You might want a look at these cob units.

https://www.banggood.com/150W-15000...l?rmmds=myorder&ID=383748036&cur_warehouse=CN

they outperform a 1000 watts metal halide with ease less than 1/6 the power consumption. It hooks straight to mains AC220 and can be dimmed with VARIAC of necessary.

The challenge is to build sufficient housing for it, it needs a heatsink and preferably forced fan cooling to prolong its lifespan.

I did rebuild a regular R7S 1000W floodlight housing with such a unit for in the garden. And it performs really impressive.

Anyway, if you don't mind ditching the RGB en controllable spectrum idea and go with a 6500K, this might save you some time and money. :thumbup:

Hi , yes I saw them already. They are pretty powerful, just like u said they need good cooling system.

The newest generation HD Prime freshwater include 80* lens as standard and has a proper Moonlight channel now (that isn’t BLUE)
(previously AI has offered various lens kits BUT this no longer appears on their Accessories page)

https://www.aquaillumination.com/products/prime-freshwater

(unfortunately, AI hasn’t updated their “light sciences data” to allow comparisons of their new generation lights vs previous generations)

And Jake Adams review (of course)
https://reefbuilders.com/2019/10/04...me-in-four-versions-reef-sol-fuge-freshwater/

As Marcel mentions, DIY builds can be a sound solution - there are a few LED builds on ukaps (including updated versions)

AquaOwner always has interesting lighting reviews and videos

ADA approach uses rich soil to supplement low N and P in the water column. It won’t work with hungry plants
Does this mean you find the Green Aqua Gallery only includes “easy” plants?
(or growth is poor?)
:confused:

And I guess FOA would also fall into that category

Hi @Nikola

To give some experience on the AI primes, I will share my data!

I have a 60cm deep tank and 90 cm long. I have 2x AI primes. The most light-hungry plant that I have is pogostemon erectus (but I do have a carpet of S. repens). I will be adding more hungry plants so I will have a better comparison for that for you; however, until then :

The plants grow (and I am certain I could reduce the light to maintain growth). I run the following:
Warm white: 39%
Cool white: 39%
Deep red: 35%
Blue: 10%
Green: 20%

Now, I do have some overlap of light due to my length (the primes cover 24 inch each iirc - it might be 28). They are also 1 foot above the water.

So, with all that in mind, I think these could probably grow stuff at 80cm ... maybe 1m?

According to to Dennis Wong, the ADA gallery in Niigata, Japan is dominated by easy plants.

ADA tanks generally also choose easy growing plants that grow well in a large range of conditions; many of their tanks feature java fern and anubias, cryptocoryne species. The usage of easy plants coupled with good design results in tanks that are aesthetically pleasing yet easy to maintain.

I don’t know much about Green Aqua Gallery, but can attest that the Sumida Aquarium I visited in Tokyo where Amano built his last big nature aquariums are dominated by easy plants exclusively.

If I had a deep tank, I would use a combination of narrow and wide beam LEDs. The narrow beam would shine at the substrate to grow carpet plants and the wide beam to cover the top where narrow beam miss. Unless your choice is all high light Dutch , choice of plants can be tailored to the light distribution which does not have to homogeneous; for instance, placing high light plants on top or near high PAR zone, and low light plants in shady or low PAR zone.

Thanks people, u gave me a lot off info here. AI primes as I can see are really good choice. I already have some ideas in my head. And like @tiger15 said, the best is to target some areas in aquarium for highlight plants, and less demanding plants to put in less lighted areas.

Hope that soon I will buy a house first, than aquarium is going (house will chose by place for aquarium, but don't tell it to my wife :))

that beautiful space for an aquarium will be just as lovely for a fancy shelf unit for all your photos and nik naks collected over the years! ;)
