400 MH and 400 HPS at the same time?

Light waves that combine can double their amplitude or cancel it out, or anywhere in between. All electromagnetic waves are subject to interference.

I'm not sure, but I think you're wrong.

I think you're refering to the "double slit experiment".

Two EM waves (electromagnetic) can't be added together to create a greater amplitude.

By the same token, they don't "interfere" with each other, and create "interference patterns".

Yea, I am. The double split experiment proved that the light waves were interfering.

Type "electromagnetic waves interference" into google.

I hope this can be done peacefully...

No. The double slit experiment provides clues for support for both theories... that light/EM "photons" are waves AND/OR particles... are interfering.

I did. I liked the WikiPedia one
http://en.wikipedia.org/wiki/Electromagnetic_radiation

FROM WIKI::: For example, a travelling EM wave incident on a particular arrangement of atoms induces oscillation in the atoms and thus causes them to emit their own EM waves. These emissions interfere with the impinging wave and alter its form.
So... it's probably my fault.

Rephrasing it:
Waves in a vacuum don't interfere with each other.

..........
QUESTION: Where are we going with this?
I don't think that running two bulbs will cause any appreciably interference in the waves/particles of light...

Best to you Joe,
