  • ENERGY EFFICIENT FLUORESCENT LAMP
    Publication number: 20090058312
    Abstract: To decrease a power consumption of a fluorescent lamp, the fluorescent lamp is provided with a high efficiency fluorescent coating, generating more light upon receipt of a conventional amount of radiation. Decreasing the power supplied to the lamp decreases the radiation supplied to the fluorescent coating and thus the light output of the lamp. Due to the increased light output of the fluorescent coating, the light output level of the fluorescent lamp may be kept substantially equal to a light output level of a conventional lamp.
