Can I drill additional holes into the strips, would fit my design better. Or is this whole strip something like a platine, which I may not destroy?

Im looking to get some of these to build a clone/seedling light that covers 2'x4'
What driver do you reccomend? Im going to get 4 strips at 22", I want to run 2 strips per driver

Thanks for posting this. Just wanted to confirm that this combo can dim to 0 even with older hlg-185h drivers

HurricaneX LED Controller, 80,-$US plus 0-10V PWM Extension for Meanwell HLG-Drivers 25,-$US

No wifi, but with display and half the price of a bluefish controller.
There are a few arduino related threads here but basically you just need a 0-10v pwm extension card because arduino is limited to 0-5v pwm dimming.
There are a few more commercial solutions(typhoon, supernova..) but it's hard to find their source-codes for their latest firmwares.
The most I found is outdated...

Yeah, but only with an additional relay as far as I know. ELG-Series dimms to 0 without relay but unfortunately lacks a bit in effiency by 2-3%.

I've been thinking about using LDD drivers for 8 1ft strips instead of one large driver for redundancy and more control like dimming per each channel. Plus I want to learn Arduino and create PWM dimming for it.

Here is my thinking, I would like to separate strips into 4 channels, 2 strips per channel and one LDD-350ma driver.
Each channel will have 44.2V (2x22.1v) @ 350ma well within range of LDD-350 driver (2 to 52V).

My question is this: how do I calculate the power supply for this setup? What output numbers I should look at?

The way I understand it is that I need a single output 44.2v (plus small overhead of 10% or so) lets say 48v
and for Amp I just add them together so 4 x .350 = 1.4am
(so instead of adding Volts if I would go with one large driver I'm adding Amps)

So the power supply should have at least these numbers: 48V and 1.4Amp

I was looking at these drivers:

* Mean Well LRS-75-48 (Single-OUT 48V 1.6A 76.8W 5-Pin) eff @91.5%
* Mean Well LRS-100-48 (Single-OUT 48V 2.3A 110.4W 7-Pin) eff @90%
* Mean Well NES-75-48
* Mean Well RS-75 Single-OUT 48V 1.6A 76.8W 5-Pin

Am I looking at this correctly? Will this drivers support 4 LDD-350 with 44.2v @350mA on each?
Also, does it matter if PSU has single output? Can I connect all 4 LDD to it? Or do I need separate output for each?

Nothing wrong with your calculations! But lacks a bit in effiency..(91,5% x 97%= 88,75% with the 1st. driver, 87,3% with the 2nd.), but I see no reason why your setup should not work.

You could also use a HLG-80H-C350, 91,5% or a ELG-75-350, 91%. The ELG series is dimmable to 0 but you would need a 0-10v pwm extension card to convert the 0-10v from the driver to the 0-5v from the arduiono.
There are a few threads about pwm dimming and arduinos. At least one is from the talented hobbyist and programmer @VegasWinner, maybe he could be helpful for your project because he already created an own arduino based pwm controller.

There are also the HLG drivers from HLG-320 and higher, which support 0-10V dimming and the HVG series (only for 230V and higher).

Yeah, I know, but he said it about the HLG-185 and the smaller ones are not upgraded to 0-100% dimming as far as I know.

I got some red 660's i want to drive, was looking at the LRS's but the efficiency is terrible.

You can dim the eln series to zero and the c2100b to zero doing that already. The system I use is a pwm to 0-10v converter for like $6 from ebay. It can dim up to four meanwell drivers easily. I also have the GrownGreen Controller I developed. New model has 12 individual addressable channels six for dimming six for relay controls. You can use other pwm controllers made for aquarium folks also or you can build my DIY six channel model for free your time money parts on github under avidlerner.

hi vegas,
I bought 6 of the ebay 660 nm you had linked to in the far red thread, whats the best driver to use?

Most american meanwell drivers dim to 50% regardless of what controller you use. You can control on off with a relay. Better to use an on off signal than pwm signal for relays.

Those have an Vf of like 12v and want 700mA current flow so you can use an lpc35 from meanwell
Click to expand...
Thanks for the reply, I thought the Vf was 6 to 8 volts and current was 1000ma? anyway that would only give me 7 watts apiece, is that how you are running them?
