as long as they are the same dimensions i see no issues. there actually was an issue a year or so ago where 1000k hps DEs were slightly different lengths

Suitable for use in any DE hood with any 315W CMH ballast.

sounds like thats your answer. the vertical 315 reflectors are equally as good and also air coolable

seems ok but not ridiculous.
you can buy a programmable solistek with built in timer for $200
Yeh, I was looking at those but they are 130 dollars extra and maybe 20 bucks shipping, plus some amazon reviews say the timer is crap
