ORBIK EXPERT TIP : Do lamps need maintenance? Yes, every time you change a lamp counts as maintenance. If you own the outdated tubular lamps, maintenance of this is going to the hardware store and a journey up the stepladders to buy, find and fit every 8,000 hours. LED tube lamps lasts up to 25,000 hours depends on your usage but if you only use 4 hours a day, this lamp could last up to 18 years!
