There are a number of factors that are put into consideration when you are selecting the MH bulbs (metal halide bulbs) that you want to use to light up a room or a certain place. First it is important to weigh all your options and see if MH bulbs are the correct choice of bulbs or whether you would be better off using fluorescent bulbs such as the t8 fluorescent bulb or the t5 fluorescent bulb. Making the right choice ensures that you have the maximum quality lighting possible and also that is suitable for your intended purpose. You should also find out the type of halogen transformer that you need to purchase along side with your bulbs. The halogen transformer you buy depends on the wattage of your metal halide bulb.

The first thing to consider is the number of watts you want on your MH bulbs. There is a variety of wattage options to choose from for your metal halide bulbs. This again depends on the intended purpose that the bulb is to serve as well as a variety of other factors. The first factor to consider before selecting the wattage is the size of the room or the area you need to light up with the metal halide bulbs. For big rooms you will need a high wattage MH bulb but for smaller rooms getting bulbs with lower watts is more suitable. If you are using the bulbs to light up an outside area then you also need to consider the area you need to light up. If your porch is very big then you need a higher wattage bulb, however, if you have a small porch or you just need to light up the garage area there is no need of getting very many watts.

Another thing before picking on a particular MH bulb or the t8 fluorescent bulb is to determine its compatibility with your lamp. There are lamps, especially those used in aquariums, which have dual prong base while there are some that are screw in. For the screw in lamps there are different base measurements which differ from lamp to lamp. Therefore before picking a particular bulb you have to find out whether it is compatible with your lamp base. You should check the code and labels on the bulb and the ballast so as to ensure that they match exactly.

You should also consider the size of the bulb so that you know that it will fit where you intend to put it before you buy it. It is also good to check that the MH bulb is in the color you want in. These bulbs come in a variety of colors such as blue, red and green, although if you are buying colored ones then you have to consider the wattage again. It is also important to check the brand since some brands are superior to others. If you do not know which brands are superior you can consult experts or read reviews so that you know which bulbs are superior. You can also decide to get photocontrols with you bulbs in case you are using them for out door lighting so that they come on and off automatically.
