Unlike LED lamps, most fluorescent lights and CFLs harbour hazardous materials, such as mercury. This requires their careful and proper disposal, ensuring that they do not contaminate landfill sites .
As most cannot be dimmed, Fluorescent lights may suffer from flickering. Unfortunately, people can be sensitive to this effect - resulting in eye-strain, migraines and other head-aches. LLED lamps utilise solid-state technology enabling stable dimming with no flickering.
Fluorescent lights may take noticeable time to reach optimum brightness, a problem that is compounded in cold conditions. LED lights are instant-on in any environment – even inside cold rooms and freezers.
