EISA 2007: Incandescent and Fluorescent Timeline

New DOE Fluorescent Standards

Summary of Lamps Affected by 2012 DOE Standards New standards are based on EFFICACY – higher lumens per watt and higher CRI ratings T12s Majority of 4’ lamps fail All U-Bents fail 110W 8’ HO lamps fail T8 700 Series Fail T5 All pass

How many T12 & T8 Fluorescent sockets are there in North America?

Linear Fluorescents in each Segment

Switch from 34W T12 System to 32W T8 System

Lumen Maintenance T5 T8 T12

Key Points T12s are everywhere The further they are from a metro area the less they’ll be sought out for upgrades You can make the difference And while you’re at it: Every old-technology metal halide high-bay light in your service area could be replaced by T5 or T8 fluorescent fixtures and save 40-60% power Upgrading one 400W metal halide fixture can do as much as upgrading 5 or 6 4-lamp T12 troffers
