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

I have not see anyone mention that bulbs are made to hang vert or horz so check your bulb first before changing its orientation. They both work and there is very little difference to lumens output or intensity.

Use which ever works best for your lay out. Cooltubes are the shit though, my room dropped 12 degrees using them.

Good Luck

The hortilux blue 400 watt metal halide comes in a vertical version.

Riddle me this batman:

You hang a bulb verticle and it's light is emitted 360 degrees.
You add a reflector (usually horizontal) So the same light being emitted is now at least concentrated to 180 degrees.

So how can a buble without a reflector have better penetration?

You can say that a non reflected verticle bulb gives better coverage area but not better penetration/lumens.

also look for heath robinson and his vertical grows. mind blowing
