Query: Buy a 150w HPS instead

I used this light for 9 months before the bulb burnt out with my biggest complaint being it doesn't produce nearly as much light as my sun system 150 hps (8,000 lumens vs. 16,000). Then I went shopping for a new bulb and realized this is where the 150w hps wins hands down. The Feliz 125 CFL (6500k) I found was $40 plus shipping while a new Ultrasun 150 is $15 plus shipping. So for more than twice the price you get half the light. If you're worried about vegging in the red spectrum, don't be. The lumens per watt and cost savings on bulbs more than make up for it.
