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

"The Cirrus 1K utilizes full-spectrum driverless COBs"
that part concerns me. Obv not full spectrum, they should be using white cobs as well (at least)
$1/watt is a good price point though. Just not for blurple. And does driverless mean they are using those cheap AC COBs? Seems suspect. I also noted its a 220+v input, so no good in Americas.

Seems like a great deal. How are they not full spectrum?
Thats the spectrum from ledgrowlightsdepot
Looks like its hitting the 660 range better than most cobs. Seems like its still hitting some greens and yellows, just not much. But I'm no expert. School me.

They aren't full spectrum because of the graph you just posted, it is missing a huge chunk of the mccree curve, those blurple lights suck. I wouldn't bother with this spectrum , feels like it's still in the 2008 period of targeting certain wavelengths.Seems like a great deal. How are they not full spectrum?

This. I saw that and the strangely familiar pinkish hue... also, seems like their bread and butter is giant LED billboards, not horticulture.

Could you elaborate on this? I have seen and have personally grown really great crops with "blurple" lights. I understand that white lights work really well, but even those have a certain amount of spectral targeting with the different kelvin temperatures. Are you trying to say that there is no value to higher amounts of red and blue? And that 660, 440-450 peaks make no difference?

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.

It's just another cool-looking light priced too high and will likely not be around for very long. I have TRIED to talk the Flip Chip guys into considering DRASTICALLY lowering their pricing in order to get people to take a bite....but they have other ideas. The company name changes, a new spokesman appears and pretends to be interested in feedback....I give them my feedback....no response....company name changes and a new light appears....repeat.
It's too bad, because I wanted to see what they could do with the Flip Chip COBs. They (apparently) have a HUGE manufacturing facility and can pretty much make anything they want -all in-house! You would think that would be an advantage to the cost/pricing. But they still make expensive, blurple lights with big fish-eye lenses!
The disadvantages to using blurples is that they suck to work around because it's hard for humans to see in that spectrum! Plants will grow under blurple, yes....but some pathogens flourish in the absence of certain other colors which make up "white" light, too. I don't think there is any significant advantage to using blurples as opposed to a more normal warm white spectrum. I've seen all kinds of grows on this website -some used blurple and got great results, some used white and got great results...But far and away, white light is more comfortable to work in and the advantage of you spending more time around your plants and tending to them and seeing them better is probably a bigger advantage to the overall well-being of the plants.

I have been working with them and their heat sinks and have played with their white COBs and was happy until I got the Citizens. I do like the heat sink that they use on their grow lights. The are a heat pipe design, but yes working under blurple SUCKS. Everyone else at flip chip is still there. Only Alex left.

Im not entirely sure what a flip-chip is, but supposedly this CIrrus 1K uses Flip Chip COBs.
Wouldn't it be the same as any other LED. No swapping bulbs, better heat management, better spectrum, and I would guess with an equal wattage LED you will still be more efficient, so more light and bigger footprint, which would mean fewer fixtures and in turn less electricity. Just playing devils advocate, I'd definitely like to see someone grow with this thing.
EDIT: Does anyone know anything about the "heat exchangers" they use for this? What the heck is that?

I don't know how long their emitters are rated to last.
It's 1000 watts either way so the electricity required to maintain a specific temp should be similar.
I'm not sure that's the case. Red/blue is generally absent any radiation in the 680-700nm range. That could be an issue, but either way blurple hasn't really been tested against white on a flux -vs- flux basis as far as I know.
Edit: looking at their SPD it looks like it does include some power in the 680-700 range. Still doesn't mean it's a better spectrum but I like it better than the 450/630 combo.
I don't know enough about it to provide a direct comparison, which would be a problem for me. If I wanted to be a red/blue guinea pig I would really want to have some absolute data available. Maybe contact the company and see what information they can provide.

Sweet! Where did you get one at that price? I would be all over that
Be all over quantum boards from HLG...….
