DIY Grow Lights with high-efficiency LED strips

Right now I’ve got 2700K, 3000K, 3500K, 4000K (limited) and 5000K in stock. Charts below illustrate their relative spectrum intensities:

i was thinking of using 4 3500k solstrips/solsinks in a 60cmx60cmx180cm tent and was wondering what driver i should use ? or if there are any better set up options

The HLG-185 should work if you don’t plan to run them at full power. Full power (50.8 W x 4 = 203.2 W )

have you checked his website if there is a shipping cost estimator?

australia wasnt on the shipping list for delivery

As someone who has been dealing with Chinese LED vendors for the better part of a year, be very wary of knock-off items such as these. There seems to be a whole sub-set of Alibaba vendors who seem to do nothing other than look for hot-selling items, grab some images from the original retailers website, figure out the unique search terms associated with the products, and post them on their own pages with a low-ball price. What you receive from them could be anything - including something that may have no resemblance to the item as pictured or specified. But by then, your money is in China, and returning a $100-200 order will be financially untenable. This is basically the business model for scores of Alibaba vendors, especially those promoting low or no minimum purchase amounts.

In this instance I know personally that this manufacturer has never produced authentic Quantum Boards. I also note the info on the LED brand used is listed as “Samsung/Epistar”. Since there’s no joint Samsung/Epistar branded LED chip, you can bet you’ll get Epistar diodes, at best. Caveat emptor.

Hi @casperdeigh, Australia delivery is now available and you can calculate shipping to AUS for any order you place in the shopping cart at SolStrip.com. The actual cost will depend on your location.

From my 2 yrs of dealings with Chinese vendors i’ve found that most clone devices are made in the same factory with the same parts. These factories are outsourced by us companies to acquire parts and and assemble. Then under cut the us company by continuing to manufacture them and sell directly. Now what you say is possible but there’s already other people that placed orders. You could wait to see what they say be4 you jump on it. Also one of the company’s has a 10 yr gold standard. That’s not easy to maintain with a greedy whiney self-entitled usa based consumer market.

Sure, anything is possible, except that you will receive an actual Quantum Board. Because that vendor never built them for HLG. So they are knock-offs at best, or completely fraudulent fakes most likely. I will let the others who just want to believe waste their money. I don’t have to wait and see, I’ve been there and done it. I just wanted to warn others since you seem intent on promoting a vendor you’ve got no experience with who is blatantly promoting counterfeit goods branded with a retailer they have no business relationship with.

Well obviously you only deal in an absolute way of thinking. The fact that others have placed oders and will give honest feed back matters nothing to you. If that’s not enough then nothing will be.

Hello everyone, here Is my solstrip build so far. I will use these for veg cycle. These have 3-5000k modules and 1 each of the 2700k and 3500k modules attached to each cookie sheet. I modified an old Xbox 360 power supply and then attached a boost converter and we are in business! I got some 19 gauge Cooke sheets and they seem to be doing just fine. I did put one solstrip backwards and the thermal tape I used was so strong that I couldn’t unattach the strip from the sheet. So I just left it there and wired in a thicker gauge wire to it. Seems to have not added that much resistance from the added length of wire… I have yet to add some hangers but I will borrow the method @Baudelaire used, which is drill holes in the 4 corners and use some sort of lace or string to hang them.

Btw I wired them all in parallel. I really like the solstrips because they have a lower voltage that is easier to achieve using the booster method than the cobs or even other quantum boards… I am only pushing 1 amp through these in the picture and they are still too bright to look at directly. I did a heat test at 10 amps for each sheet and they do get pretty hot. I may need to tape on some heat sinks to the backs when I start cranking up the power for mid veg cycle.

That’s a great idea with the Xbox power supply! Now you got me thinking if I can wire up my 1000w digital ballast some how.

Nice!
I am experimenting with converting a 1000w gold EVGA psu into a 12v dc power supply and boosting it up from there. But word of advice, don’t use these red boosters I’m using in my pictures. They can’t handle the instant on at high amps, and it fries the booster’s circuit board. The green boosters that are rated for 600w are pretty cheap on eBay and work much more nicely.

As of right now I’m experimenting with the chargery s1200 power supply. It can be driven to 24.3v and up to 50 amps. It costs about $240 on eBay and is one of the most efficient power supplies available. I figure it can push 25 solstrips to their max which is a lot of light…

That’s awesome and i’m not finding enough info on doing a retrofit for the hps. 1200w 4 240 is a steal, is there higher volt ranges avil? I’ve really got my heart set on these (till something better comes along lol)

There is the chargery s1500 for about $300. It can do up to 30v at 60 amps up to 1500w. That’s the highest I can find for power supplies of that quality. But for sol strips I believe 24v is as high as you want to be because of all the heat that it will generate at that level.

I was laughing my butt off when I first read this.

I am a curmudgeon, it is true, but I thought to myself, this is probably the first meaningful use for an Xbox that I have ever encountered.

I would not recommend you go over 24 volts per strip. Anything over that and you will be over driving the LED’s. You run the risk of thermal runaway and/or just having them not last very long at all.

Its also important to use a Constant Current (CC) type power supply. Anything else is a big risk for killing the strips prematurely.
