DIY LED HELP NEEDED

[vikizameriky]

Dear friends,

Could you please help me to better understand difference inbetween MW-HLG and MW/XLG?

I am building a setup
Luminus CXM32-HMs

I am thinking about mounting 2 or 3 of them on HLG-240-54B
at 2 / 2225mA
at 3 / 1484mA for each,

Now I run into a XLG driver and 240-M
2 lamps up to 2100mA
Seems leggit also, plus the drivers comes was cheaper
(I am not working on a single lamp,
It continues 3xDriver so I plan to reach 600-700w on 150x150

Appreciate any opition/help.

Cheers

From a very brief search, it seems the XLG might be a bad idea. You have to set them yourself, and it's quite easy to set them way above what they can actually achieve. They will get hot and cycle, but before them your LEDs might fail. It's more like a power supply that an LED driver in that way. There is the ELC if you want a cheaper HLG and they cost about the same as the XLG. Getting more user friendly control but loosing the waterproof specification. The ELC range covers 240w but much bigger and you have to buy the HLG. Leave the XLG for street pole installs. Where is narrow band of acceptable operation can bother someone else

Thanks for the hint,

I ve found an interesting option, please if you could let me know your opinion about it, and so it is:

connecting:

2x HLG-320H-48A
https://www.meanwell.com/Upload/PDF/HLG-320H/HLG-320H-SPEC.PDF
they do 6,7A each


option1: 2xHLG to CXMs (3x3)

to me(but I am laic to this) seems 13,4A /devided by 9COBs as a fair solution, that would drive them (at 1489mA) what is below their typical(that is 2200mA), also should not make them ultra hot

option2: building it separatelly: 2x (each 1xHLG-320H-48a to 5 cxms) in case it was somehow safer, but optionally I would prefer 1 dimmer as an option



Also I am mounting them to
DUALLED-19037

(maybe stronger fan if was necessary)

3x3 in a square tent offers too much light in the middle. It's actually better to take the middle one out. That space gets the over-spill from 8 lights, which adds up.

I'm honestly not sure if two drivers can go in parallel on the same set of lamps. Probably so but it's unconventional. However with 8 lights it's 4 each. Two separate systems, which is a better option as one day something will certain break.
