Hello all I'm seeking any feedback or experience with LED lights on a planted aquarium. I see different colored lights, mainly whites, white and blues for reef tanks and RGB for planted tanks. As far as spectrum, colors and lumens etc. its a bit confusing as to which would be best and cheapest for a planted tank. Obviosly the planted led kit sounds the best, but a bit expensive and I don't know how necessary all the colors are. Appreciate any feedback Im looking to replace my super cheap factory lights for my 55gal 48" L tank.

so far I work with LEDs only on my small tanks (30 l max). Those are run of the mill GU10 LED bulbs of varying wattage and between 6000 and 6500 K.
I should think a good "value for money" solution for larger tanks could be 'T8 Led tubes'. As the name indicates, they fit the normal T8 fitting and come in standard length (60, 90, 120 and 150 cm) and, depending on manufacturer, different light colors (3000 to 6500 K). I assume that your "super cheap factory lights" are T8s so you won't have to mod the entire hood to fit LEDs. You'd have to search for a supplier somewhere in the states and see what you can get. Just to give you an idea: I recently had a look at a 120 cm tube, 20 watts, 4000 K, 1800 lm, which would have cost me around € 32,-
As I have good plant growth with ordinary 4000 K T5s I don' see why LEDs should be any deifferent. And of course, should you want more of a "day light color", you could go for the 6500 K.
The RGB LED strips you mention are in my opinion good for light effects (for those who fancy some disco or a pink tank ) or a night (moon) light.
I hope this helps to get you started.
