Few start up ????

Hi,

What is the difference between a regular MH bulb and an MH conversion bulb like this ( http://cgi.ebay.com/1-Plantmax-PX-MH250-LU-250W-MH-Conversion-Grow-Bulb-/110569691162?pt=LH_DefaultDomain_0&hash=item19be77981a).

Next, which MH bulb will I need with this unit do i need converion or will a regular work? ( http://cgi.ebay.com/250-WATT-HPS-DIGITAL-GROW-LIGHT-6-AIR-COOLED-TUBE-250W-/370517146202?_trksid=p4340.m263&_trkparms=algo%3DSIC%26its%3DI%252BC%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%26otn%3D10%26pmod%3D160600437815%26ps%3D63%26clkid%3D582999866220389982) it says that it will work with both bulbs.

Next, I am between a 250W system and a 150W system. The 150W system doesn't have much cooling optionts especially if I want to run a carbo filter. The 250W have better cooling options, however how much of a heat difference am I looking at between a 150W and 250W also, If I ran no cooling system will head be an issue and especially the fumes of the garden once bloomed?

I would like to avoid cooling system if possible but if scent and heat will be an issue than i dont have many option :)
