I bought the Lidel reflectors before Jerry had his available. I asked him when I placed my order for cobs and drivers and even suggested he make his own...
I got some of the new reflectors from Jerry. $0.80 per reflector.

If you don't use it on your panel...you should recycled it to make pies...lol
It look like pie mold!
I will buy some soon too...but I'd like to know what area a cxb3590 @1400mA can cover with this around? I mean what size is the circle of light at 12 from the canopy...?

Well with the reflectors, they really keep the light in a very tight space. The angelina like he has, isn't measured from the canopy. There could be any amount of space below that. But a foot from the ground would be like a 8-9" diameter I'd say?
it's a 90° reflector, use your math, geez

This is my LED tower I built for the light source to a vertical cylinder grow unit I had made years ago. I powered it with a 400watt HPS at first, to much heat which lead to many other things.
There is 132 total LED's used, 8 blue, 8 royal blue, 8 turq., 8 true violet, 8 CW, 8NW, 24 WW, 24 red, 24 deep red, and 12 far red. I broke them down and have individual constant current drivers powering them, all drivers are located outside the grow room above the ceiling. This plant was just getting my hands wet again and to see what the grow room and lamp worked. It was a male and so the .pic was taken as I was taking it out. This system was designed to be used with 3 female cuttings from the same donor for a more even control growth of the plants around the screen.
It is not perfect, need to figure a few things out before next grow attempt.
Biggest concern I have is the secondary lens or reflector's... are they needed........ or a light diffuser panel- something that mixes the light rays up.... LEDs are 8 to 9 inch's from the plant.

Geez...have ever seen him???...lol (I am like saint thomas...I only believe what I can see!)
Could explain the math...as I said before...a lot...me and Mr Math are not in good therm...not really calculate but formula are not my cup of tea...!
So I guess it is ok for a square foot!
But the thing I want to know is: which reflector angle only cover 1 sq/ft!
When I will have one over each sq/ft @1050mA I want it to only cover 1sq/ft no where else cause there's gonna be another one for each of the others sq/ft!
Please enlight me...lol!

Shipping costs? I would hate to buy a dozen at just under $10 and pay $40 shipping??

Ask him for china post shipping, it's more reasonable.

I remember him saying not an option anymore, but maybe for cheap stuff he will still do ti?!?
you have a right angled triangle, with the right angle on top, a and b have the same length, as alpha and beta are the same and you know your height h
beta = 90° - alpha
p = h/tan(alpha)
q = h²/p
c = p + q
a = sqr(c·q)
b = sqr(c² - a²)
u = a + b + c
A = c·h/2

I bought 6 CXB3590 3000K 36V COBs at the same time and some holders as long as I was going to be paying shipping costs anyway. I think I got 16 or so, so that I have more than I need now and have a stash for replacements or future projects.

That table looks right. I used 90 degree reflectors on a couple of Vero 29 COBs and the light spreads out fast. It is only when you put hour hand a couple inches under the reflector that the light is very tight and concentrated. A foot or so below the reflector the light is well spread out.

What to eat Pescetarier?
Pescetarier give up meat, but eat fish and seafood. Specifically, they do not eat meat of warm-blooded animals, including beef, pork, poultry & Co. include but only by cold-blooded animals such as fish and the most invertebrate seafood. They are thus a specific group of vegetarians.
