    This bulb is listed as 390mm or 15.4" from the end of the connection wires. The glass section of the bulb is 325mm or 12.8".

  • I have bought Growers Choice double-ended thousand watt bulb and for some reason when I have my Phantom double-ended light to the max 1150 super the bulb turns off when's warmed up. But when I keep it at Thousand watt on my ballast it stays on. Why is that?

    What is sounds like is that the Light Fixture is cutting the power due to it detecting a possible power surge or blowing the bulb. Since the bulb is designed for 1,000 to 1,050 Watts max we wouldn't recommend using at over 1,000 Watt setting on your fixture.
