You decorate, you clean, and there's still an element of Dickensian drear in the corners of your rooms. Aha! Light-bulb-overhead moment: Trade in your regular light bulbs for GE Reveals, which give off a crisper, more vivid light that doesn't make you look washed out. The secret behind these powder blue bulbs is neodymium, an element that filters out the dull yellow cast emitted by ordinary incandescents. The bulbs are $3 to $4 for a four-pack and are available nationwide at home centers, hardware stores, supermarkets, and drugstores.
