Can a Q1 be upgraded to a Q3 by changing the led?

Hi all,

I just got a Q1 from CPFer blademan and was thinking of changing the led to a lux 3 using the same circuit board. Is this effectively changing the Q1 to a Q3?

Also, are the dimensions of the two exactly the same? I.e. can i use viren's copper heatsink to DD a lux 3 in a Q1 body?

TIA

TIA :

Q1 uses R020 resistor whereas Q3 uses R050 resistor. But same cicuit board.

Same size of circuit means that you can use ViReN's Cu heatsink both models. And I am using it with R123 in Q3 now.

Warren,

so does that mean what i am planning to do isn't a problem?

Yes, if you DD without circuit component, it is OK. Just take away all component. see this

It isn't a problem if your up to the task of removing a very small surface mount resistor and installing another in it's place. You would need a steady hand and a low wattage soldering iron that has a very fine point tip. Working with small surface mount electronic components requires thought and preparation and can be somewhat frustrating at times. Try un-soldering and re-soldering a few surface mount resistors from an old circuit board first to determine if your comfortable working with these tiny parts. It's not everyone's cup of tea.

Thanks for all your help litemania and lumenhound. You have made my day. /ubbthreads/images/graemlins/smile.gif
