Hmm perhaps they have done away with the colortone then..
That bulb looks good 6500k is on the blueish side of the spectrum but is just fine for plant growth.
One thing to remember as a bulb deviates from the 5000k sunlight point. CRI will go down (which is why it doesn't always apply to growing plants) Also lumen output rating will drop a little.
Would be worth checking against their ultralume line also. They come in 5000-6500k models but should put out more lumens. Whether the increase in price is worth it or not would be something you would have to decide.
