Default Feit Par30 LED

I already own this.

http://www.amazon.com/Feit-Electric-.../dp/B002Q8H99O

Quote:
5 High- powered LEDs 490 Lumens 3000-3200 Kelvin
And I was wondering if this would grow plants of any kind?

The Kelvin ratings pretty low and the Lumens aren't that great, so I assume the answer will be no or low light plants.

Thoughts?

You want a fixture that produces lighting that's at least 6500K in color temperature.

This is not true. 2300K, 3200K, 4100K, 5000K, 6500K, 7500K, 8000K, 10000K... I've grown lush plants with all of them. All you need is enough of the kind of light you are providing.

My personal preference is 4100K, smooth spectrum.

I'm not sure why this 6500K "rule" keeps being passed around. I'm guessing it's marketing.

Cheers,

I agree that higher kelvin would probably be better and more appealing to the eye.

I agree with you too. The light just looks very orange.

And then the real question is whether the par30 I own is enough light?

If you try to light a 6 foot long tank with it, it won't work well. If you try to light a 2 gallon nano tank it probably won't work well. What are you trying to light with it?

Not really anything in particular...

I just happen to own it already and was wondering if it would be of any use in ANY application

I neither say it was a rule, nor that plants couldn't be grown with lighting of another color temperature.

6500 = pretty nice, average, appealing to the eye. People recommend lighting in the 6500k range purely because it appears fairly natural to the naked eye in a tank.

When someone is new to lighting, most people in this hobby try to steer them toward something that looks a lot like natural daylight. As the OP said, their light looks orange/yellow.

I'll try and get some pictures posted of the light in action.

$35 is a lot of money for less than 500 lumens.

I wanted to update...

I'm getting good growth from Caulerpa and I added some Chaeto to my pico as well and it looks pretty good so far.

I'm impressed that the bulb can grow anything lol.

I suspect that I may be able to even grow some low light corals with this thing.

If I ever take down the saltwater pico I think this could grow at least medium light plants... but then again I could be wrong >.<

If I find out anything else I'll update the thread again since I think I'll only be able to find my answers through experimentation.
