Where can one get an incadescent buib that lasts for reasonable time. 50 days, two months etc instead of 2 days, 1 week etc. I know of the light bulb conspiracy story but I am tired of them burning every minute. Fluorescent tubes and bulbs have a very narrow spectrum that makes life look sad. I always use incadescent because their quality of light and rendition of colors is excellent. Advice on where to get reliable ones is appreciated.
