Note that the Halolite bulb is only 8000 hours life (as, I note, are the Megaman GU10's in B&Q... they don't half mark up...). I also note the Halolite is "cool white", which will be harsh compared with halogens. I would always recommend going for a "warm white" bulb if being used in the home, as they are only a little whiter than standard halogens (and you very quickly get used to the light).
