LED review please

HI, I have an AquaOne PlantGlo, 60cm. I have no idea how good it is or its specs. Can somebody help me? thanks in advance

almost any LED w/ 1W or better emitters.. Or "a 'lot" of .5W ones..

how much is the budget and how much control do you want?
65-75's are wide so how much shading at the surface will you tolerate?

The video was not to endorse any LED, so I did not provide PAR or PUR values. Keep in mind PAR values can be very mis-leading because a LED could have a smaller PAR number, but have more PUR. Making an overall fixture with less "PAR" having much more growing power.

It's recommended to take a look at each emitter used in a LED to see our the PAR values are coming about.

Someone cannot say, oh this plant takes "this much PAR" to grow, because PAR is subjective from LED fixture to fixture.

Trigger334 Hi everyone,

I recently made this Aquarium LED PAR/PUR video I was hoping I could get some feedback on. It goes into some aspect I believe are a little misunderstood.

Note how T5's and MH output more light in those needed wavelengths; hence why I wouldn't use LEDs alone but rather as a supplement to MH or T5
not really...
It is an option, and one reefers lean to but in no way holds w/ a proper choice of LED's.. just ask the hort. world, when factoring in cost of operation..
sure 350W MH beats out a 20W led setup by sheer brute force and wasted watts..

In tests for plant nurseries (Green House, Hydroponics) full spectrum LEDs such as the newer generation TMC GroBeam Aquarium Lights, 3-10w LED Grow Lights, or even the older generation LED Grow Lights have been proven to surpass even Metal Halide Lights in both growth and useful output.

The picture to the left is the plant growth results comparing the same Kelvin output LED and Metal Halide Lights as measured by a PAR Meter (please click to enlarge view).

LED Summary; The bottom line is when you compare an LED Aquarium light to the many popular CFLs and even T5s in terms of lumens per watt, focused lumens, PAR, PUR, lower wasted yellow/green light energy, low heat output, energy consumption, long life (25,000 to 50,000 hours vs. 8000 hours), the modern recent generations of LED Fixtures are generally the best available aquarium light.
This includes the patented emitter ultra premium high PUR per watt AquaRay AquaBeam or GroBeam LEDs as well as the still VERY capable Aqua Illuminations, EcoTech Radion, ZetLight (aka Maxspect), and few others.
Most premium LEDs are a better light even in long term cost since (as an example) a 12 Watt Aqua Ray GroBeam 6500K daylight (either #600 Strip or Mini #400 Tile) can easily replace a up to a 80 Watt power compact (also daylight) when you compare ALL aspects of lighting as presented in this article.

When compared to even older T8/T12 aquarium lights, a forth generation TMC AquaBeam & GroBeam High End LEDs require only 15% (or less) of the wattage for the required light energy of a planted or reef aquarium.
This is as little as .6 watt per gallon for high light planted aquariums and .8 watt per gallon for Reef for the TMC AquaRay and 1.25 -1.5 watt per gallon for the ZetLight, EcoTech & Aqua Illuminations, and 1.75 -2.25 for many other LEDs such as the Ocean Revive, Taotronics, etc. (Acroporas may require a higher wattage input per gallon)

Any flaws of LED aquarium lights are quickly disappearing and based on the energy savings for the premium high PUR LEDs with PWM technology as compared to MH.
In fact for Planted Freshwater the top LED Lights (with the highest PUR) have few limits in their applications.

According to the Finnex representative, the Finnex Ray2 is better than the Planted Plus for big tanks
If my tank is 20 inches deep, and then say I have 3-4 inches of substrate, would either the Planted+ or Ray2 be enough for high-light requiring carpet plants? They would be sitting at 17 inches below the rank rim at the lowest. According to OP a PAR above 80 is considered high. I guess its cutting it too close?

DayOlder Great resource. Thank you for your time and work.

Aganor Hi all, i bought a brand new TMC 1500 Ultima 6500k DayLight, does anyone have any home PAR readings? the only one i have is the one on the reviews, 148 PAR @ 16",
I would be thankful for some hobbyst review on it since im going to use it at 16" from soil.

treyLcham i was just about to buy two marineland dual led light fixtures. My tank dimensions are 36x18x18" and i will have about 2.5in of soil when i put it together. My question is that i think 1of the 36"-48" would do good for low to at most mid so i was thinking in this case that two of them would give me a high range? IS this what i should be doing or should i only be getting one fixture. Also i would like to add that they would be hanging about 1foot above the water. Hope someone can answer this question! It would really help in my decision making before i go out and blow through 500$

BarryG I cannot find the blog that described a DIY retrofit of the stock light on the Fluval Spec V with solderless Cree LEDs.Â[censored]

Does anyone recall this discussion or have a recommendation for how this is done on the Fluval SpecÂ[censored]V?

Your advice would be appreciated.Â[censored]


Sincerely,Â[censored]

Several species of stem plants are rotting at the base or have totally died. I could not keep Pogostomen Helferi alive but my HC is doing fine. Growth of all plants has slowed. I am not sure it the problem is the penetration of light to the bottom of the tank or the spectrum.
What is that, almost 22" tall? Of course that's not going to do well. It's only putting out a little over 20 PAR at that depth. It's a great light for shorter tanks, not so much at all for tall ones. Heck, I have 2 on mine, and it's only 12" from the substrate.
