So having returned to the hobby recently, for my next project, I’m planning a 60 x 60 x 60 tank, I require a light that can successfully grow a decent carpet at that depth - any ideas.

Depends on your budget and aesthetic wishes, of course, Kessil light likely will do... If on a budget some descent COB LED floodlights could be adequate as well.

Kessil also uses a strong COB, these LEDs perform best nowadays regarding surface area vs intensity and consumption...

Take a look at this also a very tall tank and using floodlights...

There are pretty strong relatively affordable and easy to install DIY COB LED units out there but they absolutely require descent cooling heatsinks and or fans. Depending on your budget and DIY skills there are quite enough options.

But IMHO the easiest and cheapest would be a decent floodlight. :) The best option would be a dimmable version.

whats your budget?

best light bang for buck - Twinstar S (60cm depth it might be slow with say a hair grass carpet though).

Best light next one up (another league from Twinstar S) - ADA Aquasky RGB

Best light hands down - ADA Solar RGB

well that’s the issue, I don’t really fancy spending nearly 4 hundred for the kessil unit unless I really have to and that doesn’t even include the controller, esp if they’re equivalents out there. I do like the idea of floods, but penertaton, spectrum and aesthetics are relevant factors. I also like the Fluval 3.0‘s im using now, but Im looking to be more hands on with this tank and bars get in the way. I’m checking out now the dimmable floods and the ADA

With 60cm depth you are going to need a light with a decent punch to get enough light at the substrate. Most lights are great up to about 30-40cm depth.

As mentioned above, kessils are good for deep tanks, or for a budget alternative you could look at these.

1 or 2 of these might be an option, according to the reviews not bad and easily dimmable. Not explained with what but I assume he used a phase dimmer... A Variac would work better I guess.

50 watts and +/- 4000 lumen

But as said above you need some punch, and lights with a punch get hot... And one thing LEDs don't like is heat, it will shorten its lifespan.

You could go for a DIY options like this.

I made a few lights in the past with this kind of COBs the intensity of these lights is unreal. But it runs very hot and realy needs a massive heatsink and there are the minus points massive heatsinks are expensive. But it works with smaller ones too and then it needs a fan cooling. Regarding electronics they are relatively easy to install directly hooked to the main VAC 220 and most can be dimmed with a VARIAC. (Variable AC voltage regulator) The you need some DIY skills fixing it all in a hood. :)
