I don't think much information is available for LEDs and aquarium plants. I think wattage will not apply to LEDs since wattage measures the energy use and not necessarily the light output. Watts are becoming irrelevant; a 40 watt t5ho will produce much more light than a 40 watt t12, and it's even more extreme for LEDs. Most people I've seen have just bought plants and tested whether or not they'd live with the LEDs. That light appears a little "purple" so I feel like it is probably a bad spectrum for plants.
Also, CO2 and micronutrients are important but you need some source of nitrogen. That's usually fish or commercial fertilizers or something like potassium nitrate.
