    Wetty,

    Yes , you could use the normal halogen floodlights instead of MH.
    However the halogen bulb outputs are normally in the range of 4000 - 6000 K, which means the light will be pretty "yellow" in colour.
    As with MH's you will need to watch the heat generation aspect closely.

    Wetty,

    Sorry, I didn't answer your question fully.

    You can use the Floodlight pendant/enclosure for MH as well.

    If you are however going to use MH bulbs , you need to buy a ballast suitable for MH.

    MH's are high intensity discharge lamps and require a special ballast for starting purposes and to control the output voltage .

    Hope this helps

    Oh ... one more thing I forgot to mention.

    If you are going to use a normal halogen floodlight enclosure , you need to ensure that the MH bulb you are buying has a UV shield on it.
    Normally single ended MH bulbs have a UV shield on the one side , but for double ended MH bulb's you need to have a separate UV shield. This UV "shield" is normally fitted into the glass on the front of the lamp enclosure, or you can buy a glass cover with the UV shield incorporated into it.
    Hope this makes sense to you.:p

    Oops ... thought that I might be giving you an information overload .:p

    Basically you can use the floodlight casing that you buy from any hardware etc. to house the MH bulb. You need to buy a MH ballast though to drive the MH bulb.

    MH bulbs come in two forms : Single ended and double ended (similar to the halogen bulbs)

    Most standard halogen floodlight casings accept only double ended bulbs , so if you're fitting a MH bulb you need to make sure that the glass cover on the floodlight casing has a UV shield built in. The glass cover is available for separate purchase.

    My honest opinion though is that it may work out much easier to just buy the MH pendant/casing and then buy the ballast separately if you so desire.

    Depending on the wattage you are looking for a 70/150W MH casing & ballast will work out to be approx R 450-R500. The bulb will however set you back approx R300.

    Hope this doesn't create more confusion ?
