The bulb produces 550 lumens at 2200K, a warm amber tone lower than standard warm white (2700K-3000K), creating a soft glow that replicates early Edison-era incandescent lamps. The gold tint on the glass envelope adds to the vintage aesthetic when the bulb is off and intensifies the amber cast when lit.\u003c\/p\u003e\n\u003cp\u003eDesigned for decorative pendant fittings, exposed-bulb table lamps, wall sconces and chandeliers where the bulb itself forms part of the visual design, the ST64 shape (64mm diameter, 145mm height) suits larger lampshades and open fittings. The 320-degree beam angle provides near-omnidirectional light distribution, making it suitable for general ambient lighting in living rooms, dining rooms and bedrooms. The dimmable function allows brightness adjustment from full 550 lumens down to a low glow, compatible with most leading-edge and trailing-edge dimmers.\u003c\/p\u003e\n\u003cp\u003eAt 5W consumption, the bulb replaces 40W incandescent equivalents, reducing running costs by approximately 87% over the bulb's rated 15,000-hour lifespan. The E27 base fits standard UK Edison screw lampholders. The Energy Rating E classification reflects the 2200K colour temperature, which produces fewer lumens per watt than cooler white LEDs, but the lower energy rating is offset by the reduced wattage compared to incandescent alternatives. The gold glass finish and filament design remain visible when dimmed, maintaining the decorative quality at all brightness levels.\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\u003e0.05\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e550\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eST64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eE27\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e2,200K\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\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e320\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable and what dimmers does it work with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the Energizer ST64 is dimmable and compatible with most leading-edge and trailing-edge dimmers.
