My 8 solstrip DIY light

This is my first DIY LED build and there's not much talk about these lights on IC so felt I should share the fun i've had recently. They are basically QBs in a strip running the same high efficiency samsung diodes.

As you see here, this rig is 99% finished, still needs a couple more bolts pinning her stiffer and final mounting wire and carabiners etc and thread lock on all the bolts then a final final wipe down.

8 X2 Solstrips (original one sided connector models) on a 1" x 1.5" Aluminium frame, bolted onto the 1.5" side. The heat sinks the strips are stuck to have a 1" space for mounting at each end leaving 0.5" free of the 1.5" side of the ally. On this driver (HLG 240 24a) the strips can only pull about 270 maximum watts between them I think so these strips can only pull around 33 watts tops and even with the dimmer all the way down it's insanely bright..

Pics say 1000 words..



You can wire these lot's of simpler ways than I have I wanted to try and hide them as much as possible so I bolted a 1.5x1.5x1.5cm U rail to the side with all the power connectors and then got an L shaped piece to go on top and hide the wires, which required tapping screw holes to mount. I used rubber grommets to protect against any wear on the wires as there would have been lots without them.






^ Wieland quick connectors for the power lead so the light can be really easily moved around if needs be. They're a bit expensive but imo totally worth it. I was also tempted to wire in a digital multimeter with a display on the top so I could see what the unit was drawing and how dimmed I had the LEDs but there was no point as running 8 X2s on this driver could only be within really safe tolerances for the strips, they can't be overrun on a 33 watts tops setup. I did a 7.5 cm gap in between strips, 10.5cm mounting hole to mounting hole, which is a bit close compared to how some have done theirs, I've got more strips on a lower wattage per unit for best efficiency and hopefully longest lives.





I used a mix of spectrums as you can see.. 4 x 3.5k, 2 x 2.7k and 2 x 5k for a total around 3.6K.. This runs very cool and is very bright. This is aimed at flowering and I want to make another couple smaller 6 strip vegging lights. This will do for a 3' x 4'to 4' x 4' area me thinks.

Best vibes brothers and sisters!

Still nothing huh? If I log out I can't see them either but they're only in jpg and I can see them here and in my album..

Why TECHNOLOGY!!!!!! WHY!!? (falls to knees dramatically holding a furby)

I'll figure it out, somehow........ so far just a lot of dots.. hmmm

Edit: Boom let there be light.. uploaded them into a private album, quick change to none private and hey presto-- itsa light amada by me (no Italglish racism or Nintendo copyright infringement intended)

Discovered, again , that i'm safer blacksmithing steel at 1800 degrees than trying to tame the fiery tongue of a dreaded soldering iron lol, the wagos were a dream. Also I don't know why I went for that distribution of strips but I can change it whenever I want and swap them around... thatsa bella!

ciao

If this is going to be used for veg and bloom I suggest moving the 5K to the middle with a 3.5 inbetween then the rest on a separate o/o switch

Heya PF!

Good call yeah I kind of wish it had been a 9 strip light that could be flipped to bluer or redder for veg/bloom.. That might be a later version..

This is just for flowering for now but the imbalance of colours is a bit annoying. I might swap out the 5ks and just do alternating 2.7 and 3.5s.. I kind of wanted a little extra blue in there but oh decisions decisions lol. I was thinking like with the sun going from bluer to redder at high noon to bluer again through the day I might get away with this spread but I'm not sure if that logic works in a grow box..

I 'm just glad it's over and I can hoover all of the aluminium shards out of the carpet now.. Ha not been totally popular with the ladies lately, well the human ones anyway..

Any criticisms and advice on how to do it better is definitely welcome as i'll probably be making a few more of these.

I cant wait for this one, pulling up a chair...

I wish people had some Par results of these kind of lights vs quantum boards... I know it would be far more evenly spread than something like a HLG 550 4 quantum board setup but maybe lower numbers overall.... Which fixture height could fix anyway.. We shall see

I would run the bars the opposite way to get more coverage

I know, I don't think the QBs distribute light all that evenly but i've not seen any data yet on them.. Lot's of people saying that more strips run at a lower wattage allows the plants to practically touch them and still be really happy.

I think since fluence have found a similar bars of LED lights system to be the most effective with all their r&d then strips might be better.

Nice thinking yeah my space is a tight 3x2 atm so i'll see no loss but in larger spaces with multiple rigs then that would make sense to send more light out laterally from a longer thinner light source if that makes any sense and I understood you correctly

I'm looking into 800 chip boards now {Basically something like a quantum board 800}.... They are like 1'x3'. Super cheap when you order from factory...

It would be pretty expensive to get the 4' 2 row strip style lights, and run them low wattage\high efficiency and fill in the footprint.. I think its smarter to just run them high wattage and get the umol out of them\footprint out of them.... but..... It would be nice to literally make a wall of lights and run them low power\high efficiency like the 800 chip boards...

I was looking at SGS Vertical systems on youtube thats what gave me the idea\reminder. They have the plants touching the lights almost..... stacked 4 shelves high... Running the lights dimmed low wattage\high efficiency.

https://www.ledgrowlightsdepot.com/c...led-grow-light

I dig their style..

They dont even use heatsinks either which if anything I'll take that idea, and just use plain sheets of aluminum to save the majority cost of these strip lights if i do go for the 4' strips instead.....Especially if you run them high efficiency style with more strips.
