When safety is a concern, shatter resistant light bulbs are the only option. These bulbs are silicone coated to prevent glass shards from contaminating food or creating other hazards. The Precision Lighting 25A15/TF bulb is equipped with a heavy-duty 130 volt filament, allowing it to last longer when operated at 120 volts. Appliance light bulbs have specially reinforced filaments to prevent premature failure from frequent slamming of refrigerator or oven doors.
