Thanks heat problem and smell is sorted, removed heatsink tape was burned and add thermal paste and sorted, pumped them up to 37.8v and no problem, heatsinks get hot when fans are off but when on they keep real nice and cool
I have a LSR-150f-24 its rated 154w [email protected] they arent constant current drivers. Its adjustable 21.6vdc to 28.8vdc the rating is [email protected] if you go above that. Say 26.5vdc the current should drop to keep the output at 150-154w I dont think the current stays at 6.5a bc if it did it would put out 172.25w which isnt what the driver is rated for. So I'm pretty sure the current drops to 5.811A but you're saying yours puts out 9amp at no matter the voltage setting? I'm assuming you have the LRS-350-36 puts out 9.7A adjustable from 32.4vdc to 39.6vdc doesnt it put out 9.7A @ 36.01vdc give or take. And above that the current lowers to maintain the 350w. So at 38.5vdc the current would only be 9.09A wouldnt it? Or is the driver that far underrated and pushed 39.6vdc @9.7A for 384.12w can you confirm the current doesnt drop? Just curious bc I have the LSR150-24 I was gonna use for some H inFlux_L06 strips. But if it doesnt lower the current I dont wanna use it. Bc itll push the strips super hard.
The usable amps should drop when the voltage goes up yes for sure, but for my 4 veros i only need 8.4amps about at 37.6v so that should be reachable, i did not test the amperage draw again but it was pulling around there on that voltage when i tested previously. Thanks
Something isnt right. With the voltage of the driver set exactly at 36.0vdc the driver should push its max amperage 9.7amps over 4 cobs wired in parallel I'm assuming. Each cob should get 2425mA at 36v for 87.3w how are you only getting 8.4A at 37.6vdc that's only 315.84w the driver doesnt put out 315w its gonna push 350w at 37.6vdc you should be right at 9.308A not 8.4A
The driver does not push out its max because it has it to push out, it only gives out what is needed by the lights, and the lights only need 8.4A at 37.6v, if they needed more lets say 10A then the driver would give out its max
I always thought LSR were set to push the full amperage at their rated voltage. No matter what. Like the lrs350 is rated at 36.0vdc and 9.701A
Yes, i tested them on a lower voltage aswell i think it was like 35.5v and the 4 veros where pulling like 3A if i remember right, i have a a 48v LRS350 aswell with 3 samsung led strips on them and they are also not pulling the full amperage
That's the reason I had been buying HLG series. Bc I thought the LRS series pushed the max all the time. And here all this time I couldve saved a bunch of money lol.
Yeah that was what i was thinking aswell but then i thought rite id buy these to test and worked out good, i think only problem is when you thermal runaway then the item will pull all the amps it can get and nothing limiting it but that can happen when something fails in the component(light) you are using
Might be able to put a resistor in series with the cobs to balance it. To stop thermal runaway. I'm not 100% on that.
Thhat is correct yes,
Hi, yes there is something you can add, i did not go for that option though, will add it maybe later on, but yeah im not expert lol, you can possibly ask some of the wise guys on carbonite that work with this stuff a lot one guy told me what i could add but that wouldnt work for me because my cobs amps that they use are to high up
Yeah big difference in price. I got the LRS150 for 18.99 shipped to my door. And the hlg150 is 50ish shipped.
You could probably find a 3amp DC inline fuse. If you're running at 2.5A and something happens that causes thermal runaway and the amperage starts to rise. And say your cons max out 4500mA just a guess idk what the veros are rated for. But put a 3amp dc fuse in series on the positive side and if they start pulling too much it will pop the fuse and in turn cut the DC+ side of the feed to the cob.
My problem was budget lol so i had to choose smaller light or the LRS
Souns like something that can work yes
I'm all about budget man. I've built 2 Samsung F Series Gen 3 strip lights. With single row f562b strips. The second light has 7 strips. Spaced out. And I got a great deal on the H inFlux_L06's so I figured why not put em inbetween the F series strips. So that's what I'm doing. And I still need a driver. I've had the LRS for awhile and nvr used it. Bc I thought that about the amperage on them. Pushing max all the time. So I never used it. But now that I know that I can use it. So now I get use out of it. And save money by not having to buy another HLG.
Yeah definately save some money on that, dont get me wrong on the long run the HLG are the way to go probably but on a budget LRS is it for me
