The wattage is right (you want 3 w leds), but that light has a toggle switch that YOU will need to flip to enjoy the white or actinics like marinelands I believe.
A timer will only turn one or the other on/off,you need to make the "transition"(everyday).
Look for reviews of anything you buy(I couldn't find one for that light on the link ).
The seller is reliable but the light is in question to me.
The actinics(blue) will make your fish color pop!!
Most planted people do 6500K (aprox) and the reefers do 10,000-20,000k.
is more "yellow" andthe higher K
are more "white blue"/"incredibly bright".
My currents are 12,000k on my 180 FW
I have actinic strips also, but many believe they are a source of "algae" in FW
and the spectrum is not as easily used...
They make colors POP!
It is really nice to have a day /night setting on a timer,but to do it you need separate power feeds for each light.
Look for a unit with 2 plugs.
If they are FW
safe these are the way to go!

I like my currents butthey are to much $$
Search "reefbar led
" on ebay and those are the same for way cheaper also.
I have never heard of ANYONE else besides me using or mentioning either of the two lights, soooo.....
