Philips GreenPower LED Flowering Lamps are an energy saving alternative for extending day length or night interruption when cultivating strawberries and bedding plants or producing cuttings from Chrysanthemums and Kalanchoes. This lamp has been specially developed as a replacement for the incandescent lamp to extend day length to control flowering or to break the winter dormancy. The lamps have a standard E27 fitting and are suitable for direct replacement of the lamps in your existing installation, without the need for any modifications to the installation. Three different lamps have been developed, each offering a specific light recipe for different plants. For optimum control, a specific spectrum of light is required for each plant type.
