Model SDS-V-2014 ( " Stealth " ) is almost finished ....
(A tad of paintjob left ...)
And now the "space"-"grow-area" that this light was made for ,first hand ...
33 inches wide x 22 inches deep ( ~ 5 sq feet , ~33 W/sqft at 2100mA )
A closet ...
High ...Fashion .....
And of course a D.I.Y. active carbon filter ,to go with ...
(Actually,it used to be an truck engine oil filter ....
...)
Cheers ..

Setting the driving range :
Min
Max
Spec at max ( 2200mA / Tc= 50°C)
( From a 430 W Agro ,Rad efficiency is 30% ( .3 or 300mW/W ) .
http://www.usa.lighting.philips.com/connect/tools_literature/downloads/p-2707b.pdf
-CXA3070 AB bin ,has just a bit better efficiency at 2.2A ,than a plant growth -oriented HPS.
-Does the better light quality from CXA 3000K has to be mentioned ,also ?
-Should we talk about the safety ? (HPS inside a wooden closet ?No-no-no ...)
-About the total cost of built ?
(Less than the price of an average quality digital HID ballast ....)
-The service life and 'stability' of performance ?
....
Cheers!

So,if with 0.3 radiant efficiency ,the 430 W Agro ,will be resulting an 1 gpw .
(Everything has to be pretty dialed in ...)
So ,about 430 grams ...
I'm "curious" to see what 174 W of solid state light can do ..
At about same rad . efficiency ...
I guess ,it won't take long to find out ...

Well Mo,actually I do not own a camera ,or a compact digital photo camera that has video shoot function..
(only my trusty Olympus SLR .)
......
Still,I've managed to shoot a vid-specially for ya !
-using my laptop's build in ,web camera.Most of vid's ambient sound is comin' from the laptop's fan ....
..Still ,I think you'll get a rough idea..
In real,the fixture is more stealth -regarding noise/sound ,than stealth itself !!!
The only thing ,I can actually hear,is the 'hissing-whistling' of drivers being dimmed !
Cheers.

You put a knight rider light. 
It's the little things..

LOL!You put a knight rider light.

Actually "Knight Rider " leds go :
Vooozh >>>>>>>>>>>>>>>>
Vooozhhh<<<<<<<<<<<<<<<
This is not a KR ...
It's a 'chaser " .
It goes only one direction :
<<<<<<<<<<<<
<<<<<<<<<<<
And actually ,is a fan speed tachometer .
It would change freq of 'chasing' ,if the fan 's speed was adjustable.
Now,it serves as "FAN OK " indicating light .
Details ,sometimes ,make the whole difference ...
( But that "led chaser" ain't one of 'em ..I just like it more ,than just having a 'constant ON " indicating led ..)
Cheers.

A lovely job, if only I was so talented. Mine look like an electrical nightmare.

Yeap...
The external fan ( TITAN 120mm 12 VDC / 0.11 A <25 dB ) is there to blow gently some air to the young plants
and later rather to circulate the air .Quite silent fan also.

Not any special talent,here ..
Trust me on that .
....
Commitment.
Give 101% of self to make dreams become reality .
..
Come to think more about it ...
...
Actually ,is everybody's power.
To explore .
To learn.
To create.
Only difference is the level of awareness of such power
and the commitment to dreams ...
Kinda of poetic,maybe ?
Nevertheless ,remains a hard fact and a solid truth ...
Cheers!

I STARTED JUST TO BUILD A GOOD LIGHT THAT WORK'S, NOW I'M THINKING LOOKS AFTER THE FACT. Maybe I'll try to beautify for my next project. I will eventually upgrade to new cobs when they come out with CXA BADASS.Not any special talent,here ..

Yeap ....Usually ,that's the way " it " begins ...
Personal first -'working'- LED build ...
Spring 2012..(posted on RIU at Sept. 2012 )
Sure ,not much quality ,there ..
But it worked ...enough ,at least ....
....(640 nm -NW 5000K 70CRI- WW 3000K 80CRI ,all cheap 8mm plastic cased ,
22-24W per panel.Plant shown is under ~70 W )
Cheers.
