Tired of blowing high-end HPS lamps? The NEW Lumatek Bulb is specifically designed to work with the higher firing rates generated by ALL digital ballasts. Guaranteed for optimal performance, these high-par output lamps have strengthened seals and a reinforced arc frame to ensure that they provide long-lasting performance with stable lumen output.
• Initial Luminous Flux (lm): 92,000
• Luminous Efficiency (lm/W): 150
• Color Temperature (K): 2,050
• PAR (umol/s): 1030
• Photo Flux (phyto-lm):185,000
Many HPS lamps, including the 600w Hortilux, have been designed with a 1500-3000 volt ignition pulse (aka firing rate). Digital ballasts use a 4000 volt ignition pulse which will fire these lamps at first, but the higher starting voltage degrades them quickly and eventually they will fail to work.
