remember, they can always ship the bulb to the location you are now.
it's always a good idea to have a back up set of bulbs. well , i guess you do have a replacement if one breaks, hey! |

about 18-24 months of 24/7 use depending on wether it's MH/HPS.

dont hid lights lose somethin liek 30-40% of their lumens output in their lifetime..? so maybe you can replace your bulb when theyre not so efficient anymore..?
