hurricane and vortex fans will prob last a lifetime too .. they come w/ a 5 yr. residental or industrial use warranty . 24 hrs. a day for 5 yrs straight , if they fail they will fix or replace at their discretion . but w/ a cooltube you can run your 400w lights w/ in inches of your plants w/o harm .
