Q: Should my HID lights hang vertical or horizontal for maximum penetration?

A: Studies have shown that a horizontal positioned bulb and reflector unit will provide superior light penetration to a garden compared to vertical orientation. However, both styles are acceptable for cultivation.

Q: My bulb, ballast and reflector combination is not working. How can I fix this?

A: The problem might be a bad connection in the mogul socket. Make sure to disconnect the unit from the power supply, and then look inside the mogul socket for a metal tab. Pry this tab upwards a little bit to make better contact with the bulb base.
