Integral 9.5W E27 R63 LED Designed to produce minimal heat & maximum brightness but consume very little power, this 9.5W R63 LED Reflector serves as a direct, retrofit replacement for grossly inefficient 54W filament & halogen reflector bulbs. You'd be forgiven for mistaking this bulb for those it is designed to replace though, with a frosted, anti-glare refactor both obscuring its Everlight LED components & diffusing the warm white light they produce evenly & effectively. This enables the bulb to retain a reassuringly familiar aesthetic but offers all of the benefits of LED technology, from increased efficiency & longevity to cooler running temperatures & drastically reduced energy costs.
