Or, for extra light, join the red and green together, to the non-earth wire.
Graham, have you actually tried this or just surmising?
There are 4 LEDs, and I checked that all 4 light up when connected either with the red (=1w) or the green (=4W). Connecting both made no difference to the max output on mine.
Yes, I did just tape up the red wire out of the way.
