    never heard of that light mate. I have a Mars 600 and several 300s. I can definitely say you cant go wrong with them.

    @yazad they look that pink/purple due to the mixture of red and blue led's that most of the commercially available units come with.
    The red and blue led's target specific wavelengths known to stimulate photosythesis and target chlorophyll. An alien looking dark pink lights spectrum would look something like this - notice the targeted spikes at specific wavelengths.

    The 6500k led you have is perfectly good and probably uses a cob led, some of the new grow lights are now using these instead of the mixed spectrum small diodes above. You can see below the wavelengths produced by a 5000k in the chart below, rather than specific bandwidths being targeted it is covering lots of bandwidths in the visible spectrum.

    The 6500k is a cool white spectrum with more blue and less red, this can be seem in the charts below, it is low in the 610-720nm wavelengths and higher/weighted towards 400-520nm range.

    For an auto I think perhaps 2700k (warm white) would be better but I'm sure you can produce excellent buds with either :)
    I grew for a few years with PLL T5s with 4000k tubes and they produced superb flowers :)

    Using what you have is fine for now but when you upgrade either go for a 2700k or 4000k light similar to the one you have or get an led grow light (pink) which ever is more affordable ;)

    It wouldn't hurt to buy the 4500k, but it would be better if you could get 2700k, then you could use both the 2700k and the 6500k together for mixed spectrum or as you suggested, one for veg and one for flower :)
