I also contacted Fluval out of curiosity for the PAR data but the one time they responded they told me PAR was a minor concern for plant growth and did not record that data.

Fluval LED lamp came in the mail today. It seems well made, fairly hefty, with a good heat sink design. The box has spectral graph info for all the constituent types of LEDs, and it does have good peaks in the red and blue areas. So far nothing to tell me it was a bad choice, but it will be at least a few weeks before I get the tank up and running.

Now that's funny.

Do they not realize how many customers they lose when they say things like that?

No idea. They wanted me to look at the spectrum data and were more concerned about wattage and lumens.

Not sure why you would consider spending more money on this over a Finnex Fugeray, Ray 2 or Monster Ray fixture?

I sent them an email asking for PAR info and got this in response:

We thank you for taking the time to contact us.
We are in the process of generating PAR values which will be available soon. Please stay in touch with Customer Service in the interim, thanks for you patience, we expect to have our values available by the end of June 2013. In the meantime you can rest assured our spectrum and color temperature is ideal for most aquatic plants, one strip the length of your aquarium for slow to medium growth rate plants, two strips for plants that are fast growing and supplied with CO2 injection.
Thank you,
Lisa Emery

So it sounds like it is only good for low-light plants, unless you want to buy two units. By the time you buy two, you might as well get a Ray II or something similar.

anyone have anymore info on these? i've had one on my 20L (since around the time they came out) and my plants have been doing well...still looking for opinions from others as i am no expert on lighting. any one find any PAR data yet?

i'm growing mainly low light plants.

i tore my tank down about a month ago and replanted, rescaped, ect. Installed pressurized co2 as well...

was having great growth with pressurized and this light but things seem to have slowed down a bit...

It shows an over abundance of blue spectrum but very low red... Although they do cover the spectrum, the intensity in the kelvin for plants seem inadequate. I hope i am wrong on this as the fixture looks really well made and sturdy.

I've seen a lot worse.. At that price though (and using small diodes) I'd have hoped that they used 660nm red ...I guess the point is a bit arguable..

Roses are Red, Violets are Blue, as long as you have both, plants will grow too.

i just bought a 24 inch and have it over a 29 gallon tank. it previously had a coralife dual bright on a low light shrimp tank. i used only one bulb on the coralife. i only had it for 2 days so far, brighter than the coralife and whiter light than i expected. the unit design is nice for the price and slime line design is nice. also the light all goes into the tank. i don't get the ambient light bleeding above the tank. the top of the fixture gets hot. i think the enclosure is made of aluminum so the heat can be removed without fans. light heat from the actual light below. since my tank has mainly java ferns i don't see fast growth. in this tank that is not what i want anyway. i am think about getting another one for a tank of crypts.
