- Energy Saving 15W Spiral Globe with ES Base
15W replaces a 75W GLS globe, so about 80% less energy is used. 10,000 hrs lifetime, so it lasts about 10 times longer than a standard GLS globe. Available in Warm White (3000K) or Neutral White colour (5000K). Energy saving globes achieve their maximum life when they are left on for long periods of time. Environmentally friendly.
