Got a Green Elements EVO 30", for a 56G tank (30" x 18" x 24"H). Trying to find out PAR at 24".
Base on the this documentation, PAR = 130 @ 17" with dual EVO 48".
Is it correct to calculate EVO 30" PAR at 24" as below?
130/2 * (17/24) ^ 2 = 65 * 0.501 = 32.5

Very cool trick, Solcielo! I tested the BW freshwater pink 162 x 0.2w 48" fixture against a red/blue hydroponic light using this method, both in complete darkness except for the LEDs themselves, one by one, and I can 100% confirm that the BW pink fixture uses RGB diodes.

I wasn't able to edit my last post:
Well, the trick seemed to work to me. I saw separate red, blue and green lights relecting off the Bluray, all close in a row for each diode when I tested the BW pink fixture.

I saw NO other lights emitted from the red/blue hydroponic LED except those two colors: red and blue.

I'm building a hanging canopy that will house my soon-to-order Beamworks evo quad 3W led light 48" long. Can someone that has this light please give me 2 measurements? I need the overall length of fixture (NOT including any switches, cord housings, etc). AND I need the distance from the end of light to beginning of the first row of led's.

Posing a quick question. Is there any difference between the body styles of the pent .5w between the older turtleback and the new Razor/ELF, aside from body? It appears to have the same (or close) to LED count. My intention is to use on a 40B, but just want to ensure I'd be in the med light range with a single fixture. I'd prefer not to hang the fixture - so I'm concerned the 3W would not be a viable option given the spread.

I have the 3 row version of the razor, and it's pretty low light from what I can tell (just for mosses and anubias). Just looking for a little advice from pent/3w owners.

There is a 5 row ELF..Certainly the form would fit a low hung light for a 40b.
currently can't find the 36" though..
I take that back... 291488153333
Rated 6000 lumens..
One would hope that as the LED tech gets better so would the diodes..but no real proof AFAICT.
The .5W SMD emitters are fairly mature tech..

What are your thoughts on that as a medium light option for a 40B? Is that going to provide enough spread without being hung? Having seen some videos on the pent-style it looks like it should be enough for a 16" deep tank.

spread where? "As is" it is a bit too narrow for full f/b coverage at the water line.. (rough guesstimate) but once a few inches down, no problem.


worse comes to worse you throw a cheap Razor or stingray as a supplemental light..
Stingray for color isn't bad idea anyways..

$100 to light a 40b is not unreasonable..really.

most cheaper options will be led floods or cf lights, most likely hung..

5 row ELF for a total of $40 is pretty good..

A bit higher light is RayII/Planted plus combo..

to be honest, an inch or so higher legs on a single fixture would work too..

i have the 36 inch 24 led x 3 watts plant evo on my 65 that is 20 inch front to back and hung approximately 14 inches from the water line and it gives me pretty good coverage. thanks to jeffkrol who recommended it to me. its looking pretty good so far. i say this because if i try to lower the light, you can really see the spread or beam of the light inside your tank so when i raise it up 14 inches i can tell the coverage in my tank.

Whew just read through this entire thread but still pretty confused so looking for some suggestions please. I'm setting up a 46 gallon bow front and I'm planning to dose fertilizer and pressurized co2. I would like to grow some kind of carpeting plants, maybe HC. From reading the thread, the pent .5watt fixture is out since it will probably have issues penetrating down to the 20 inch depth. What if I got 2 pent .5watt fixtures? Seems like that would not really help with penetrating light down to substrate level?
The recommended choice seems to be the quad 3w fixture and hanging it maybe 15 inches above water line to get good coverage front to back. However, I'm not too thrilled with the idea of suspending the light so high above the water line since the tank will be next to a couch and with the light shining down it might bother people sitting right next to the tank?
The last choice is the tri 1watt fixture they have. If I got 2 of these fixture and put them directly on top of the glass top would that give me good enough coverage front to back and side to side? How about depth? Will the light be bright enough to grow carpeting plants at roughly 18 inch depth?(20inch tall tank - 2 inch substrate).
I would greatly appreciate it if anyone could give some advice. TIA

my guess (IME) is that you will a second fixture if you dont want to suspend or raise the fixture.

How would this light work on a 125 gallon? Java fern, anubius and water wisteria

Hey guys, currently have a 10 gallon with just crypts and soon to be buces and moss. Using an 8.5 watt Sylvania bulb hanging in a small dome light. Want to upgrade my lighting as I have excel and dry ferts on the way. Don't want/need high light, just want something better and to help the plants along better. How would this work?

Razor EA50 LED Light 18" 6500K
LED Aquarium Lighting Freshwater Bright

Have been thinking about a Stingray but if this is comparable for less $ that is cool with me. My tank is open top if that is a concern. I have heard some stories about Stingrays going out with minor splashing. I am using sponge filters.

Thanks for the help!
