Hi there,

I definitely want to experiment with some LEDs for my build I have a couple of questions though.

Id be using a 7" screen, so which LEDs would be best ? Which size, which brand etc ? I don;t know much about LEDs, Is it better to use "bigger" ones and less of them ? Do they make bigger ones ?

How many LEDs approx would I need for a 7" panel ?

What would the approximate cost be ?

Are they bright enough to be used at all with some low ambient light ?

Do I need special LEDs or will generic Radio Shack ones work ? Ive read about "super bright" where do I get these and how are they different from "regular" LEDs ?

Any info greatly appreciated.

Thanks
C.

I bought at besthongkong.com 5mm 900 LEDs.
Yes, you need super-bright LEDs.

There are 2 options:
- 10mm into 2-floors (allinbox.com have some examples)
- 5mm in hexagon placement

Hey, I found these on Ebay.

Any good ?

I want to get the array done for the 7" panel relatively cheap, about $250 or less.

Sounds good.

How soon and how much will the 8.9 be ? Im using a 7.2 " wxga panel, will the 8.9 work ?

Are the arrays your selling 10mm LEDs ?

What configuration are they ? Im looking for 10mm double stacked.

How many mcds will the LEDs arrays you are getting have per LED ?

Thanks.

If the LEDs are as good as the ones I mentioned above then Ill be your first customer.

Thanks
