Are there incandescent light bulbs that are less sensitive to power fluctuations?
By ‘less sensitive to …’ do you mean (a) so that they won’t flicker when the power dips, or do you mean (b) so that power surges won’t blow them out and trash the bulb. If it is (a) then the answer is no – unless you have your whole house on a large power regulator, then there is no way to ensure ongoing and level electronic current that will protect your bulbs from flickering. You can get these regulators, but for an average house you’re talking some serious money. If it is (b) then the answer is Yes, but not for long. There are light bulbs that are sold as “heavy duty” or “industrial” that have thicker filaments (tungsten) and are able to take the occasional power surge without blowing out. That’s the good news. The bad news is that incandescents bulbs as a choice are slowly being replaced by those coiled mercury bulbs which are much more energy conserving. In a year or two, your choice of bulbs will get seriously smaller because incandescents will have been discontinued.
