This is a nice light...I tested the new spectrum at AE and look forward to testing the final version soon. A few points regarding the review from Aquarium Coop though:
The PAR values Fluval released for the 48" 2.0 model at that depth are 45-50 umol/m2/s, and this new spectrum should be similar. Why are the values so different in the linked review? First, that sensor he's using is terrible, it's not much better than using a lux meter app on your phone, so the measurements are way off. Second, the new spectrum is a bit warmer due to a greater amount of red, and that sensor completely cuts off spectral measurements at the far ends of the visible light range, so the values reported for both the 2.0 and 3.0 are incorrect with the 3.0 likely being more erroneously "measured" than the 2.0. Both versions should be similar output, perhaps even a bit higher for the 3.0. But we'll need to wait for Fluval or someone with a decent quantum meter to post PAR measurements.
In the meantime, I look forward to your feedback! I think the features and app control make this a very hard price to beat for most planted tank setups.
