Review on Panasonic FDS18E35 Fluorescent 🔆 Bulbs Replacement: High-Quality and Reliable by Isaiah Edgar

3500K - Fairly cool white light, not really "daylight" but works great in my (indoor) hallway. I have been using new lamps for 2.5 months. They "turn on quickly" when I flip the switch and give off a constant light. No flicker. I'm happy with them. But next time I'll order a warmer bulb for my inner hallway.
