I want to know the answer to the following question:
What company first marketed light bulbs using the reflective capsule technique to increase energy efficiency?
All the background I'm provided with is that "The "Halogena Energy Saver" incandescents can produce about 23 lm/W; about 30 percent more efficient than traditional incandescents, by using a reflective capsule to reflect formerly wasted infrared radiation back to the filament from which it can be re-emitted as visible light.". Is that enough to answer the question?
Answer: no
