Light for a 4ft planted tank

Hi guys,

I'm after a light for my 4ft planted aquarium. I'm running C02 and want to do carpeting plants etc. Currently I have 3 2ft lights and a led spotlight on the tank until I get a new 4ft light. Because of my setup would my only option be something like the fluval 3.0 planted? I really don't want to spend that much on a light. While the features are cool, I don't need them as I'm happy to just run it off a timer.

Or would something like this https://finepebbleaquarium.com.au/product/dalua-bw-120/ or https://www.aquaholicsonline.com.au/...spectrum-contr be good enough for high light plants ?

I live in Australia so we don't get a lot of the lights here as you people in Europe or the USA can get

All will depend on depth to gravel surface as to how much power you’ll need for carpeting plants. Big difference between a 10” tall tank and a 18” tall one.

Just measured the tank, it's 18.5" from bottom to top excluding the substrate and 17" including substrate. The tank is also 16" wide. We have strange tank measurements in Australia

Bump: Is something like this better? https://makemyled.com/1-x-flora-sun-...-florasun-401/

You would need 2 "spots"
Better off w/ a panel type light..

I have a 4ft tank, running 5 x 30w led floods and 2 x 20w led tubes with co2 and EI fertilizer.

If it fits you pocket you can try it out.
