At the risk of getting back to incandescant bulb applications - The low wattage powersavers are okay but I'm not convined they are always as long lasting as claimed.
True incandescent globes come in two grades - the ordinary ones, from Bunnies - not bad value but they are not much good in applications where there may be some bumping such as in the power light in the garage or table/standard lamps where the may well be some shock. The best in this application have an additional specification "RC" which stands for reinforced coil. They are designed for this heavier duty.
