Decent led lighting options for a 15in cube

I am trying to find a decent light for my 55L cube (Aquaone Nano40, 15in/40cm cubed).

It's currently got the standard 14w led light over it, but it just doesn't have the power or coverage I want for my setup (medium-high density planting, EI, CO2).

I've spent a lot of time thinking about DIY, but despite having built LED/cob grow lights previously and having the know how to make a controller, I am too indecisive and time poor to do my own build. I've found the part selection just too overwhelming at the moment. The idea isn't completely off the cards, however.

Regarding pre-built lights, the biggest issue I have is I can't really find anything that suits my dimensional constraints.

The Chihiros WRGB 30 seems to be the best contender. It has 6500k + RGB which covers my desire to control colour spectrum, but the lack of ability to smoothly step between light intensities is a major-major turn off. Is their any way around this? I've churned through google but haven't turned up anything conclusive.

Can anyone recommend anything? Or should I take a concrete pill and start a thread in the DIY forum...

Bigger problem is you are in New Zealand..
No idea what you can get nor pricing..

That said about the easiest build is for your style tank..

30W COB , heatsink..

Sadly, ATM the only real commercial unit is an
AI Prime freshwater..

I just transitioned to the Aqua Worx Orion 12" LED light on my UNS 40C, which is a 16" cube and so far I think that it has the power I wanted for similar light levels. It outputs 24W and allegedly has 90 PAR at 16" depth.

Hey AcidGambit how are you getting along with the Aqua Worx Orion 12" LED? I have the same light over the same tank. However, I don't think I trust the PAR data that the manufacturer publishes for this light as I have not been able to grow plants that demand medium light levels (all other tank parameters optimal).

I am thinking of purchasing a Twinstar 300EA, but not sure this would actually be any better of a light. Can't seem to find lumen data for the Aqua Worx and since I don't trust the PAR data I don't want to use that as a point of comparison.

Thoughts?

I wish that I could be more helpful. Unfortunately, however, I've recently determined (with the help of forum members) that my whole-home water softener has been poisoning my efforts. I'm in the process of re-doing my tank and building a RODI/water-mixing station. With that said, I think that the light has some decent power. My problem was that the salt from the water softener appears to have been killing the older growth on my plants. But the new growth always looked decent and had low inter-node distance, which is indicative of good lighting.

I ended up going with the chihiros wrgb. It's definitely more than enough light, however my faster growing stem plants at the rear of the tank do reach forward toward the light which is over the center of the tank
