Changes

Invented by A.E. Becquerel of France in 1857, today’s fluorescents are available in full spectrum types with quiet electronic ballasts replacing noisy magnetic ones [5]. Cycling rates have been increased to reduce flicker. Because of the mercury, be careful not to break fluorescents, and dispose of them in an environmentally safe way. The USA Environmental Protection Agency publishes guidelines on what to do if a bulb breaks [57]. Also, don’t use fluorescents in places where you would be at risk if a tube broke. Use LEDs instead.

Cold cathode fluorescents (CCF) are similar in construction to neon tubes and have up to 25,000 hours of service life. They are readily dimmable. Look for models that are listed for marine, RV UL, CSA and CE (Europe), and meet the Ignition Proof test requirements of the United States Coast Guard, as stated in Title 33 CFR 183.410. CCFs are more efficient than other fluorescents but the tri-phosphor fluorescents have the most pleasing colour.
