Depending LED brand you'll find 500W to 800W models that will fit in term of panel dimension and scale in term of power. (you'll even find some 1000W if you use some CO2)
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)
as exemple here the models from
spiderfarmer that will fit a 4x4, all others brands will have some equivalence.
