The driver wires to COBS are to short to do it the same as video.
are the driver wires to cob a standard length?

I'm currently going through a warranty claim with Mars ...had the panel for almost exactly a year and 10 diodes basically melted on me.... I've heard if warranty claims are within a year they will send a shipping label to send for repairs....we'll see how this goes.

good luck man. you can make it a Cree light just checkout @Growmau5 he has a video on how to upgrade that light so you don't have to smash it like I did one of my Mars II crap.

Its unlikely any wire length is going to work for everyone, adding wires(wirelength) is not a difficult task

I have a mars hydro 300w (actually about 150w according to my special plug) that I brought second hand off ebay for £50 and it has worked fine for about 8 months now on a 18/6 schedule.
Cant really comment on the grow yet as it is my first and I stumped the growth seriously by over feeding at the start, now though the growth has exploded, I guess the girl got to the stage where my newbie mistakes (over feeding) have less effect.
Initially started with 2 girls but I don't think there was enough light for it in the 15ltr smart pots I am using so I just went to one, again this has probably helped with the growth also.
I would like to upgrade, or at least get a second light as I now have the dilemma of switching to flower but I want to clone also so need two light schedules for this, being as it is summer I could probably stick a clone on the window ledge but would rather not as the tent is a nice controlled environment and is easily tall enough to keep the girl vegging for another few weeks is needed.
To that end could anyone make any recommendations please?, I don't have a great deal of experience in lights and started with the mars LED straight away so I have nothing to compare it to, and as everyone knows a lot of videos on lights are often fake. The MAU5-IV looks interesting, what sort of area would that cover and does anyone have any grow diaries using it please?. I am also fairly poor so looking for best bang per buck, I could probably stretch to the MAU5-IV but not anymore than that.
If anyone has a must read then please linky linky it also, thanks.

Hey guys i am changing my diy setup a little bit. I am now doing 4 vero29 4000k per heatsink. I will be using 42" 5.888" profile. I will be putting in a 140mm fan for safety measures. I am having a hard time picking a driver, which one of these two would you go with. hlg 240h c1400b or hlg 240h c1750? I am trying to achieve 250watts per 4 cobs on the 42" heatsink. What size wire would you recommend to work with the vero29s? i've heard mixed reviews, some say 14guage some say 18 is fine. My question is which would would you use and solid or stranded?
you might not be able to run 4 vero29s on the hlg-240H-c1750 at 1750ma. 4*38 = 152
, Voltage range is 71 - 143V. The driver will probably lower the current as it hits the voltage max. maybe somebody with vero29s knows.
18 gauge wire is fine, I prefer stranded for flexibility. make sure the wire insulation is rated to at least 300volts.

Thanks for pointing that out PB. How about the hlg 240h c1050b? I'll get stranded 18awg insulated for 300v. What about the solder, what do you recommend or like to use with a 60w soldering pen?
I'm having a hard time understanding the numbers on led drivers. I know on meanwell 240h is the watts it'll consume, c is for constant current, what does the 1050, 1400, 1750 mean?

If all Burple lights grow like my Hydroponics Hut Pro-Grow (which I thought had a great spectrum for that theory), then I can't believe the Burple thing ever lasted a day in the pot growing world. Seriously! Ridiculously poor bud formation & very little.
The Amare must've pulled 5x more of nice ass bud.
White light all day for growing cannabis.
I feel so sorry for those using Burple & thinking it's ok.
So glad I did that comparison.
I feel like pulling a @REALSTYLES on it like he did his Mars & it hasn't blown out or anything. Just so disappointed w/ it in comparison to just about any possible light source.
I will e-mail them & ask to return it. I just don't see any possible use for it. Vegged well but I don't think it will in flower mode to get full use out of it.
Did that test based on the claims they made on their site. Early in learning about led for growing I wanted to believe them & the RGB theories in being superior spectrums.
If your new to led buy a white one!

They think of these LEDs? 2 would be sufficient to 100x100-200cm?

What are peoples thoughts on this one http://www.ebay.co.uk/itm/Populargrow-Full-spectrum-400w-COB-led-grow-light-Flower-Hydroponic-Systems-Lamp-/262382966431?hash=item3d173e569f:g:XnoAAOSwuAVWxmyR
I found a thread on it here https://www.rollitup.org/t/im-testin-seed-to-harvest-with-this-pretty-neat-cob-led-from-the-ama-if-anyone-is-interested-400w.897404/
But it looks like it just turned into a pissing contest, you can see that there are different colors on the cob and not pure white but according to their light spectrum specs this is "similar to the spectrum of CREE CXA& CXB 3070 3000K".
I have minimal knowledge of COB's (just what I have gathered from others posts) just putting it out there, any help appreciated as I would like to buy a second light.
Some people keep saying burple, I am guessing this is when it is painted purple?. This one produces a purple-ish light but I think this is from the purple diodes and not a colored lens?.

I guess I'm going to assume member: BillyGreen, killed his plants. he was the guy with the two K3's and AT200, posted up to a week in flower I think.
its really depends on your budget, but if I had other options I would look in to them besides these types of cobs.

Hi SoOLED, thanks for the response, I am not sure what happened to his plants, I tried posting for an update but the thread is locked.
I am not to well off, I could probably go to £300 but in honesty I am just an amateur grower so it really needs to be justified. I would prefer to go no more than £200 and only ever plan on growing no more than 2 plants at a time preferably auto-flowers.

That seems great, but can I hang the COBs individually or do I need to build the metal frame to hold the lights?
Hello guys,
I found some leds available locally. It's like u$16 free shipping, and as it is a local supplier import fees don't apply and delivery time is 5days....
Not thinking on huge grows with these LEDs, but I want to build one MVP(minimum viable product) to test and learn... Don't wanna buy a vero or cxb and make a huge mistake and burn it....
http://www.zemeled.com/en/pro_detail.asp?idd=49&ids=4&SortID=21&id=21&ord=100&f_1=4
I'm a micro/stealth 1 single plant grower, so my idea is to make one light to 1,3sqft.... If it works I'll just build one more to a fiend of mine, then I would buy the vero/cxb and go for the real deal
Considering delivery time and no import taxes, I think it's worth the shot.
Any inputs/advices?
Cheers

A core truth that keeps getting restated in different ways throughout this thread is that unless you have DIY chops or a minimum budget, it doesn't actually make sense to go with LEDs. That budget threshold is dropping quickly, however.
I know that's not what anybody wants to hear, but for right now it's true. £99 buys a nice HID or a pants led.
