These opaque amber C7 replacement bulbs are what the well-dressed house is wearing this season. The opaque color resists fading and hides the incandescent filament giving the lights a warm soft glow. At only 5 watts, the bulbs use less energy, while their 120 volt filament lasts longer giving you 3,000 hours of trouble-free lighting. They come economically packaged 25 to a pack and are UL listed for indoor and outdoor use. This holiday season paint your home in the classic, soft light of Christmas light bulbs.
