Yeah the discount got it under 1k and I had bought a 5x5 gorilla tent so that’s what made me buy it.

You guys are great! The hours I’ve spent trying to figure this shit out, I could be an Electrician by now. I’ve learnt more in a few hours on this forum than weeks of googling, thanks heaps!
And any other opinions on best lights for 4x4 or 5x5? I’d love to hear from experience now I’ve found it!

The new mars hydro lights are ok. But if you have the money get the hlg. I did a diy build with the help of @dbrn32. Or I would have gone with an hlg light.

Neither… I prefer chilLed over hlgs 650r
Did a lot of research on LED’s over several months. Compared all the top brands and ended up with the chilled growcraft x6 600 watt.t”

I am running it in a 5x5 and it is awesome.

I can appreciate it (chilled x6) totally. But 4x4 is “standard” and 5x5 is max… we all know what that means…(4×4). Take a look at the spectrums as well… pretty big difference.

That’s the 600 watt, the 5x5 is 1000 watt which has good efficiency and significantly more PPF 2450 µmoles
In comparison to hlgs 650r 1770 PPF on its highest setting.
Both great lights, but it’s not apples to apples. Please link me to chilLeds spectrum map, thanks

I agree. It’s 1300… more expensive. Less efficient, not as full spectrum… and it’s dyi.

Even compare the umols at the same height.

This is not an accurate statement, but thanks for sharing the spectrum.

To the OP, I would pick HLG all day everyday over all of Mars lights - hope that helps

The chilled tech x6 1000 runs about same efficacy as 650r when power levels are the same. So hard to say the 650r is more efficient. That is just over half power from the x6 1000. Plus it could potentially provide more even canopy coverage. Imo it’s superior light to hlg-650r, justifying higher price.

I apologize if I had misunderstood the info here… but this is what i was going off of. @dbrn32. So that full system number is the correct number to compare right?

I do apologize for the umols statement. Fake news for sure.
Efficacy and spectrum?
Happy Growing!!

That’s correct, at 1000 watts. Dimmed to match power consumption of the 650r they are going to be extremely close. The x6 1000 would just have a lot of reserve power at that point.
Is not necessarily anything I feel you should apologize for, just sharing the full picture for everyone to have better understanding.
