Has anyone seen the new Fluval planted tank LEDs?
They look nice in pics but haven't arrived locally yet.

Are all these PAR readings @ 12" ? Am having a hard time with how this is written up.

That's what it looks like. With Average and Max though it does seem to add to the confusion a little bit. All of that at 12"? My low light plants seem to be doing alright so far.

My Anubias Fraz on a piece of driftwood, so probably 12 inches away if I had to guess has added a few leaves in 2 weeks. It is 6 almost 7 when I got it it was 4.

My italian vals are shooting runners, but not noticeablly growing taller.

Hornwort it shooting a branch upward towards the light.

Red Wendetti and Giant Hygro are slower, but seem to be recovering from T8. (they are at 18 inches deep or so).

Moneywort is holding steady.

Riccia and Flame moss are status quo.

Trying to figure it all out because I run TWO units. 4 Day Wites and 2 Colormax bulbs on my 36" long tank that's almost 24" to the bottom of the substrate.

Does running two units (6 bulbs) basically double PAR ?

I have AQ Modular LED 20'' with 2 daylight and 1 colormax. Would it increase or decrease the data of PAR below?

I think it would slightly decrease as the ColorMax doesn't have as many "white" bulbs. Could be wrong though.

Still waiting to see if anyone knows if running 2 units doubles the PAR rating as well.

Running two lights with them sitting side by side, not separated by more than an inch or so, will double the PAR. This is true for any type of lighting, unless the light has optics that give very narrow beams of light.

So, as I think, ColorMax has no advantage. Am I correct?

Powerful!

Default Colormax bulbs

First, sorry for the way that chart came out it was that way from Aqueon and I don't have the time to edit it for the forum
Second, looking at the color spectrum for the colormax bulbs for this fixture all they do is replace a couple of the white LEDs with red ones, so if you read the chart it will give you the PAR value for 1, 2, and 3 bulbs which should be pretty similar but what you do get is a shift of spectrum from blue to red slightly because of a peak in red light from the red LED's (the spectrum is on the side of the bulb package just compare them)...

so given that the plants absorb blue light (the daywhite bulbs have just a blue spike) better you would most likely get better growth from the day white bulbs, the red emitters will still help and not all together detract from your par too much I would think but are really only good to adjust the visible color to a warmer hue?

I was running 2 colormax and 1 daywhite over my tank, I just switched to 2 day whites and 1 colormax, and I think my growth is slightly better with 2 day whites in place, and not much of a color difference. I'm also thinking that if I bust off the tabs that hold the bulbs and strap 4 bulbs together and add another power supply I can fit 4 side by side in the fixture increasing the output.... or maybe i'll just mod it some more (already did the moonlight) and replace the aqueon bulbs with high output LED strips. sorry... rambling

yes they are all measured at 12" at the top is a legend, i'd recomend copying and pasting the section you want into a chart or excell sheet its much easier to read that way

One company will build an 18 watt led fixture using six-three watt emitters, another company will use 36-half watt emitters. Are there advantages of one build over the other? Does one have better light penetration then the other? Will one produce more heat then the other? Would it be adventagous for a home builder to use more smaller emitters and use a wider range of light wave lengthes of light produced? Just askin.

Mixerman I spliced my light to add another led strip. I explain how in my moonlight mod thread.
