Ganja ,Astir is going to have available those NextGen Sheet Panels ?
For how much ?

Great idea ,as complementary lighting along with HID/CFL/Flouo ...
Without heatsink ,service life is going to drop to around 2-3 years ....
But what the hecK ? If you have them really cheap ....

Or they can be placed directly on the inside of a pc case ....Better there ...
More service life ...And more efficient .......

Well ... Astir seems to have some leds for the masses ....
From really cheap to cheap ....
Maybe soon , Astir will have a "high-end " option ,too ...
....
Just maybe ....

Ha! How many LED's are on that PCB w/o a heat sink? Cheap Chinese stuff? Doesn't run hot at all? That's pretty funny, well played.

When I first made those first gen lights for Astir (....the very first prototypes ...),Merry told me ,that she has her pcbs working w/o heatsink ...
The same ones like the Astir ones ...
"For two years now ",she told me ....
"24/24 ,7/7 -no heatsink " .......
"Leds are fine ...,she finished ....


"Wow " ,I thought then -I remember -"imagine with a heatsink ...."

...
So ,if Astir sells i.e. for 25-30€ a pcb with 24x leds soldered .....
Always customer selected leds ( color-placement ) ,if wished so .......
No extra charges ...
It's not so bad deal .....
One can use them as is for 2-3 years ...
Or place them on a heatsink of his/her own ...
Or on a simple alum profile ....( some kind of Π type profile ,or sliding into rails of profile )
Or simply placed directly on a server box case ,for example ....
Good deal,I guess ....

The only thing I'm worried about is the heatsink core is rather bendable. You could easily mount the heatsink core onto a quarter sheet baking pan with JB Weld for about another $5, though. Slightly better thermal management, perhaps, but more over a much more durable panel. Pretty cool. Wish I didn't waste money on the heat sinks that I used to make mine.

^^^^awesome...........lol who's the guy sniffing your girls^^^^^^^^????
Psu, he is one of my students/friends.

Don't worry about no much talk.. Keep doing what you do.. Many are watching:grin:

What's the temps in there and how do you maintain them?
Ambient temp is 22-25C and water temp is about 2-3 degrees lower. I use a device that blows hot air which operates with a thermostat.

There are 24 leds, same as the Astir panels. They are still under test as cheap complementary lighting option and they seem to work pretty fine.

Just maybe ....
Let's change "maybe" to "soon" :P

Fellow consciousnesses. Prepare to have your mind blown, bent, warped, and enlightened. I just received this product and began listening to the back story http://fivebodied.com/archives/audio/catalog/Bob_Audio/iON/2011-07-29--RnA_Drops_Explained.mp3

You may want to start with www.rnadrops.com for an overview

Question to all

Is this idea feasible?

We ll know you can veg under damn near any blue-green diodes and get pretty far along under WW (~ 4500-5000K), the money maker is >630

Now what I'm thinking may not be on the market, but can it be made at a reasonable price?


A red multichip (used as supplemental lighting for flower)

should be a no brainer to mount and hook to a dimmable driver.

IMHO, a money making kit. Are you listening Astir Grows?,

I'm thinking a 2x 2 area need 10-30w total, so maybe 2 @ 20 on dimmer driver

questions

1. Where to buy just a few (or Astir to develop kits and buy boxes full of multichips)
2. How many watts covers how big an area
3. How big does the heat sink need to be- I'm guessing fairly small

4. Best chip ratio of 640-650-660


Thanks for the feedback

I was thinking a LOT about using Astir LED's(reds and deep reds) instead of pontoons on a 420Par ... thoughts?

I had a custom ratio made up with them of WW and R's, they dont have anything over their 630... :(

Think it was 18:6..?

EDIT Sorry, 16:8

I will say they were unbelievably helpful, redrew my diagram of the 16:8 for a better, more even spread. They were honest about shipping, and very down to earth, straight forward people.

I feel rather guilty not investing yet, but my time in this hobby may be running short..

Well, many things can be done, the problem as in most cases is money, and we are working on a shoe-string budget. Obviously we can do any sort of spectrum if we have the available leds, and once we settle down to our new place we will try all new ideas possible.

Now as to what petflora says:
1. I can't help with that one, in the future we plan to provide also the parts, but now we don't have that possibility to order that large numbers to accommodate that need.
2. That must be looked at, can't even think about answering now :P
3. You're right, I would say the smallest possible. Check out here for various models in the US.
4. I'd try with a 3:2:1 ratio; but that's a guestimate.
