Keep in mind that with age and usage, all 5000 K fluorescent lamps tend to shift in their color balance and their light output decreases. In order to get the best results on your viewing surface, exchange the bulbs after 2500 hours of use. Check your JUST Normlicht hour meter which displays the total number of hours the lamps have been used to know when to order your new replacement tubes.

And think about this:  Save money on shipping and other charges by ordering complete cases from us!
