Review on Panasonic FDS18E35 Fluorescent 🔆 Bulbs Replacement: High-Quality and Reliable by Seth Waldron

Whilst I don't know the lifespan of these bulbs, they have just been installed I expect them to last as long as the brand they replaced. They lasted 15 years in a fan bath. Fluorescent lights usually turn off immediately or last for a reasonable time. Hooking it up was easier than upgrading to an LED, which required bypassing the ballast.
