IEA 4E SSL Annex finds LED retrofit lamps cut environmental impact by 44 to 61% compared to T5 and T8 fluorescent lamps - 4E Energy Efficient End-use Equipment

Preliminary findings from the IEA 4E SSL Annex show that environmental impact for T5 lamps can be reduced by 44% and for T8 lamps by 61% if they are replaced by LED retrofit tubes. These are LED “plug-and-play” retrofit tubes that can be installed directly into existing fluorescent fixtures. As the 147 countries who are […]

@janrosenow Yes, but they have a high failure rate, and I know others who have had failed LED replacement tubes. I'm considering replacing these with ultra efficient bulbs because they use half as much power.

@johnweyman manufactures' decision to package LEDs and cheap power supply units into a non-repairable product causes the problem in a large part. Diode failures are rare, getting hundreds of them to fail is very unlikely. Buy LED strips and a reliable power supply, and consider lighting a solved problem
