BIG differences between the performance of the two samples did the last of our bulbs claiming up to 150 per cent more light no favours. The difference could be seen with the naked eye in the tunnel, where the hot spot on one of the Alite bulbs was smaller than the other. That was reflected in the beam assessment, where there was significantly less light on one bulb in the more-than-20-lumen area. Peak brightness was more consistent, but it was no match for the best and was at the bottom of the results table. It was close to the top performers in the 50 and 75-metre tests and is currently enjoying a discount at Halfords.
