Calling out to Weezard for LED advice

[Weezard]

So,

I finally got word just now. The red 660nm LED's put out 21.7 lumens per LED. The blue 430nm put out 13.7 lumens and the 453nm puts out 28.7 lumens.

Does that sound alright for these? The graphs he sent me before were for LED's that run at much lower wattage.

That's Peachy keen!. :thumbsup:
Especially the 660.
I think you have a winner here.
Mind if I ask what they are charging for the sample?

Yeeha!

Haven't been followiing real close. Long division cornfuses me. But isn't 430nm in the ballpark where they start talking about radiometric power and not visible light? Or is this just a kickass blue that's still cranking out that much visible light?

Looks intriguing, either way. Good find (hopefully!) :thumbsup:

The 90W version with the custom blues was $175, and the 120W with the 660's and the custom blues was $180.

If they work then it's worth it to me for saving me the labor of putting them together!

430nm is in the violet range, just before blue. (violet 380-435nm; blue 435-500nm; uva (longwave) 320-400nm). so i guess the violet and the uva overlap a bit, hence the violet color of a blacklight?

Weezard,

I was just reading one of your posts from page 7 of this thread. Your light puts out 90k on the lux meter? That's AMAZING. The ufo only put out 7,500? That's concerning. How can I expect this 120W light that I bought to perform well at all???

Outstanding! I can't build them for less.

Relax, brah that reading is not impressive when you hold the sensor a few centimeters from the emitter.
At normal growing heights, I run 12K to 75K
91k. lux is just where photosynthesis halts.
That's why you can stop the stretch with a procyon.
What you are actually doing is stopping growth with light saturation.
Changing the R:B without saturation of either color is what give real control of the internode distance
Works well with little girls, not so well with big mommas.
Large plants only stop growing at the top.
Ongoing bottom growth will shove the tops right up agaist the light and then they bleach and will burn with the big emitters.
I built my light with too much red at max so that I could tweak the R:B by turning just the red down.
Look how fast light drops with distance from the source;

If your guy isn't just making up specs, your light will be more than adequate and, perhaps, stellar.

This wait is tough. They said the lights will ship out June 2nd.

Dat frikken slow boat from China always toasts my Taco.

Buck-up me Buck-o, this is the hardest part.
Watchin' dem little girls grow up to be, Lovely Ladies of the Light,
is worth da hassle, and will warm your heart.
I May be wrong, but I'm prolly right.

Building one's own energy input is great fun!
Learning is mentally and emotionally rewarding as well.
But.
Growing is addictive!:jointsmile:

I had to stop naming da girls.

Da sorrow of parting was not all sweet.

Damn I miss Virginia!

Dis be a good time to read every thing you can find about growing.
"All grows are only as good as their weakest link."

With timers, LEDs and DWC,
the weakest link is probably, me.
I automate as best I can.
To mitigate my attention span.

It can get nanometer short, brah!:jointsmile:
My best advice?
Read bruddah, read.:thumbsup:

I've been reading non-stop. It seems that is all that I'm doing in my free time. I've learned a lot however and that is always nice.

The china men are shipping it 3 day DHL delivery so it should be here by friday.

Hey, can you recommend a good place to get good seeds?
