Gavita Enhanced 600W

Specifically designed for standard electronic, high frequency ballasts.
Gavita enhanced lamps are the grower’s choice for stability, light output and light maintenance. Change your lamps only once a year with these high quality lamps, that have a light maintenance of over 96% per year. 
Their special frame wire construction makes them suitable for standard, high frequency electronic ballasts, but they are also suitable for magnetic ballasts. 
Always make sure that you run lamps at 100% for at least 100 hours to stabilize the lamps, before you dim or boost the lamps. For pro line fixtures please use the Pro lamps, which are high voltage / high frequency.
