60 lumens per watt for lamps > 40 watts, 50 lumens per watt for lamps > 15 watts and ≤ 40 watts, and; 40 lumens per watt for lamps < 15 watts; There are 14 states that have adopted the 2009 IECC, six have an effective date set for late 2010 early 2011. Within the next three years, approximately 33 states will have adopted and implemented IECC ...
As of 2011, some LED bulbs provide up to 150 lm/W and even inexpensive low-end models typically exceed 50 lm/W, so that a 6-watt LED could achieve the same results as a standard 40-watt incandescent bulb. The lower heat output of LEDs also reduces demand on air conditioning systems.
The Canadian federal government banned the import and sale of 75- and 100-watt incandescent bulbs, effective 1 January 2014. On 1 January 2015, 40- and 60-watt bulbs were also banned, although there are exceptions for oven lights, decorative lamps (light bulbs), appliance bulbs, 3-way fixtures, chandeliers and rough service/utility bulbs.

Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.The distinction between efficacy and efficiency is not always carefully maintained in published sources, so it is not uncommon to see "efficiencies" expressed in lumens per watt, or "efficacies" expressed as a percentage.
