Hello there,
I have built a 1st wave of LED prototypes & am working on my second, last time I made them with LED strip rolls & this time I'll be using Samsung's Horticulture linear LED modules:
This is the data sheet on them:
https://cdn.samsung.com/led/file/resour ... ev.1.0.pdf
& here are the two lengths, Samsung makes both a 1ft and 2ft varient:
https://www.samsung.com/led/lighting/le ... re-linear/
My idea is to make 3 different Light fixture types:
1) 50w LED using x2 the 1ft Samsung linear
2) 100w LED using x2 the 2ft Samsung linear
3) 150w LED using x2 the 2ft + x2 the 1ft Samsung linear
For my last set of LEDs I chose the MeanWell HLG series drivers, example: HLG-240H-24A since the LED strip roll lights were 24Volt LEDs
Which driver should I go with for the 150w LED (example 3 above) that mixes the 1" & 2" LED modules, since the 2" has a input Voltage of 43.1 V & the 1" has a input Voltage of 21.5 V
I think I'll reach out to MeanWell as well, since they are really good @ responding & I'll post the results here
Cheers,

Can some1 help pick the Driver for this LED build?
Excuse the slow reply, & thank you all for the replies. I just drew up these pictures of how I envision the LEDs looking like.
Decided that, for the previously mentionned example (3), using x6 of the 1ft variant is better than x4 2ft + x2 1ft
I just got to looking for a supplier for the LEDs & the power supplies, glad to have made this post & to have checked up on LEDGardener forums prior to making the purchases
This is the dimmer (Potentiometer) I am looking into using:
& I'll try uploading photos of the diagrams that I just drew up:
I am making a 3 feet long light fixture.. I have 3D-designed it and am gearing up to get ready to 3D print it. Redesigning this light fixture has already happened many times & I have made my 1st batches of prototypes... I don't mean to sound annoying but I seriously do not wish to fully redesign the Light fixtures just based on that strip's limit.
Can I go with the original plan of a 2ft strip + a 1ft strip? The whole idea is to have x2 3foot bars of lights spaced out to allow the potential for sunlight to easily pass through & spread the diodes as much as possible.
Is there another light strip that you'd recommend? I really want to try working with the Samsung LM301H & LM301H-one series

Working voltage for insulation: 59 Vdc Rating (SELV)
Page 16 of the Datasheets...
You could extrapolate that the 1ft strip "Max parallel" would actually be 4 bars not 2, the equivalent of two (2) 2ft bars or 4 linear ft. The assumption is that the electrical traces (characteristics) are the same for 1ft and 2ft bars. So parallel wired you could possibly daisy chain three (3) 1ft bars, but not six (6).
The other option as mentioned is Series Wired (the Datasheet info shows eight (8) linear ft wired can be wired in Series), but it exceeds the SELV (low voltage) rating of the LED Strip; the mix of 1ft and 2ft strips or six (6) 1ft strips wired in series requiring a "Series Driver" with ~ 155 watts, ~ 129.2 Vf and ~ 1200 mA.
