  • Designed specifically for 27-inch Grande Lava lamps
  • 100-watt incandescent output restores full lamp brightness

Direct Replacement for 27" Grande Lamp

This 100-watt incandescent reflector bulb is manufactured specifically for the 27-inch, 250-ounce Grande Lava lamp. It restores the proper heat output when the original bulb dims after extended use. The single-pack format suits owners who need a single spare or immediate replacement.

Wattage and Base Compatibility

The lamp requires exactly 100 watts to melt the wax and create the signature flow motion; lower-wattage bulbs will not generate sufficient heat. This reflector design directs heat upward into the globe, matching the factory specification for the Grande model. Using any other wattage or bulb shape will prevent the lamp from operating correctly.

Simple Installation in Existing Fixture

The bulb measures 2.5 by 2.5 by 4 inches and weighs 0.1 lbs, fitting the standard socket without adapters or wiring changes. No tools are required — simply unplug the lamp, allow it to cool, and screw in the replacement. It frees the owner from searching for generic bulbs that lack the correct reflector geometry or wattage rating.
