"We're using these bulbs in outdoor lantern fittings with a PIR and they are providing a decent amount of light but not enough to be a nuisance to the neighbours. The colour temperature is warm and the bulbs warm up quite quickly. They don't look as nice as a regular tungsten or halogen bulb but they use less energy and are more compact than some of the 'enclosed' equivalents (e.g. product 66890). So far the bulbs have been reliable, but I can't yet comment on the accuracy of the 10000 estimated lifespan."
