New Fluval Plant LED- no par data available


Am considering buying two of the new 24" Fluval Led Aqualife and Plant lights. They look great and have the right color spectrums for plants. However, no PAR data is available for these lights. Only lumens values. The one I'm looking at have 1495.

Called Fluval and they do not see the need to provide PAR values. I have a 24" deep 56 gallon column tank, with 3-4" substrate. Would thse provide medium at best light or low end high? Fluval does specifically note that their new lower end Ultra Bright LEDs will support plants that require low light.

In a few months, I could answer your question from experience, as I just ordered one of those for a 20 gallon high. Since they're new, I couldn't find much info, but I saw one on a display tank at a LFS, and liked the looks of it enough to take a chance.

This article might be helpful. It suggests .6 Watts per gallon with good quality LEDs, and with two of those Fluvals on a 56, you'd have almost 1 Watt per gallon:

They've been out a week or two. It's between this and a Marineland Aquatic Plant light. I need more data on the Fluval to pull the trigger.

It would be nice to see a spectral graph on the new Fluval. But I'm at least glad to see it has dedicated LEDs in the 460 and 640nm wavelengths. I also couldn't find a spectral graph for the Marineland Plant model.

How much was the 24inch plant version, can't find a price right now. The black fixture isn't very pleasing to the eyes.

The 24" Fluval LED Plant light can be bought on Petco's site for $169 and on Dr. Foster and Smith's for $194. I think they look nice. I've heard they are very well constructed too.

Simply need PAR data for the Fluvals. For example, the Marineland Aquatic Plant light (24") has a listed PAR value of 83 at a 24" depth. Ideally, I would be able to grow plants with high light requirements (low end of). I'm left guessing about the new Fluvals. Calling their 1-800 number wasn't usefu,l as they don't believe in providing PAR values, despite just about every other manufacturer providing this.

Just checked Petco's website and the new Fluval 24" Full Spectrum Plant Light dropped in price from $169 yesterday to $127.49 on sale today.

I don't know about the plant one but I know the double bright one will grow higher light plants. I have an 18" over a ten gallon and its been working great for 2 months or so. The plants have had great growth.

I found some detailed info at http://www.drsfostersmith.com/produc...3554&subref=AA

From the specs which I've copied. Look a bit redundant to me. It's pointless use a 15000 and a 6000K led together. There's no benefit to plants for a 15000K led for it's too far into the blue. It looks like this. https://www.google.com/search?client...ml%3B360%3B257
The 6000K is good though. As for the other leds there should be a broader range to cover adequately plant needs and for aesthetic preferences.

Spectrums of different K temp leds.
http://www.google.com/imgres?imgurl=...9QEwAw&dur=468
The info is out there as you will can see but a bit of searching is required on your part to find it.

You can grow those chosen plants you want in high light too, but so suppose you want to in the future grow plants that like higher light. This light may not have that latitude.

Consider too www.buildmyled.com [BML] the diy app. before you buy. Input these leds into the diy app. Also look through this thread to see what a prefab led light will look like from BML. http://www.plantedtank.net/forums/sh...d.php?t=198196
A CRI of 98. Giving a noontime K temp 5500-5900...
Input other color leds and watch how the numbers change.
  • 5700K
  • 5000K
  • 6500K
  • 470nm Blue
  • 505nm Cyan
  • 505nm Cyan

^ So are you saying the 24inch version can't grow carpeting plants?
