morsefull Posted September 9, 2016 Posted September 9, 2016 My bulbs blown on my Ashdown ABM C115-500 evo combo (one of the early British made ones) Has anyone replaced it with an LED ? I fancy putting a blue one in but I'm not sure what would be compatible. I read something about having to use a resistor with an LED? Quote
JapanAxe Posted September 9, 2016 Posted September 9, 2016 Quick and dirty calculation: You need to know the voltage that the original bulb worked at (call it 'V') and the current through the LED required to give a good strong output (call it 'I'). The resistance R that you need for the series resistor is found by R=V/I. That will get you in the ballpark. Quote
morsefull Posted September 11, 2016 Author Posted September 11, 2016 Thanks JapanAxe 🙂 Has anyone tried this mod ? Just wondering what LED they used. Quote
bigjimmyc Posted September 11, 2016 Posted September 11, 2016 Buy a replacement from Ashdown. The repair is surprisingly easy. I found the instructions via Google, not sure if they're on BC! Quote
