Lumichrome® 1XX Full Spectrum Fluorescent Bulb - 6500K / 98CRI (Daylight White)

$20 per bulb | Beautiful Fluorescent Light
Please select the correct length and diameter bulb (T8 = 1'' tubes, T12 = 1.5'' tubes).

The Lumichrome® 1XX is our most popular full spectrum fluorescent lamp. With a color rendering index (CRI) of 98 out of 100, and a 6500K color temperature, it provides the closest possible replication of natural sunlight in an artificial light source.

Using Lumiram’s patented phosphor blends, the light of the 1XX is a bright and natural white. If you were to turn on this lamp in a windowed room with natural daylight, you would be hard-pressed to distinguish a difference between the two lights!

We've seen this lamp work equally well in various applications: everywhere from art studios and kitchens to dental labs, offices, and boutique fitness facilities. With such a high CRI rating, you really can't go wrong.

Made in Germany to the highest standards.

Fluorescent tubes are final sale. Please double-check that you have selected the correct length and diameter bulb (T8 = skinnier 1'' diameter tubes, T12 = 1.5'' diameter tubes). If you're unsure, please contact customer service for assistance finding the correct sized tube for your application.

My main concern was breakage during shipping, but they were packaged very well and arrived intact. I just installed them in my studio and their light is slightly blue, as compared to my old GE Ecolux bulbs. Those were 5000K though. I think I'll like these better
