Deep Blue Solar Flare 115


Does anyone have opinions on this light?

Page 13/36 on this PDF of DB catalog:
http://www.deepblueprofessional.com/...g/dbwebcat.pdf

I want to put it over the Deep Blue 5B, very low tank and long for the height.

I think it might be too much light to be honest, but I don't know of any other fixtures that might fit over the 18" length.

Much appreciated.

That light has too much blue light. Plants need red light also. Consider Build My Led .com where you can diy and led light and they will build it for you.

1 3W Blue LED is too much blue? Maybe you're looking at a different one.

Yes, it may be. Here's why. This spectral distribution chart approximates all white led's and or blue leds. Notice the predominant blue light spike. Remember these led's were designed for general lighting not to grow plants. That a single source led can doesn't mean it's the best option when multicolor led's are an option also
Notice cyan is missing an important part of the spectrum.

There are such thing as all blue grow lights you know. I don't think being blue is too much of a big deal. In fact those cree daylight leds? They are pretty much ALL blue.

Regardless, getting a blue fixture may grow plants fine but they won't look good since everything will be so blue.

The image you posted is of a 14000k daylight bulb which will necessarily have more blue than a bulb with a lower kelvin temperature. The fixture I was asking about only has 6700k and 10000k emitters which should produce a 'yellower' color.

Regardless, I think I might just go finnex at this point since their 18" fixture is about the same price as this DB but it comes with more light and a much better distribution of it.

Both led's radiate predominantly in the blue portion of the spectrum. Why do you think this is true ?

* It doesn't matter. The spectrum of leds designed to look white or blue will look like this
They look the same whether it's 6500K or more. A bigger blue spike makes the difference. See page 5 of this Cree document. The leds in this Deep blue product you want to buy would look like the blue line.

Anyway just remember you have the diy option of Build My Led

Build My LED isn't the only option around, either. There are countless options and far cheaper ones at that. Especially for a low light tank.

You have lots of options (see my 3gal long journal). BeamsWork fixtures are perfect, some of the other LED fixtures on eBay are nice, even Finnex - one of our forum sponsors - has products that are suitable.

I really don't understand this point you are trying to make about too much blue. You're saying that regardless of color temperature there will be a large blue spike... so? In a pragmatic sense, as long as a light can stimulate plant growth and it's pleasing to look at then there's no problem with it.

But you haven't taken into consideration or you don't know plants need certain wavelengths of red light which is just as important for good plant growth as blue light. [I'm sure you seen horticulture lights that output blue and red light.] And you have no idea how suitable this led light is other than trusting the sales pitch. I'm simply trying to make aware single led light sources might a good choice but not be the best choice. That's the pragmatic point. I'm sure this light or any light will be adequate since they do seem to work.

I was implying they could use the diy design app if they wanted.

If your goal is low light, I'd go with the fugeray rather than the ray2.
