To clarify - the LED lamp replacement program being incentivized by Oregon is to replace sodium lamps with LEDs of the *same* efficiency, but that use less power. What this means is lighting that is about 30-50% dimmer. 

We'd save even more power by just eliminating street lights altogether if we're going to resort to spending tax dollars on lighting that fails to meet street lighting standards (which are not in place for parking lots, which I believe was the original intent of the incentive) from Oregon Department of Transport http://www.oregon.gov/ODOT/HWY/TRAFFIC-ROADWAY/docs/pdf/Traffic_Lighting_Design_Manual.pdf . 

If this is the case, it's conceivable that all substandard LED street lighting, as would be the case with dimmer streetlamps, may require replacement, unlike parking lot lamps which appear to be the intended recipients. Yikes - pay for it twice, Eugene, and no rebates/credits?

Heads need to roll if this all proves to be true...and that's the job of a "free" press.
