"In addition to just HPS high-intensity light (PAR) which creates the most material plant mass, many other plant actions such as seedling growth, plant height, stem thickness, flowering density, plant terpene and essential oil production are all triggered by the presence or absence of certain light colours. Different plant receptors such as phytochrome and cryptochrome control photomorphogenesis. This process activates various plant functions that respond to infrared, blues and UV light which are offered by a broader colour rendering index (CRI) than HPS lamps can provide. These important light colours are supplied by our range of specific, phosphor tuned Pro Grow Metal Halide lamps.\n\nCompatible with all quality digital &amp; magnetic ballasts\nBroad Hertz operating range from 50Hz to 110,000Hz\nPhosphor tuned for accurate &amp; brilliant colour rendition\nLow iron quartz glass delivers highest optical quality\nManufacturer one year warranty from purchase\n\n \nMH - Pulse Start Technology\nPulse start technology increases the efficiency of metal halide lamp to that of high pressure sodium lamps while offering the desirable colour characteristics that only MH lamps provide.\n\nUp to 50% longer lamp life over traditional MH lamps\nFaster cold starts, re-strike &amp; shorter warm-up times\n33% increase lumen maintenance over probe start\n\n \n\nKelvin: 2100\n\nCRI: 30\n\nYield Factor: 100/100\n\nMedicinal Factor: 60/100\n\nColour Expression: Red, orange\n\nColour Description: Dawn and dusk where plants utilise all available light\n\nBest Used: The single lamp of choice for overall plant yield. Highest PAR output. Can be used for all stages of growth and flower, high favouring the late growth period and early to mid flowering period.\n\nHot restrike: 12 mins"
