LED Lighting Compendium

samamorgan · 06-20-2012, 07:37 AM

Oh and a little tidbit for reference. I had mild success growing low light plants under completely blue actinic LEDs designed for corals. This leads me to believe that actinic light would work just fine for plants if it met the PAR right requirements of the plant in question.

Oh and about these posts, I am still AWOL and busy with life, just got some free time during my break between quarters. If you have any questions about these two posts hopefully someone will clarify (bless you hoppy) because I probably won't be around to do so. Happy growing!

Thank you so much. For the first time, I think I actually have a comprehensive understanding of the values and stuff that I am looking at when I purchase or research lamps and fixtures. I really appreciate your simple explanations and examples, but I still have one question left unanswered, this being more application oriented than technical:

Given that the fixture/lamps are putting out desirable PAR ratings at various tank levels, are the color temperatures offered by LED fixtures (designed for reef applications) desirable for planted applications? For example, many LED fixtures are classified by color temp (which I now understand is not the whole story) but it is still the largest chunk of information I have on the lamp at my disposal. So, can I use 10K mixed with actinic LEDs over a planted tank with equal growth and health to what I would see out of a tank that uses comparable t5s of a plant specific color temperature?

Sorry if I made that confusing lol you guys must hate my questions.

Does anyone have any info on the 36" EVO LED 6500K by Green Element??

JoeD323 · 07-02-2012, 04:19 AM

What about the Innovative Marine Utility light? It comes in actinic, 10KK and 65KK. Theres a good chance two or three of these will be my next lighting purchase.

It says 120 lumens per watt on the website but I feel like thats not enough info...They don't say anything about its spread or coverage at x inches over the substrate. Just from fooling with them at the store I'd say you'd need one per 15". Theyre designed for refugium use.

it really help me a lot.

Great info and thank you for sharing

+1

And 36" version too also. After looking several threads I would make a wild guess Ray II 36" DS would be 205 PAR @ 6"??

It's for my 12 gallon and it's height is only 9"... And my substrate is 1.5" thick

They just sent me that data. I'm putting in graph form now. And yes, for shallow tanks it's looking like too much light

This is a graph of data from the first post here. It can be useful for quickly locating LED lights that might work with your tank. Once you do that, you still need to do further research to see if the other specifications make that light suitable for you.

Dude! You are the man!!

Just an FYI. I got this info from another forum(ape). The Aquaray mini-400 65k was measured @14 inches in a dry tank with a PAR reading at the substrate of 55. Not sure if this helps or not but I couldn't get any info from the company or one of the sites that sells this light.

Thank you I updated my chart to show that.

**sayurasem** · 07-24-2012, 09:12 PM

I don't know if anyone ask this before.... 80-120 par are high light. Is there a limit of par for aquatic plants?

jcgd · 07-24-2012, 09:17 PM

I had 100+umol at the substrate and can't get my co2 high enough to prevent stunting in some plants. That's with a sump and overflow, so lots of o2.

Now, that isn't the light saturation point. I believe that is 600umol or more, but dot quote me. In my specific setup, with my livestock, after 130umol a the substrate or so I can't add any more co2 due to negative effects on the fish. I only double my par from the bottom to top because my light is raised so high. I'm not sure how others are running such high light tanks.
