I have used
wrgb-2 - super bright; weak blue tooth module; never liked the spectrum no matter how i adjust it - visually with eyes it is not bad; but all my photos are too blue.
plant-3 - love the ip67; pretty bright if not injecting co2 - great app and warrranty - while not awful it is really is a bit yellow visually
onf (warm model) - not bad - nice app - kind of limited in adjustments - very limited form factor- fix length with no extending legs - it does fit on 40B.
blade freshwater - i'll probably test par this weekend but on the surface i like it a lot better than the above mentioned lights. It has some flaws such as not ip67 and sits on the tank unless you diy - seems very neutral visually and in pictures.
-
I'll be getting a couple of ghl 7006/7004 in a couple of months and hope they work well. They are kind of pricey so i'm not sure if they will offer much over the blade other than ip67.
-
I've not tried the twinstar (I think the newest model allows configuration but you used to have to pay extra for those features and i found that scummy at their price point).
kessel - something as twinstar (again i think they have a new model that address that point)
I've not tried the new wrgb-2 pro - this probably would fix my balance complaint but i don't think it is cost effective with the new blade.
plant 3.0 really set the bar at ip67 and 3 year warranty - something all these expensive models lack.
-
I'll be honest i'm pretty happy with how the plants do with the plant 3.0 in my low-tech tanks but wish they would update it with more balance set of led - on hi-tech it kind of lack the punch that the stronger lights provide. Even my wrgb2 struggle on my 40 (of course finding a proper balance that won't zap some plants while providing needed light for other plants is in itself a challenge since i just randomly toss in different species

)
