Frequently Asked Questions
What does F17T8 mean?
F17T8 is a standard lamp designation. F indicates fluorescent, 17 is the wattage, T indicates tubular shape, and 8 indicates the diameter in eighths of an inch - making this a 1-inch diameter tube. It is a standard 2-foot T8 lamp used across most major fixture manufacturers.
What is the difference between 6500K and 4100K fluorescent lamps?
4100K is cool white, the most common color temperature historically used in offices and retail. 6500K is daylight, producing a brighter, bluer-white light that more closely mimics natural outdoor daylight. 6500K is preferred in environments requiring maximum visual clarity, color accuracy, or where natural light simulation is important.
What is the difference between 6500K and 5000K?
5000K is a neutral daylight used in many commercial and retail environments. 6500K runs slightly cooler and bluer, commonly used in applications such as graphics, print, medical exam areas, and facilities requiring a full-spectrum daylight appearance.
Is this lamp dimmable?
No. The F17T8/SP865 requires a standard non-dimming T8 ballast and is not compatible with dimming ballasts.
