specifically chosen for their bin by you, that would be one thing, but from the 'typical' reef LED sources they are all unbinned and virtually indistinguishable.
Yes, that is the power supply.
Awesome thanks!!!! You have been very helpful!

Steve's sells the PC amber, it is preferred to standard amber LEDs, as it is phosphor converted and wide spectrum. This would be used mostly in the case of cool white-based arrays that are lacking in the warmer colors. You already have warm white, so it is superfluous.
Normal amber (and the rest of the Rebel/ES color line)
PC amber (and lime)
3 years ago, yes, the XM-L certainly had value over the XP-E and XR-E - but now, even the XM-L2 versus the XT-E and XP-G2 is almost a wash at the lower currents, and being twice the price compounds itSomeone like me 3 years ago

Isn't it funny to think that today you could replace all 64x of those XR-E with 7x Luxeon M at 700mA, crazy how far LEDs have come in such a short time!
I dont know...plasma tech is seemingly going by the way side...the television market is leading that trend. Plasma is becoming harder and harder to find, in favor of led tv's
