...they didn't actually ban them. They just set efficiency requirements.
Is this really the case? I ask because lumen measurements are highly subjective. Could the manufacturers simply revise their measurement system so that the measurements read high enough to satisfy the law, without actually changing their bubls any?
I'm not sure if they could just revise the measurements. I haven't hit the section of law (if there is one) that gives a government qualified rating method.
However, here's summary of efficiency requirements for anybody interested:
On 1/1/2012: 72 watt bulbs must produce 1490 - 2600 lumens.
On 1/1/2013: 53 watt bulbs must produce 1050 - 1489 lumens.
On 1/1/2014: 43 watt bulbs must produce 750 - 1049 lumens. Also, 29 watt bulbs must prouduce 310 - 749 lumens.
As far as this being the death of halogens: I looked up the lumen output on the 50W bulbs I just bought the other week and they rate at 550 lumens. That's just shy of half what they'd have to kick out come 01/01/2013, so unless I'm buying crappy halogens (Sylvania, cost $8 a pop) I'd say they're right out too.
