Choosing the correct Leds

[FIREWIRE]

Im looking to buy leds for my daft punk matrix.

here's where i am with the build -

basically im just unsure of what leds are best for a scrolling led matrix.

I want red defused 5mm but i have to take into consideration brightness and viewing angle which im really not to sure about.

Here is where im looking to buy 5mm LEDs

There is just so much choice that its hard to really decide based on any real knowledge. :wacko

The viewing angle isnt that big of an issue because the surface is curved. The diffused LED is usually less bright than the water clear type. Is the helmet going to be for display or are you going to wear it? If you will be mostly wearing it, then I assume it will be battery powered... buy LEDs with a lower mA rating to conserve battery power. If its display only, then just keep the current draw to a sane level.

Dont forget You can use a higher voltage battery e.g a 9v one if you have room
by putting a resistor in the array of the correct size.
Check out 'LED Array Wizard' on the net. You put in the values and it designs the
array for you.

I get my LEDs here Green, White items in sweetflower8588 store on eBay! they will package up whatever you want at a very reasonable price. I pay about $11 for 50 LED all prewired and with the resistors of your choice already soldered. Never had a problem with them. They convert the $ price to GBP for you, very good service.
