Does anyone know how you can determine the temperature rating (kelvin) of lights? Going through google doesn't show me anything except describing what it is. I assume there is a meter of some kind but only find PAR.
Measure light temperature?

Light temp is a misleading measure because it only describes how we perceive it visually. Much more accurate is wavelength distribution, and it's much more useful, too, especially for plant growth.
But to answer your original question: it's probably easiest to check on the manufacturer's website...

There isn't a brand name on the LED unit or anything? Is this for a planted tank? Honestly if you don't know what the K is on an LED fixture or the brand than I would doubt that you'd be able to find out if its enough PAR for plant growing.
Maybe post a picture of the fixture, someone might recognize it?

They are 165w dimable Chinese reef LED'S with fans off of Ebay. Just white and blue. Looking at them on ebay if they give a temp rating they will show the whites to be adjustable from 5000-18000K. I don't think Kelvin can be adjusted via a dimmer so I call BS on that. I bought them from a local reefer that upgraded to Radion. I want to attempt to grow plants.

And I have no doubt there is sufficient PAR. They are blinding!

I have seen some red LED's. If I add that would it help, or would that need to have an equal or close PAR value? It looks like most of the lights include only one or two reds in a fixture of this size. Maybe add a couple of 3 watt ones?
You don't need many. When I switched from a blue white led to an RGB my plants took off growth wise and some took on different colors.
I would try it out as is then add on something later if you are not satisfied. That way you can tell if what you add on actually makes a difference or not.

Well a dimer adjusts PAR. How many whites and how many blues are on this? Reef lighting tends to cause algae in planted tanks since the blues are not that great for plant growth and encourage more algae.
