finnally found your light spec:
View attachment 2272718
seem it's 400W old tech LED 51cmx28cm wich could be good enough for a 2x3 2x4 or eventually even a 3x3.
but even better if you want to get a full kit with some of the latest LED.
here a few of the most used and rather cheap LED brand.
spiderfarmer, hlg, ac infinity, vivosun, phlizon, lumatek, viparspectra, mars hydro
check their officals web site and compare, most of them have continentals warehouses, and officials websites ( .com, .uk, .eu, .au ,etc.)
For a tent size you usually find a range of 2-3 models per brand that will fit and scale.
Models with larger dimension and more Watt usually offer a more even light coverage and dispersion near tent borders but you may not use them 100% close to the plants.
Each brand will have their tweak regarding the spectrum, led layout, app, fan, orientability and whatever but truth is when it come to comparing the end results with panel equivalent in power amongst thoose brands you won't see much difference with the final results.
(i would avoid mars hydro TS series it's not uncommon some people had some issues with them, also i think most viparspectra new models are not fully dimmable but with step)
(i m with spiderfarmer, i like the simplicity of their fixtures and they had the best panel dimension for my 2x3 tents)
