Color Temperature



How much does the color temperature of my lights matter?

I love the photo, but it totally made me think of this:



Sorry to be off topic, but the thought made me laugh.

Depends on who you talk to. Reefers think red light (warm light) encourages algae. FW say blue light (cool) does the same..

Color temp def. effects how it looks to you though..
Plants can adapt to a wide variety of spectrum temps...

lolol...that poltergeist poster and the op cannot be coincidence.
Same polka dot dress, same hair, same hands, same white light in the middle darkening towards the edges...

Acro nailed it

I've come full circle...is that good or bad?

Color temperature makes a HUGE difference to me. I hate the color shift that low numbers produce. Personally I prefer the 10000k bulbs. To me they really make the colors of the plants and the fish come out. As far as plants and color temperature, I don't think they care so much as long as it's not so far to one end or the other of the spectrum.

I now mix 10K with Full Spectrum on all my fixtures.
4 to 3 ratio of 3 watt LED's.

Significantly better growth for me than different channels of fixed colors.

You dropped the ww from the array??
Adding it sig. improves CRI..not that that matters to growth..

The WW Led's were all dropping like flies.
They came from China, running on LDD drivers, all 10 of them have failed.
I was only out $3 including shipping.
Every week 1 or 2 would fail.

Very strange failure for me.
Usually LED's short out when failed, reading under 4 ohms.
These failed with strange values over 1K ohms.
I'll just call it a bad batch and move on.

I will need to update my other thread with PAR data.
Purchased the Seneye and have only used twice to measure PAR.

The 10K with Full Spectrum are more appealing to the eye too!

no I've had both ww and cw die like this..
I suspect they can't take over 500mA over time.. Even the "3w" ones.
Or they just mixed up 1/2W since it isn't really a "real" number anyways..

Finally got tired of replacing them and went w some eek bay Luxeon Rebels..
So far much more "stable"...Picking the right vendor they come out to about $1 a piece though.


so far so good...

Sarting to work with a combo of Fluorescent and LED

I set up a 29G this year and put in a Hagen "flora-glo" (2,700K) in the existing hood, and augmented it with a Marineland 21" "hidden" LED, which mounts on the front rim. it is 6,700K).
I am not sure if the 2,700 K flora-glo penetrates deep enough, and I am switching to the 6,700K "Life-Glo" still in combo with the LED, mainly because the Life-Glo puts out a lot more lumen (ca 2.5x as much).

I am doing the same arrangement in a 10G tank.

It will be very telling once I get a month in my main tank after I switch from the Flora-Glo to the Life-Glo. I am light on fish (a betta, 5 Amano Shrimp, and 7 Aeneus Cory, and 1x Pygmy Cory), and ammo, nitrite, nitrate are invariably zero with healthy plant growth.

Plants don't care about lumens..
Flora glow spectrum..and why it is dimmer to you but not plants..

Life glow:

It is a nice visual bulb..and really like the added cyan.

Believe from plant perspective,PAR values are more important than spectrum.
For my eyes,I like a 6500K /10,000K mix.
Currently running an old four foot long Aqueon triple tube T8 fixture that has been discontinued over an 80 gal low tech tank.
Using two 6500 K bulbs and one Zoo med Reef/sun bulb all 32 watt.

Matters to my eyes a great deal, to the plants...not so much

I like heavy blues and reds complimenting a base range of 6500K or so, plants seem to like it too.

Current arrangement in my 4 bulb unit, f2b

Plantmax 3000K
ZM UltraSun
ATI Purple
TrueLumen Flora
