8ft 330G Construction Has Started (Pics)

[dme330i]

Bill,

Since everyone is close by, I'm sure we can do it again. It was convincing enough that Dave decided to try and order the components to do his 300. Pic doesn't do it justice. It's a very crisp, bright white look.

Jon

I'll try to recall the numbers. I was holding the light over the tank, so I wasn't able to write anything. Mike, Dave - correct me if I missed the numbers. Ignore the purpleness.

PAR meter was unable to read just above the surface.

Just checked with the usual suspects in China, the high power LEDs typically emit in the 465-476nm range for "actinic".
While our normal actinic range is more 400-420. (closer to UV)

I'd be interested in a Bill comment on that - He knows more about this than I can ever forget...

Yup the Led's Jon has rocks!!!

After testing the 50 watters this evening at Jon's, I’m convinced this could be a good replacement for my MH's on my 300. His led's displayed awesome colors and the PAR readings were simply outstanding. This was even without and having any optics installed. In fact, I was so impressed, I'm in the process of ordering all the necessary hardware to build a test my own led lighting system with the same 50 watt led's that Jon has.

Bill I know you and I discussed the future of led's and the fact that they haven't perfected the technology as of yet and there's still cost factors. I'm telling you, after experimenting with your led's in my basement several weeks ago and now seeing first hand what Jon has. I'm so convinced that led's have arrived that I’m now willing to bite the bullet and start testing them on my own system

I've seen several members on this forum and others, buying and then turning around and selling the same unit’s weeks after they purchase them. I was finding this a bit discouraging. However I'm convinced after consulting with you, Purplegorilla, Ryan from ReefWorks and now seeing Jon's system in person, that there is hope and with the right combination of led’s and having the right spectrum, one can achieve good growth, lower power costs and also be happy using led's.

The color combo that Jon has was certainly pleasing to my eye and the numbers he posted are pretty much as I remember them.

 

[reefkeeper]

Sorry, I forgot to mention GiulianoM. He's been a great resource also.

Edit: Yes, the color comparision next to the evo light Jon had in his cube was extremley different. The color with the 50 watter 455nm royal blues was crisp, a bit whiter and simply outstanding

Edit: Oh, and those readings were from just holding (1)20k and (1)455nm led's over the cube and then taking the readings. A total of a 100 watts.

Sweet!

I will have to test with my 10,000K and 455nm combos once I have things set up...

 

[dme330i]

While I've only been focused on PAR and the visual "look" so far, I've been wondering about the spectral range of the combination. Anyone have a way to measure this?

 

[rdnelson]

Jon, I got your e-mail but haven't had a chance to do anything with it yet. I will work it up today and get it too you. Thanks,

 

[giulianom]

We need someone with access to a spectrograph or spectrometer... And they're not cheap, I think.

I may be investigating how to DIY a simple spectrometer... :D

If anyone's up for it and will do a great job, you'd be the one. Keep us posted. :)

 

[reefkeeper]

I wish I had the time to play with this myself. This looks real cool!!

I'll look into this...

great size tank. very impressive so far:thumbs:

Facing for the stand is coming along. Middle parts are stained with first coat. Second coat will bring in some reds. The canopy fronts are up on top.

Base structure again:

So finally finished the staining, then sprayed on the poly. Turned out pretty good. For frame of reference, the sump on top is 110 gallons.

Hoping the basement will be finished within the next couple of weeks. Got a lot of pukani cooking too.

Sweet. Liking good.

Looks real good.

I'm new to the forum. Been a treat following along. Very nice. I've got to try my hand at making a canopy hope I can do as well.
