Take it easy. Could you maybe give us what is the exact driver? Also comment on how you got the voltage readings, multimeter? if so you should have the current aswell which would be the end of this mystery. the wattage you quoted is 229w, is that on the ac or dc side?

if its a HLG240-48x, datasheet says 5 amps output, 45V x 5 amps is 225 W. if the 229w is on the dc side then there is absolutely no anomaly. if its on the ac side then it seems your driver might be a few % under spec or measurement error. Again, you should check how much current it gives.

it might well be that your driver is a bit under spec which wouldnt surprise me. Unless you wanna send it back to china and argue with the supplier you might be stuck with it.

Never buy a driver from china unless you see it as disposable and unwarrantied. theyre pretty much the same price from digikey anyways.

Edit: sorry, i realize you posted the driver, 48b version on last page. Is there a dimmer? If so you can probably squeeze out more power by disconnecting it for full power.
229w Ac: something up, either in measurements or driver not outputting all 5A or being magicly efficient (like 100%)
On DC side: its normal, see dimmer advice above.
Hope it helps.

Hi rocket soul I'm gonna get better readings that ain't exactly the volts with the dimmer unhooked it's like 45.7 volts I think I'm waiting for it to come on and I will get exact reading and the 45 volts is on the DC side I'm using a lcd display ammeter the board is ran 16 series and 18 parrallell so I'm pretty sure it should be 45 volt boards I really like this kit it's nice and clean the heatsink it's on barely gets hot I mean it just gets warm to the touch it's 3000k I put up some mono 3 watt 658 - 680 nm red 5 on each side of the board I'm gonna try some 395 nm monos and some 730 far red monos to see if they help any I have never tried them but anyways be back later to post the volts

Is this Amp meter on the dc side? What current does it show?

Voltage and current. The atreum 144.2 works great with 60w or 34.2v @1750ma or 1.75a
So you want to be CLOSE to those numbers when picking a power supply or "driver." If you get 10 boards, you would just multiply the amount of boards with the required recommended wattage/volts/current. In this case its 10x60w=600w power supply. you can run with less power and sometimes even more. But to simplify things, just choose boards within your budget. Once you figure out what you can afford, you can come on the forums and say "hey i want to buy X amount of boards, what power supply should i use?" You can always email the company as well and they will happily help you.

After that the install/setup is pretty straight forward. Dont let fear take over your mind, you got this.

Ok well let me ask this what kind of board and/or how many to light a 5x5 area.. I’m honestly gonna end up buying something tonight to get my feet wet and start building

25sq ft. is a pretty big space. You can space out ( 8 Atreum 144.2 boards to fit that, or even (6) 244.2s either setup will require 480w driver.

You can also do Samsung or Bridgelux Strips, check out this blog https://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux, Scroll down to 5x5 and see the different build options. You just need to get the strips and powersupply, the rest can be sourced locally or if you can, just get everything online.

Ok I checked it out looks interesting but I think I rather go the other route.. have you tried the strips
Where can I buy some boards at? Amazon or eBay?

Naah didn't even bother... I took a while before I used them, they were boxed up and all for the first few months...

Check the link I gave you, it will give you a break down on everything you need to know about the strips, from where to buy to power supply matching etc. Id go with either Atreum or HLG QB boards. If you go with strips, you cant go wrong with Bridgelux or Samsung. However I only have direct experience with Atreum.
