Blue LEDs Not Bright?! - GSM-Forum

PhoeniX · 04-13-2002, 10:13

Has anyone bought Blue LEDs from Farnell? I bought the LEDs from farnell and they're very dark? like Midnight Blue... it also looks a little purple in colour.

I was just wondering if it is the problem with the LEDs or do I need to bridge res in 8210? I thought that was only for 3210?

Help..

btw the LEDs part number from farnell was 3225112

hmm.. with the farnell LEDs the whitepaper says that the LEDs use 5V, but I'm sure that the phone uses either 2.5V or something similar?

So there must be a way to bridge the resistors? I heard that the resistors are very hard to bridge on 8210 because it's small and lots of components are close by? Does anyone know which resistors to bridge?

Take a look here: http://www.bluled.co.uk/8210change.htm
In step five you can find informations how to bridge the resistors.

Hi, The LED's from Farnell are only around 6-8Mcd so will never be that bright

The LED's that bluled.co.uk uses are a minimum of 26Mcd's if not more!

Cheers, Laupster

No way. Farnell have super bright ones.

Many thanks in advance.
