[video=youtube;DXGxPgOGqj8]http://www.youtube.com/watch?v=DXGxPgOGqj8[/video]This new powersupply HLG-185H-C are new constant current high voltage power supplies that do away with the need for drivers and are 94% efficient. The HLG-185H-C700 is 700ma constant current and have variable voltage depending on the voltage drop and go up to 285v. That means I can hook up 7 2530's in series without any drivers at 94% efficiency and the power supply is only 75 bucks.

Got a link to a shop that sells it?

www.oemstrade.com has been useful to me, makes it a bit easier to shop around.

When I searched for HLG-185H-C1400 it didn't show up, only when I searched for HLG-185H-C. Thanks!Ggle says Mouser
Quite okay price for a driver with that high output.

I think:

plus these:

Likely the best solution I have found so far.

1000mA for the Meanwell LDD-Bucks, 1400mA for the HLG-185H-C1400
less power plus more money and wiring, not really a better solution!

You will only be able to run3-4 LEDs in series with the 1400mA HLG-185-C1400 at $100 a pop Plus shipping. If you think it is going to be less expensive then the parts I listed you are wrong.
$100 for a 600 watt power supply, and $5-8 per ldd-1000 running 10-12 leds would be about $250 for the power parts. Same price you would be looking at with the other power supply, but with much greater redundancy.

again, for the them Output you need 40% more leds & drivers.
the RCD-48-1.20/M is the highest Buck-CC-driver i know. 1200mA

but for twice the price!

It's not that simple. If you are wanting to set up a string of cxa3050 you could run 3 off the power supply you are referring too. Or you could run the cxa2530s with the 700mA version, run them below the 800mA rating and run 6-7 of them. But if you wanted to build something that had 10-12 cxa2530 runninn at 1000mA each it would make way more sense to do what I listed. There also happens to be a 93 CRI version of the cxa2530. Using the components I listed would give about 20k lums at nearly perfect grow spectrum light for $350-400.
Just look look how sexy that light purple 93cri spectral curve is!!!

I would conceded that if you wanted to do a light for a single plant as per this thread with 3 cxa3050 or 6 cxa2530 that the HLG-185 is the way to go. But if you want to go bigger then scaling up with the ldd-1000h bucks would be far more efficient using the cxa2530s and progressively larger initial 48vdc power supplies. You could run about 18 cxa 2530s off a 1000watt power supply and ldd bucks. They are also going to be coming out with and ldd-1500 buck I am not sure it will be higher enough voltage.

I value the importance of redundancy but to me efficiency is more important otherwise why not just use hps your 600 watt 48v powesupply is only 88% and with drivers drops it to 83.6% which 10% less then the 185-c . pushing the LEDs past their rated ma further reduces efficiency of the LEDs while me going below their rating actually increases it. Lastly it might not seem like a lot but it adds up and these lights could last 10 years and so it pays to make them as efficient as possible
Thanks, I'll give it a shot.
