Guys, please, I'm building a 4 x 4 LED square grid. So, I will build a 25 cm x 25 cm box with 3 separations horz. e 3 vertically. So, in total, we will have a 4 x 4 square grid. (16 squares)
Each square will have a red led. On top, a white-frost acrylic, so now I need to figure out which led will be best. So I get good illumination and also a good view angle, so it just don't show a red dot, but an uniform red square.
Here are some leds from eBay, if you find better ones (only eBay) please let me know, ok?http://www.ebay.com/itm/100-pcs-5mm-straw-hat-Red-LED-Wide-Angle-20000MCD-/120496125516?pt=LH_DefaultDomain_0&hash=item1c0e20f64chttp://www.ebay.com/itm/100-pcs-Red-5mm-straw-hat-LED-Wide-Angle-Light-Lamp-Free-Shipping-/170842661548?pt=LH_DefaultDomain_0&hash=item27c70422achttp://www.ebay.com/itm/100Pcs-5mm-Flat-Top-RED-LED-Wide-Angle-Light-LED-/260520802647?pt=LH_DefaultDomain_0&hash=item3ca83ff957
This leds I already have here, but the V.angle are terrible.http://www.ebay.com/itm/100-pcs-5mm-Red-LED-Lamp-Ultra-Bright-Free-Resistor-EMS-/160557816658?pt=LH_DefaultDomain_0&hash=item2561fddb52
