This is with an APOGEE and again, this is why we have not released any official data since 1) PAR should be higher than what is shown 2) The data collected in our office is in a very amateurish environment.

Holy crap Lowe never ever take a pic with a cheater tape! Give me your man card.

So basically it should be a bit higher than 45 since that meter doesn't measure the red light well? Anyone know of a par meter that will read red light?

You shouldn't take life to seriously. You'll never get out alive.

Sure, the LiCor PAR meter reads the whole PAR spectrum very well. But, do you really need accurate PAR measurements so badly that you would spend thousands of dollars to make them?

I purchased 3 of these lights for my 3 foot by 3 foot mostly crypt cube.
how deep is your cube?

Bingo! You already own it, fire it up and see what grows - after that the numbers don't matter

The first thing any manufacturer of a light aimed at planted or marine coral tanks should do is measure PAR at different depths on all the different lengths of lights they are going to offer. Finnex has done a better job of this than most and I hope they make it a priority on this light. I would think a manufacturer could make their money back plus more by offering this information. Couldn't they rent a meter or borrow one? I am sure there are plenty of people waiting on this information before they pull the trigger and buy one. I want one of these for Christmas if they can do it. Otherwise I don't. I would bet the Apogee reading is closer to being right than you think and I personally hope for 30-35 umol/s from a 48" light at 24" depth. Not all of us are looking for huge amounts of light.

Well, a regular Fugeray 48" gives 34 PAR at 24" dead center according to the charts:


And the Ray2 48" gives 50 PAR at 24" (on center)


The Planted+ has to be in between there somewhere, probably closer to the Fugeray. As someone who took off a Fugeray and put on a same-length Planted + I can tell you the color is great (but not heavy handed like a monster ray) and it appears noticeable a step brighter. Not crazy Ray2 or Reef bright, just brighter.

You you all think the Fugeray planted + would work ok with emersed riparium plants?

Sure, same as it would in an aquarium - growing power falls off with height.

I have the 48" Marineland Aquatic Freshwater LED fixture on my 120-gallon 24" deep tank.
I have goldfish so not heavily planted, but have anubias, temple plants, java fern, crypts, amazon sword and onion plants.
I recently purchased the Finnex Planted+ 48" fixture but debating if that is sufficient PAR along with the Msrineland. Would the FugeRay2 be better?
I would like to be in the middle of the medium-light category just to have options.
I dose Excel and Florish. Also use root tabs.
What should I do??
