I've got 2 of the 288.2 w/heatsinks and a Meanwell HLG-240H-54A coming soon through Atreum.
They must be swamped as they keep moving delivery dates out a bit.
Didn't really do any research for pricing ahead of time..$225 to the door.
Wanna try these out as a replacement for my 4 bulb T5 for seedlings and veg.
Does anyone here know how they would perform against the T5s aside from running a lot cooler?
Also thinking of picking up 4 more for a 4x4 tent soon to come, looks like I should go thru Ebay for a better price.

You can look at HLG QB’s for reference as to how they grow. They use the same diods on their boards so you will see near identical results.
HLG and Atreum use different bins but they are negligible differences. Same diods just slightly different bin.
On Atreums 144.2 they use a bin with higher luminous flux and uMol/j than the similar sized HLG boards.

Can't decide on a driver for these 2 boards guys.

hlg-240h-54a
hlg-240h-c2100a

One of the LED guys please let me know. Atreum recommends the 54A while HLG recommends the 2100A. Does it really make a difference? Does one max out higher or have better efficiency? Thanks for the help guys.

How do you want to wire them. series or parrallel?

Series is safer for the boards, parallel is safer for you (or anyone else who may comment in contact with the fixtures.

I thought HLG already gets Samsung highest bin.

Agreed. I’d rather a damaged board than a damaged me.

That's fine with me also. How often do you hear of damage running parallel? For me i've usually heard of it with more boards. Should be fine parallel with only 2.

I have personally never heard of a case of thermal runaway.
LEDG stress tested boards and couldn’t even force damage on them.
Where have you heard of damage running parallel?

I’ve never heard of problems either way. It’s more a case of if something goes wroung what’s worth more, some leds or someone’s life.

those boards are 54v at 2200ma
if you wire in series and use the constant current driver (hlg-240h-c2100a) your two boards will be using ~108v (~54v * 2 in series) of the 119v at which the driver is capable of pushing 2.1a. this means that your boards will run at 113w each, despite the driver being capable of pushing 240w, you'll be using 230w
if you wire in parallel and use the constant voltage driver (hlg-240h-54a) your two boards will split the full current of the driver (4.45A/2= 2200mA each)
this means your boards will run at 120w each maxing out the driver.

in this case i'd say its really personal preference

Bang on answer I was looking for. I get really confused with numbers and it's always hard for me to compare 2 things. Sucks because I like DIY stuff and build stuff often but have to take my time or I over complicate things.

Well use the constant current driver than. Make sure you earth the fixture and be careful touching it. 1 short makes it a very zappy time. Personally I’d wire them in parrallel with the constant voltage driver so the voltage 100% stays under 200v

Zappy time eh ? That's why I steer clear of any DIY stuff !!
