That agreement is tucked inside the massive 1,200-page spending bill that funds the government through the rest of this fiscal year, and which both houses of Congress will vote on Friday. Mr. Obama is expected to sign the bill, which heads off a looming government shutdown.

Congressional Republicans dropped almost all of the policy restrictions they tried to attach to the bill, but won inclusion of the light bulb provision, which prevents the Obama administration from carrying through a 2007 law that would have set energy efficiency standards that effectively made the traditional light bulb obsolete.

Stopping the bulb ban was a chief GOP priority coming into this year, with all of the candidates seeking to become chairman of the House Energy and Commerce Committee saying they would push through a repeal. That bill cleared the House but Democrats blocked its consideration in the Senate.
