Any opinion on this new Cirrus 10 COB light - 1000 watt?

tylerkewl said:

Oh many of us would be.. But at the price I got it for QBs are about 3 to 4 times the cost...

I thought you paid $400
Not even twice the price for a HLG 600h from growers lights and that's based on the discounted price you paid, on the advertised price QBs are cheaper.
Plus the QB coverage is far better, efficiency is far better, spectrum is far better, PPF is far better. All with the reduced cost of running less wattage.

Not hating on what you have, but your statement is false.

But its over 1000 uuumols so it must be good.........

I just did, 4.18A at 250V, 1045watts

And there you go. So HID typically 75/1 efficiency. If they aren't lying. 99/1 for their led..They didn't lie about the draw... I totally agree 999$ is way more than I would pay.. If I was going to dump that sorta cash I'd build my own. If I had to pick between the Cirrus and HID. Cost not being a factor..At this point I'm really leaning towards the Cirrus. And from what I've seen there are going to be plenty of people out there who are going to be in a similar situation.

I just did a quick google search for the 1000 watt cirrus, and most of the results I got put this light in the $700 to $1000 range.

Try being realistic when making comparisons. It might help your case.

I guess I'm one of the roaches or trolls you referred to earlier?

700 to 1000 is correct...But we all know there is about 300bucks in parts at the most... My whole point is att the same price or just slightly higher than a gav..Which I paid..Not what retailers are asking..It's an option....I suspect they are wholesaling for no more than $500

Seriously I have never seen a remotler positive thing on this board for anything other than HLG,CobKits,Or build your own with one of the high end chips...Has anyone said hay wait..1000 bucks is way high but half or less it is an ok Deal.. Nope just that it's a waste and some even said they wouldn't use one for free..I don't want to pick a fight. I have seen this all before here..And Wells it's almost worst than I expected...

Then you haven't read much on these forums. People are using and endorsing Fluence, Timber, PLC, Amare, and more. Not sure why you're offended that people don't think this Cirrus is a good deal, even at half price. In many people's opinion, $500 will always be too much to spend on a fixture for which insufficient testing has been published. Furthermore, the design is fundamentally flawed; the footprint isn't really any better than that of an HPS, so say hello to a hotspot in the middle and drastic fall-off of intensity on the perimeter. Whoever designed this has failed to comprehend one of the primary advantages of LED: uniformity.

We aren't being critical because we want to be mean to you or make you feel bad about your light, but we aren't going to withhold honest opinions to spare your feelings either.

Yikes .... Somebody said was supposed to be a " white light " .

It looks like it throws hot spots and targets only what is directly under.

Compared to the old blue and red it has a much whiter hue with the naked eye..I expected total purple.. My phone took even worse pictures.. They have some pretty huge optics over the cobs. But
Opinions??

I would see if you can take that whole bottom panel off, it looks like that would increase your spread. But I dont have the light in front of me, and really cant tell if that's a feasible option. Just from looking at it though.

Fricken Soo funny..I was just thinking about doing that..I have an angled ceiling anyways..So it just makes sense to spread it out different... Possibly even recess the individual cobs...But from the looks of it its pretty modular inside.. eache cob has it's own individual heatsink and fan... I won't be home for a few days but I'm going to look into that.

Thats because most people here understand and value efficiency and arent as focused on capital cost. At the current time this light is just another black box with unknown components and unknown efficiency and unknown lumen maintenance. Theres a reason none of these companies give real specs on these lights. Who would buy a light in 2018 advertised at 1.2-1.4 umol/J with no LM80 data? At some point those lights arent a bargain at *any* price esp when people are literally giving away SE HPS on craigslist

People will just about pay you avactualy to remove most of their crap now days. Anyways I'm going to crack this thing open in the next few days. We shall see just exactly what chip is inside. ImI guessing a 100w Luna from flip chip...That's the manufacturer they claim.

Take lots of pictures, I want to see how possible it is to take off the lenses.

now were getting somewhere! lets see inside of her

I would add BC Blondes and ChilLED to that list.

for sure

I don't understand how it could be a Luna series chip from Flip Chip Opto since none of the Luna chips run on AC. There's no driver in the Cirrus light.

Just an observation I made tonight. In our 4x8 flower tent, the Cirrus 1k; in the 4x4 veg tent my 170w cob watercooled light. Leave all the tent doors open and turn on both lights, The cob lights fill the garage with waaaay more light than the Cirrus.

i guess we will see something like that



driverless means: cheapest version to drive this spectrum ~ 1800K / (i guess) not dimmable - and so they are not able to drive a flip-chip efficiently.

It is ways better to buy these red phosphor chips in a 100W version with Vf 30-36VDC / If ~3000mA ($ 8,-)
Buying 1 chip / sqm² and driving a 100W chip @ 30% of max. load with a quality driver like
Mean Well on a selfmade fixture can cost you something like 400,-$ (ie. 30x100W chip + 3x HLG320)

Red phosphor chips with 1800K and lower - always show higher temp. on the LES because their silicone is much denser than a coolwhite phosphor.
@ max. load like cirrus 1K they often show degraded silicone after a few months of use.

but if you drive them very softly at 10-20% of max. current or even lower they add a good portion of reds 600-750nm into your grow spectrum.


this is what a white 1800K full spectrum 380-780nm 100W-chip can do with 1,7W ...
(6 x 100W chip in paralell with a 10W driver )

Purple light too? Because white light look a lot brighter to our eyes than purple light (even if it's the same photon count for the plants).

Been using the light for 6 months now and I was using two hids 600w. Well since I switched my plants have been bigger my yield have been bigger I can stick 10 instead of 8 under the cirrus 1k. This is a very good light and very good value for money I let results do the talking for me here my instagram grandmaster_tryhard

CobKits said:

i personally wouldnt take an inefficient light for free... electricity is too expensive. At $1000 for unknown efficiency its not really in the conversation

i would be interested in actual measurements if you do any (like measuring actual power draw at the wall, and measuring actual temperature increase in a sealed room vs an HID of known wattage). I'd be leery to trust any 'spec' they provide base on rest of the site



thats not the real question, any light starting at a $19 shop light can grow great product



for 1000W and $1000 it should be greatly exceeding the production of a 1000W HID or its a loss. matching yield of 1000W HID at 3-4X the price is no bargain. Glad you got a deal on it but again people need to evaluate it on what it would cost them

Click to expand...

Hi I’m using the light and my yield are bigger my plants are bigger I have replaced two hps 600w lights and it out performs them my electric cost a day was 8 to 9gbp a day it now 4gbp a day. Heat wise there a heat wave in the uk at moment and my tents not exceeded 28c if I was on my hids probley with my intake pulling warm air in be at 35c easily. The issues I had last summer I have not had this summer. The plants in the picture from seed 28 days then flipped

Rahz said:

Even if their 1000w can replace 1000w HPS there's no electrical savings and it costs more. I don't see any good points there.

This is my thoughts... Two of my lights grow as well as a 1k HPS Nanolux DE at 280watts each (that can be run higher). I get hands down a better spread of light, HPS is a joke in comparison... Even when comparing watts my home made LED destroy a 1k HPS.

I say all this because I see a light that is probably running cobs "very hard," destroying their efficiency. On top of that the footprint would cause a pretty condensed hotspot. Their claims of being the best growing LED light is simply un-provable so the claim can be made without challenge. I see a gimmick, a lie, a mid range LED light that uses 2x the energy my lights use. There is simply no way a small light like the one in the OP shows covering a 4x4 without decent ceiling height.

I talked about this a lot with people in real life, not internet life. Quantum boards style light on a PCB simply have so many advantages that cob lights will go away unless some magical advancement occurs that can't be applied to diodes on a PCB. I will be building new lights soon, 190lm/w PCB build thats 12 inches wide and 42 inches long. At 250watts they will cover a 2x4 areas SUPER soild, but cover a 3x5 area pretty decent... I base this on my current LM561C build that's two 54 strips less of diodes, 108 diodes less. These lights are literally half an inch think as I run the driver hung on a wall, not sitting on the heatsink of the light. Heat will be far less with my lights VS the lights in the OP, longevity of the light will be better, ppfd will be waaaay better, energy use will literally be half and ceiling height will be easily compatible in literally any grow space... The lights in the OP have ALL the restrictions of a HPS light, it makes no sense, it's literally going backwards for LED.

Will their light grow? Sure... But with not a single positive of going with LED lights over HPS. I think it's pure chit, not to mention I didn't see what cobs they even use.

You seem to be fighting out the gate in anticipation on people fighting you...

The light will grow, and probably grow well. As far as the watt draw, the horrible color to work under, the tight hotspot, the heat it will produce and undoubtedly having to raise the light high as or higher than a HPS means the light has no value over HPS.

People push timber, HLG, cobkits and so on because they are all so far ahead of the "big companies" out there. If KIND led came out with a decent light that used high end diodes or cobs while not over driving them then people would say "get this KIND LED..." Of course KIND led costs 3-4 times as much as it costs for me to build a light that's superior soooo I'd have a hard time recommending that brand to anyone.

If you like the light great, but if you did a side by side with a free HLG and a free whatever that light is where wattage draw had to be matched you would probably grow near 2x as much under HLG than whatever that light is. So that's why people recommend good lights over bad lights, it's almost immoral to recommend a crap light like the one in the OP. If anyone here did recommend that light they would lose credibility on these forums because it's a horrible light, that will grow... without a single benefit of an LED.
