Looking for a solid business name / company name for a company whole-seller of energy-efficient light bulbs and lighting fixtures. I would like the company name to give an impression of a serious, established international business. It would be good if the company name contained the words "light" or "lighting".

Requirements to the name: it must available as a .com domain name, and as a user name at popular social media sites (Twitter, Facebook, Instagram, etc.).

Any creative ideas are welcome :)
