Tom - my original post many moons ago is
here but the pics and links aren't working properly
I think it was from
www.ultraleds.co.uk and they're the
6 LED white ones. They look alright but half the LEDs seem to fail after about 3-4 months due to the heat from the main bulbs. Not an overly cheap habit to maintain at about £6 a go...
Rip3z - look at where the light beam stops on the tree in the middle and the building on the left - it appears more 'defined' and less soft-edged than the standard bulbs, but I do admit that I could have done a better job with the photography...
The main difference seems to be the light on the road in front of you - seems so much brighter than before!
edit: I notice that my slightly less than favourable review of the sidelight LEDs, pointing out that they fail, seems to have 'disappeared' from the ultraleds site...
