Slow Start
Existing conceptions of light bulbs
Other products not adapted
The Tide Turns
Environmental concerns among consumers
Improved technology
Power strategies from legislators
Switch to a New Technology
Cowan and Hultén (1996) identify six mainfactors that could possibly evoke an escape from an existent lock-in or completely unlock a market.
1. Crisis in the existing technology
Conventional bulbs still serving their initial purpose
But relative/perceived efficiency decreased
2. Regulation
Very critical factor for the future of the light bulb market
Governments to promote the use of CFL or even ban incandescent bulbs
3. Technological breakthrough producing a cost breakthrough
Higher retail price
But a cost advantage in the long run (life duration and low energy consumption)
4. Change in taste
Crucial factor
Consumers increasingly concerned about environmental issues
More and more prefer environmentally friendly products
5. Niche markets
Of minimal importance
No big niche for the CFL bulbs
Few early adopters
6. Scientific results
Innovative technology enabled the invention and production of CFL bulbs
This knowledge put “pressure on the old technology” and questioned its efficiency.

Future Outlook
Two paths have been taken that may create a future CFL lock-in:
Adapation by retail Laws
