HID bulb life

[BONGMACHINERY]

hello there i am currently close to finishing my 2nd grow with a conversion MH 400w for veg and an HPS 400w for flowering, and i was wondering how long these bulbs last before i have to change them.... i had to move to south america abd theyre not easy to find here so imn hoping ill be good for a few more grows with these

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.

Generally, 12 months for MH...and 24 months for 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..?
