I picked up a new 14k 150 watt metal halide today and plugged it in and
turned it on. The brightness doesn't seem as much as my 10k bulb and it
looks much blue'er then I thought it would be. I heard about burn-in times
for MH Bulbs, so has anyone got some idea how long I should wait for the
burn-in time to elapse?

The bulb I got from www.corallights.com.au

Generally a 14K-20K bulb won't appear as bright as a 10K....

the reason it doesn't appear as bright is that we Humans don't see the full
spectrum of available light, only a portion of it. so the reef lights are
putting out light the corals need, and use, but humans can not see. but its
still there.

as for burn in, the worst of it should be in 48 hours of running, then level
off some what. SO Just have them a few more inches higher for the first few
days, then, each day lower them a but till they are back in the original
place.

You might, but I don't. I can't change the height of them, the hood is a
fixed. I just have to bare with the burn-in time then. As long as the corals
are happy, I can live with the extra brightness from a flouro light.

Typically, 100 hours. 9 or 10 days.
