* LVD Induction Bulbs vs. Other Types of Bulbs

* The LVD Bulb is Superior in every regard to any other light bulb technology. While high pressure sodium is extremely energy efficient, the light color is not optimized in the human visible range, so although a light meter will register more light, the human eye will detect twice as much light from the LVD bulb compared to a high pressure sodium bulb.
