Seems to be similar to the rest just uses 9k white cree's
Seem overpriced because of the patent; similarly to the radians (looks like 900 for 120 watts)
I agree that leds do change spectrum depending on if they are dimmed or not etc but the amount is not going to kill our coral per say; Look at all the t5 fixtures heavy in blue; thats seems to be the most important for healthy coral ... all other bs is just nick picking efficiency and color preference.
If you want the best get a book on led's; and DIY.
