Which Cree?

[seaweed88]

I have made my mind up on what I want to build but now.....I see Cree has 3 different models. Can anyone make a suggestion on which one to get? I want to run 5watt neutral white and royal blue . I also need some of the 3 watt. Any help would be appreciated.
Thanks

The Cree XT-E offers an excellent value for a 5 watt LED. Are you sure you want to go with the neutral white? They are a bit on the yellow side. I attached a pic of my tank with two different Bins of Cool White. The regular is about 5.5K close to the neutral. If your looking for a more full spectrum the Cool White is full spectrum except for the Red. Adding a couple Warm Whites with the Cool White has been done with good results without the yellow of flat look of all Neutral. Also the Cool White has a larger 450nm spike which makes it better for photosynthesis.
