Sunleaves VitaLUME Compact Fluorescents efficiently deliver a full spectrum light comparable to the wavelengths found in sunlight. These low-heat bulbs can be placed close to plants to maximize light exposure. This internally-ballasted 125-watt "warm" VitaLUME produces a color temperature of 2,700 kelvins to promote bud set and flower production. Customers can pair this VitaLUME with a non-ballasted Sunleaves Comet 125 for superior results.
