LONGSTAR is one of the largest and well established CFL / LED grow light manufactures in the world. Known for absurdly reliable lights for every application, LONGSTAR has become recognized internationally as one of, if not the leader in the CFL grow light industry worldwide.  LONGSTAR'S powerful spring 6500k compact fluorescent light bulbs incorporate proven LONGSTAR performance into a small, more efficient design. Resulting in much better lighting performance and extra long lamp life. All lamps feature end of life circuitry that shuts the bulb off automatically if it senses any lamp starting issues or shorts. The ultra high efficiency electronic circuitry optimizes while improving overall bulb performance including lumen output.  Improved lamp design provides more lighting surface area in a compact space for cleaner more intense light output for plants, aquariums or photographers. DO NOT be fooled by companies & individuals selling 5,500k bulbs as daylight or spring spectrum bulbs. Those bulbs DO NOT provide the spectrum's plants need in the vegetation or spring cycle like the 6,500k spectrum does. These are true daylight spectrum lights.
