@Budbrother what driver are you running that at i can use a little help and infor before ordering and building i live in the Caribbean and they just recently passed the law for 14 plants per adult ive been researching price cost and i fell into the EB gen2 what i’ve re search its alot confusing im getting messages im not very savy with electrical work but this is what i came up with id like to build a spine build 4X4 46’inch 1’inch profile bars from heatsink usa that runs $9.71 and running total of 10 EB gen 2 strips on an X2 HLG240c1050a 10 bars 20 strips total ? or should i do a total of 20 bars on x4 HLG240c1050a they are all auto flowers trying to squish them under 4x4 or 5x5 ps /// x2 driver will be connected by one powercord each driver run 10 strips each if i plan on running 20 bars IIIIIIIIIIOaOb drivers bOaOIIIIIIIIII
He is running fixtures with 14 strips on hlg-185h-c700 drivers on aluminum plate.
I swear this lighting DIY is so confusing driver’s
Only had it running about a week but I can tell you so far it puts my 4 rspecs to shame as far as coverage and brightness. Even lighting pretty much all the way through
Also thank you it looks beastly!, ive already been contemplating a 2nd one if my buddy buys my 4 rspecs. Although I wouldn’t mind trying out the syncedled raging kush also.
I’m not sure what you’re confused about. These are all constant current drivers in question. They have an output current and and a voltage range to where they will operate at nameplate current. If using any of them in series configuration you simply see how many modules will fit within the acceptable output voltage range. A 200 watt driver at 700ma will have higher acceptable voltage than a 200 watt driver at 1050ma, so more strips will fit in series connected 700ma driver.
Running eb gen2, the strips will run cooler and more efficiently at 700ma than 1050ma. So in example above, Budbrother spent a little mord money to have a more efficient light than the configurations you had been considering prior.
@dbrn32 hey man long time. Thanks for all your advice wish i had everyone at fungertips this year it was a soletary one… Got to say bro the 4 1120 f series gen 3 sammy in 4k u helppped me build have performed phenomenally the 600 v2 rspecs definatley were a good. Buy as well i have gone through like 6 phones since then all pictures lost but lots and lots of joints smoked thanks to you i still have some from right when i got banned not to mention intermiddent grows got a nice opp cummin up now. Of course ny phones cracked and this is all i can immage …no i didnt set this up for yall right on time for ban to lift its for meeeill try and get another phone there its another remote plot ill make a new thread just wanted tobsee how many posts u were up to
Glad to hear lights are performing well.
So one of my 100 watt Cob lights just started to flicker a bit which is kickstarting my plans for a DIY build into gear a bit quicker than expected. I know I want to do a light with COBs and that if my $300-400 budget allows I would really like to get about 800 watts with a dimmer in the light. I’m working in a 4ftx4ft tent right now but am planning on fairly soon stepping up to a slightly bigger tent so I am hoping that the light I build will be able to work in the tent I have now and in the larger tent. To do that I wasn’t sure if I should be planning on building one large 800watt light or 2 400 watt lights that I can space out with a little distance between them? Is that kind of lighting possible with the budget that I have? I am honestly extremely new to all the DIY I’ve been trying to keep up with the threads and do some research on my own but I just am not sure how to price out all the individual pieces that I need to replace one of the DIY kits that are sold it just kind of hasn’t fully sank in how to figure out exactly what is needed and how to find the prices for them. If @dbrn32 or anyone else with a bit of DIY experience and COB experience could help me out a bit I’d really appreciate it. I’m really looking forward to this next project it just has a little more urgency now that one of my other lights is goin out.
It’s going to cost about about $1 per watt to build from scratch using the higher end components. Sometimes a little more or less depending on what exact components you use and where you get them. There are discount codes, tariffs, shipping charges and a whole host of things that can sway pricing.
Outside of pricing, your biggest hurdle will developing a light that will work now but also fit well into your future plans. When you expand, how big will you be expanding to?
So probably not hitting 800 watts with that budget if I’m going with the higher end components then. How bad would it be for the light to go with say the previous gen of COBs to try to keep price down to get wattage up? I’m planning on expanding into either a 5ftx5ft or maybe a 4ftx8ft. I need more room to be able to move around my plants during flower I have a bad back and its difficult for me to try to bend and maneuver through the smaller tent.
I guess depends on what is available in previous generations. Been a little while since I shopped for them, but cobkits had some deals on earlier citizen modules.
As long as you don’t know of any big draw backs to going with those it might be worth looking into for me. The lights that I have in my tent right now all run on Citizen COBs and I’ve been pretty happy with them but just like now I had bought the Citizen instead of the Cree chip lights cause I couldn’t afford the high end ones haha. Budget always seems to come back to bite me. This is going to be an awesome project though I think that I’ll be able to with help build a much better light than I’d be able to actually afford. I’ll just have to put in the extra elbow grease and you know brain effort.
If you cab run 52v cobs the Luminous are worth looking at too. The last time i ordered bulk pin sinks I had them dilled and tapped for citizen 1818, Luminous cxm-22, and bridgelux vero 29
I’ve heard alot of good things about the vero 29 chips. I’m not sure how many others have been using the Citizen ones but like I said I’ve had good results with them so far I just think I need more light to be able to really get my plants to where they need to be they still come out a bit fluffy right now. With any of those COBs what would be the most in terms of wattage you think I could get in terms of the budget? Am I looking closer to just one 400 watt light? I think I can make that work if I really need to because like I said I have 4 100 watt COB lights that have Citizen chips but 1 is on its way out. So if I needed to instead of moving them out of the tent I could try to position them where needed to supplement where its needed in the tent until I can afford to build another one. I can’t tell you how much I appreciate your help man I wouldn’t be able to get through this build without people like you.
No problem, that’s why we’re here!
Something that may be worth looking into, is making 300 watt light bars. You may be able to build one now, then additional later. If you can find large enough heatsinks the vero 29 and larger citizen cobs are capable of running 100 watts per cov and maintaining decent efficiency. Would be like a knock off of timber 3VL. One bar for 2x4, two bars for 4x4, 3 bars for 5x5.
That honestly looks like a great option especially for my budget. Is it harder to find the larger heatsinks for the Vero 29 chips or for the larger Citizen chips depending on which ones I can find cheapest? I feel like I can already see this light coming together haha
I had to order from China on alibaba. That was some time ago though. You would be looking for something like 125mm square sink with splayed pins or larger. They may be available here somewhere in small quantities.
