What happens to the projection bulb when there is a power interuption to my home? Since the cooling fan would then quit, will the bulb and areas around it be harmed? I'd hate to face a $300 bulb or fixture replacement every time we have a power outage in town.
A power back up unit will allow power to be miantained for a somewhat short period of time after a power outage, or maintain power in the case of brown out coniditions. Several models can be viewed at your typical officedepot, officemax,staples and the like. These devices allow for a controlled shutdown. Other devices involve power conditioning/linefiltering. Two manufacturers that discuss some details about these issues include Panamax, Brickwall, and APC.
I think if you read up on these companies products, your knowledge level will be where you want it to be as far as consideration for protecting your equipment from power issues if you have concerns.
UPS - Uninteruptable Power Supply - A.k.a. - a small box containing a battery that will output 110 volts. Depending on the size and price and the number of devices attached this device can support computers and elections for several minutes to possibly hours. Most home solutions are under a $100.00 and will support power for 5 to 20 minutes.
