What's the deal with 'conversion bulbs', any disadvantages?

Thanks much.
You don't really need a glass divider, most reflectors don't have them and the ones that do, tend to be air cooled. Yes, drops of water on bulbs can make them go *pop* - don't spray water at your bulb

White or chrome? Given the choice white - chrome scratches easily and causes 'hot spots'. Ideally what you want is 'hammered' or 'dimpled' aluminum which spreads light evenly and doesn't cause 'hot spots'.

Conversion bulbs = expensive and lower lumen outputs, but does allow you to use MH output in a HPS system. Even better - get a switchable ballast !
