This is a special-purpose bulb designed specifically for lava lamps and certain decorative light fixtures that require both the heat output and the reflector shape of a traditional incandescent bulb. The R39 designation refers to the 39mm reflector diameter.\u003c\/p\u003e\n\u003cp\u003eLava lamp operation depends on the steady heat output from an incandescent bulb to warm the wax and create the characteristic flow. LED or halogen equivalents do not generate the same thermal output and will not operate a lava lamp correctly. The reflector shape of this R39 bulb concentrates both light and heat upward into the base of the lamp globe. The E14 base fits the majority of UK and European lava lamp models from the 1990s onwards.\u003c\/p\u003e\n\u003cp\u003eBeyond lava lamp use, the R39 reflector shape also suits small accent fixtures, display case downlights, and vanity mirror side lights where a compact reflector is needed. The 2700K colour temperature provides a warm incandescent glow rather than the cooler tones of halogen or daylight LEDs. At 30W the bulb draws modest power and generates moderate heat, making it compatible with enclosed fixtures rated for incandescent use. The non-dimmable design is standard for special-purpose incandescent bulbs.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e30W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e180\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eLava Lamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eE14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e2,700K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eWarm White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eIncandescent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use an LED bulb instead for a lava lamp?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Lava lamps require the consistent heat output from an incandescent bulb to warm the wax and maintain flow. LED bulbs produce very little heat and will not operate a lava lamp.
