How much LED?

I have a JBJ 3 gallon pico reef tank. It came with a stock 9w lamp that I want to upgrade to LED. I found this light on a chinese website that I use often to buy things. It is 2 W. You can look at the other specifics too (link at bottom). Would you be able to tell me if this is enough lighting for zoas and xenias and the basic stuff? What would you consider the power of this lighting? I am going to use the 9W on my hob refugium, so could the led be the only thing I would use on the tank. If I have to use the 9W too I would buy a different light for my refugium.

JAB Touch Sensor Switch Clip-on 2W 28-LED White + Blue Light Flexible Neck Lamp for Aquarium

Id imagine it would be a substantial downgrade. Those leds are ~.08 watts if im reading correctly. Might as well just put up xmas lights haha
