Our original LED Calculator was coded by Rob "Linear" Arnold who has since left bit-tech to run his own modding website, Linear1.org
Regrettably, despite its HUGE popularity, the backend of our new-look website won't allow the kind of raw PHP that was required to run Rob's LED calculator, and thus we were unable to convert it from the old website for you to use.
However, all is not lost: Rob has created an LED Calculator
on his new site, and we encourage you to use it there instead.
Apologies for any inconvenience caused.
