I looked around for more info on these too.

I think they were quite a bit closer to the single version... not much to hope for if you're growing plants.

In other news, I'll be deploying Finnex Ray 2 units over my 46g bow & 20T right after Christmas!

Is it possible to get PAR data on stock Fluval LED fixtures?

More specifically, I'm looking for PAR data on the Fluval Spec V LED fixture.

May be a shot in the dark...but a shot nonetheless lol.

Thanks!

Hi samamorgan,

Here is some information on the 20 watt AH Supply LED lamp; it is also available in 15 watt and 26 watt configurations.

The L.E.D. lamp arrays run on standard 110/120 VAC and do not require a driver/ballast. After I plugged the L.E.D. array into the 2G11 socket and inserted the LED lamp array into the holders/stand-offs it was ready to go!

I decided to run it through its paces and it performed excellently. The L.E.D.s all lit simultaneously and with equal brightness. I put it on my 20 gallon tank and it looked identical in spectrum to the 6700K PC bulb I was using which would make sense since the LED lamp is rated 6400K. GSAS has a PAR meter for our members so I immediately called and reserved the next open slot so I could run some PAR tests; here are the results:


Please note that the PAR readings shown were taken in ‘open air’ and would likely be higher due to internal reflection if I had taken them in an aquarium filled with water. I will try to take readings in one of my aquariums in the future. How do these PAR readings compare to a AH Supply Power Compact kit for example? I have a 2X36 watt AH Supply PC kit (72 watts total) on my 30 gallon. At the substrate level (13”) the PAR for that fixture is about 95 so these 20 watt LED lamp arrays put out about 80% of the light intensity of my PC's while only consuming about 28% of the wattage.

AH Supply offers the LED lamp arrays in three sizes. There is a 15 watt that is 17” long which would be great for a 10 gallon or two end to end they cover the length of a 36” long tank. There are two LED lamp offerings that are 22” long; the 20 watt which I have just tested and a more powerful 26 watt unit.

Thanks for the information about AH supply's leds!

Could you provide a link for those of us who have looked but can find only their PC stuff??

Thanks!

There, you have to click on "easy ordering" link to see "leds" menu.

Hi Squawkbert;

Here is a link to the area of the website with the ordering information.

Here is a link to the thread I started on covering my experience and the test results of the AHS LED lamp arrays.

[Squawkbert]

I have my 18" and 36" Ray-2 fixtures installed.

I absolutely love the 18" unit. It is perfect for my 20T and looks great.

The 36" one was DOA (it is basically a pair of the 18" boards in a 36" housing - only one half would light up). The vendor (AquaVibrant) worked with me on getting me a replacement in time for Christmas and they even refunded my postage for returning the dead unit to them, so they get high marks for customer service.

The 36" unit also works well, but is not a significant improvement (visually - plants have yet to state a preference) over the 96W PC it replaced. I guess I was expecting it to be a little brighter than the 96W, but as long as plants grow, I will be happy saving $ on my electric bill & lightbulbs.

While searching for a good light for the high tech 10 gallon ADA Tank I'm planning for this summer, I cam across this post. I wanted to visualize the data in the post, so I threw the data points into Excel and whipped up a quick graph. The graph gradient is outlined in the original post: low light, medium light, high light. It doesn't contain all the lights listed in the post as a lot of them are designed for marine use and have PAR values so high it skewed the graph. I'm posting it in case anyone else finds it useful.



I'm also very curious to see PAR ratings for the Marineland Aquatic Plant Lighting System [marineland.com]. It's similar to the Marineland Reef Capable light but at a freshwater temperature. Has anyone seen data for this light?

Looks like TMC has another Grobeam that's not on this list.
TMC GroBeam 1500 Ultima Tile --65K
http://www.aquariumonline.co.uk/aqua...ile_P2999.html

Anyone know the PAR values on these?

[mixermandan]

I emailed Aqueon for some information on this light and got a par chart for all the sizes with tank sizes, distances measured, average par values, max par values, number of bulbs, etc... would anyone be interested in that? I recently aquired one of these lights and have been experimenting with it on my tank since it is an aqueon tank it fit perfectly unlike some of the other LED arrays.

I would be very interested in the chart.

Recieved this table from Aqueon about their fixtures.

If only I can bring the company par meter home I can do some real par test reading.
I'll have to ask and hope for the best ^^

Hi,

Maxspect has put out a repartition grid for PAR on their R420r model, they have the A8000 (8000k) for planted tank... don't know if it's valuable information for that sticky.

GREAT POST!!! tons of info here!!!!
