Would one of these COB led be enough for a 5 x 5 grow tent?

Its hard to believe it is the wattage it says, normally it will say the true wattage somewhere in the small print but I cant see it.
So its difficult to say. But I would say its not close to that wattage based on the chips used. That said you wouldn't need that sort of real wattage to light a 5x5 anyhow.

Just beware there are COBs and there are COBs, unfortunately since COBs really made a name in the growing world thanks to folk on here and other forums and youtube everyone jumped on the bandwagon and started knocking out "cob lights" left and right.

The word COB sells, like tits in a lads mag, but it is not the COB that is special, its the efficiency of the light, something like a creecxb3590 , which is kind of where it all started are very efficient, but they are also white light with a great spectrum.

Epistar are not efficient in comparison and they are still using targeted spectrums with reds and blue diodes.

EDIT.. I found the info on the coverage and it says that light will cover 2ft x 1.5ft in bloom, so to answer your question NO. when you take that coverage into account its actually really poor value for money.

EDIT2 somehow I missed the real wattage on the page. It's 680w. Now take that and consider the above statement on coverage and those two things do not add up at all. A 680w light that only covers 2ft x 1.5ft that is really really bad, it also says it has a lumen output of 30000, I know lumens are a poor measure but shit that's terrible, possibly the least efficient light I have ever seen. I mean even a 600w hps puts out 90000 lumens, this light uses more power to create a 3rd.. STAY WELL CLEAR!!

P.S sorry for waffling on, I couldn't be bothered to delete my post and rewrite it... :oops:

That was the spec on aliexpress. Your above spec seems more likely. Although they missed out the bit which says actual coverage for flower and veg which is a bit suspicious.

But your specs say its 545w which given the chips they are using isn't enough to light up a 5x5 for flowering, just basing that on what I know the very best efficiency can do such as HLG 550 or HLG 600 quantum board set ups and epistar are bottom of the pile for efficiency so wont come close.

I can appreciate wanting to get a bargain but if you had to buy two of those to light up a 5x5 then its not really a good deal and a better option would be to invest more and buy a HLG 600 which will actually deliver what it promises.

EDIT, I agree with ANC in that you will probably be able to light up a 3x3-4x4 but there is a huge gap between a 4x4 and 5x5 space.

Look elsewhere, any vendor that calls a ~600w light "3600 watts" is not one you want to do business with, regardless of what claims they lie about in their spec sheets. You need a minimum of 750w of actual output with COB tech (30w/sq./ft.) to cover that space and that needs to be spread out enough to physically cover the space. e.g. a single 750w single fixture say 30x30" is not going to cover the space well enough. Something like 3 our 4 of these could be spread out to cover the space well.

That is what I refer to as a Cobob (kebab play). It’s a chip on board on board. Basically each “cob”. Is several single diodes surface soldered to a chip, and then several of those mounted on a chip.

They are very inefficient. You would do better doing a DIY job if you’re up for it. Use some vero29s.

Don’t trust any light that has 3200w or any number followed by a w. It’s just a model number made to look like a wattage. They may work, but they do not last long at all. A good DIY will last years.

So would I need on HLG600 or 2?

DIY would arose a lot of suspicion with my housemates.... I am just looking for the best premade low cost LEDS for now and I think from all the recent feedback from the pros quantum boards are the cheapest most efficient LEDS at this point in time since they jacked up the cree prices....
