The panel or meter based products work to ground surges to earth which I presume was about 10 feet away. This provides excellent protection by grounding the effects of potentially deadly surges before they can get into your home and then find their own, unique ways to ground like your microwave, Plasma, toaster, etc. However, there is still going to be some voltage let-through which can be effectively dealt with by point-of-use devices such as those from Monster, Panamax, Belkin, Tripplite, APC, or whomever. They can further throttle down the residuals to essentially harmless levels.
You haven't indicated if you also dealt with your incoming cable and phone lines. If not, that's also a point of ingress and it's not terribly expensive to buy and DIY. If you need examples, ask.
IMO, if you're concerned about bulb life as a result of frequent power outages, then you'll need to determine things like power draw, run time, and so forth in order to be able to source a UPS that'll handle the job. As AVDoogie notes, questions should be asked from the vendor as to how the unit operates in a pass-through mode to get a handle on whether signficant distortion or AC waveform alteration occurs. You might find that the costs outweigh bulb replacement but that's a personal call on your part.
