Frequently Asked Questions
QWhat does 5000K mean for LED tubes?
5000K refers to the color temperature of 5000 Kelvin — producing daylight white light. It is the preferred CCT for warehouses, industrial facilities, and parking structures where maximum visual acuity and alertness are required. Cornea Lighting offers 5000K in 18W (IP20 and IP65) and 36W 8ft formats.
QIs 5000K too bright for offices?
5000K can feel harsh and clinical in office environments. For offices, 4000K neutral white is generally preferred as it provides adequate illuminance without the harsh feel of 5000K. 5000K is best suited for warehouses, industrial facilities, and parking structures.
QWhat is the difference between 5000K IP20 and IP65 LED tubes?
The 18W 5000K IP20 tube is for dry indoor locations (warehouses, offices). The 18W 5000K IP65 tube is rated for wet locations — fully dust-tight and protected against water jets. IP65 is required for food processing facilities, car washes, outdoor covered areas, and any wet industrial environment.
QIs there an 8ft 5000K LED tube?
Yes. Cornea Lighting's 8ft T8 LED tube (CL-T8-8F-36W-50-B) is rated at 36W, 4,600lm, 5000K daylight. It is DLC QPL listed and UL certified, designed for high-bay warehouse and industrial applications.
