Fluorescent light short life
WebThe three-stage process of excitation, excited lifetime, and emission is called fluorescence. Fluorophores absorb a range of wavelengths of light energy, and also emit a range of wavelengths. Within these ranges are … WebAug 5, 2024 · I've already had 3 fail within 3 years of installation which supposedly had a 20 year life span. One good option is for a typical 4' florescent fixture is to replace with LED tubes that work with the ballast or get tubes that completely removes the ballast and rewires it directly to the tubes.
