**We have decided to stop selling the Ultra Sun 600w HPS. After repeated attempts to notify the manufacturer of extremely high failure rates (Approximately 20% within the first 6 months).

We believe in selling products that will exceed their warranty period and the Ultra Sun 600 watt HPS does not. There are no problems with the Ultra Sun 250, 400 & 1000 Watt bulbs.
