Read the batt drain thread in the FAQ section.
If yu had a drain of 0.05Amp, that equates to 0.6watts. Certainly not a 5W light!
More likely to be Electronics related.(BCU etc)
Not sure what you mean mate. Yesterday he said he got 0.05A and i reckon that's fine..
Today he said he got 0.4A which is 4.8W so 5W light, (he probably left something on)
