as per latewood,
For HID lamps. (Metal Halide-MH, High Pressure Sodium-hps)

1) Place your hand (palm down) at top of canopy.

2) Lower light until you cannot stand the heat for a full minute...once that distance is determined...

3) Raise lamp 2" and keep that distance consistent throughout grow.

Note: Always have a fan dedicated to the airspace between the lamp and canopy, and you will be safe. An oscillating fan is necessary to circulate air.
