The Neco 5W LED "GLS-Style" lamp is a direct replacement for any 40 watt incandescent or 8 watt compact fluorescent lamp with either an Edison Screw or Bayonet Cap fitting. The lamp is cool to the touch and emits a beautiful warm-coloured hue. And compared to compact fluorescent lamps, it has no warm-up time, no flicker, no mercury, and it will last 3-4 times as long. It will also save you energy - up to 80% compared to a 40 watt incandescent, and up to 30% compared to a compact fluorescent.
