Hard to figure, how're you're running 1200 watts through only four cobs, I'm only running my CXB 3590 cobs at 50 watts, each of 12 for a total draw of 600 watts. Mine I've got about 6" over the tallest buds and around 12" over the canopy average. At over 6X the power through them, I don't have any clue how far to space your light above the plants. What drivers are you using?
Not so sure I'd want to put the back of my hand under your lights to feel the heat with the distinct possibly of getting blasted...

One question what/how are you controlling the heat production? I know that Timber runs there's at 100 watts per cob with big assed finned heat sinks...

HLG-320H-C1400B is a 320 watt driver. How are they wired? You might want to wire them a differant way and just run the 320 watts with the 4 cxb3590's.
They will be a lot cooler and last a lot longer.

Cbd cob = 18-24 inches ( if you have dimmer) dimm the cob gradually through the cycle by small percentage every few days so the plant can evolved to the level and not get stressed.
