Brand New High-Output 250 watt High-Pressure Sodium bulb is rated at 33,000 lumens! Standard 250 HPS bulbs only emit 27,500 lumens. Life expectancy is 24,000 hours. The 250-watt HPS bulb is a very popular bulb used by the indoor hobbyist grower today. With very little lumen loss over its lifetime compared to Metal Halide bulbs, you can expect only a 10% yearly decrease in lumens over a bulbs 3 year (24/7) lifetime. Compare that to Metal Halide where as much as a 50% decrease in lumen output over it’s shorter lifetime and initially lower light output than HPS and it is clear to see why the HPS is so popular. It is believed the HPS bulb’s bright “yellowish” spectrum mimics that of the “harvest sun”, triggering plants to develop flowers rapidly and abundantly. You can expect excellent results using this HPS bulb and it is good for all stages of plant growth.
