im having a play with some strips on a budget build ,is it possible to use an lrs 48v driver turned down to 43v to power 39v bridgelux gen 2 strips?

i have 10 strips connected currently on a 350 model & its just doing some strobe type thing lol -_*

usually use hlg & elg series drivers :weed:

That's it's hiccup mode. If it's super quick strobing it's not hiccup. The hiccup is on and off every few seconds. That is an alert to continue to turn the voltage potentiometer down further until it comes on solid. I'd you turn it all the way down and it doesn't stop hiccup mode, it's not going to work.

over voltage 43 volts min on that driver max 52v and strip voltage range is
  • Voltage - Forward (Vf) (Typ):19.5V ~ 39V on your strips

Here is twelve eb gen 2 strips for one lrs350-36. Voltage max is 39,4v and after that u get safe mode and power goes off. I built new supercheap 36x eb gen 2 light and with these drivers you can really push your budget down. I give them 700ma so no need for heatsink and total cost was like 550 euros.

Maybe look at XLG range drivers. Though the highest is 240w , they do 150s too.

They are more expensive than LRS but much cheaper than HLG or ELG.

im connected in parallel , it shouldnt be over voltage really?

i run elg 240 48v with gen 1 strips what are 44v without adjusting the voltage & its been fine for years

ok i see , it was all the way down to start so looks like its not gonna work , ill save these lrs for some kinda 48v project & pick up some elg or hlg series for these gen2

i presume a bunch of 24v 2700k/5000k bridgelux strips paired up in series for 48v then wired in parrallel will run ok on these lrs drivers?

Yah looks like the voltage range just isn't quite wide enough to work with those strips. If you could wire like a 3-5v mono in series with each one, you could use it though. Maybe a blue and a red at 3V each to give you that extra spectrum peak? That extra 6V would get you to 45-46V. Maybe put one in front of the strip and one after.

where would be the best place to source some monos, do you have any model numbers i could search for?

would it just be a case of plugging 1 into the end of ea strip? may give that a try tbh could add some mono reds or summat:blsmoke:



like a pair of these in series with ea strip? is there any that come with tails to make hook up easier?
Ya but those are bare diodes. you'd want them put onto a PCB star with solder points.
Yeah you'd just put one on each end of the strip, neg from first mono to pos of strip, and neg of strip to pos of last mono. Then to wire in parallel, you'd connect drivers positive to the first monos pos, and the neg to the last mono neg.

ok cool that makes sense in my head, who does monos mounted on little boards ready to hook up? i can solder if i have to but tails are preferable

i have 30 of these strips ,would need 60 monos but dont wanna go crazy on spend as the gen1 setups perform great for me with nothing added

Cutter definitely can hook you up, but I'm trying to source from the UK for you. That's where you're at, right?

yea im in the uk , was having a look on cutter earlier but always get lost on their site lol

may pick up 3 elg 240 42 as budget option & swap out to hlg 320 42 when its flower time.

i was gonna pick up the 350 36 ver of the lrs power supply but digikey were out of stock & wasnt sure about running it turnt up wouldnt that make it 39v x 9.7a - 378 watts? (no way to adjust current on lrs) / 9.7amp divided by 10 strips? i usually run them @ 700ma with nice results :peace:

XLGs are 30% cheaper in uk , half the size, half the weight, same efficiency

Currents adjusted by adding or subtracting strips. ;)

i had been told this by a pal whos into electronics but i read different on here some years ago when i built my first led setup,

i always divided the drivers output by .7amp to get a ruff guide to how many strips to run on it in parallel ,

i thought if you ran 5 strips on a 7amp driver for example that they would pull 1.4amp ea?

https://www.tme.eu/en/details/xlg-240-h-a/led-power-supplies/mean-well/ are these xlg a more recent addition to their product line, & is this the correct model? :joint:

RapidLED.com has everything you could need but I dunno how much shipping would Be, but probably bit much because they can fit in a tiny parcel.
