Obsolete T12?

This question is from 4 ft. T12 40-Watt Cool White Supreme ALTO Linear Fluorescent Light Bulb (30 per Case)

I've bought two cases of these at my local Home Depot in the past two weeks. The packaging looked new. I thought the DOE mandated an end to manufacturing new T12 fluorescent bulbs several years ago as a part of the same rule that ended the 60Watt incandescent. Did they delay implementation of the rule? How much longer does Home Depot expect to be able to get these tubes?

Answer: 
The ruling for lamp efficiency has been in place since July 2012. The lamps that you purchased are exempt from DOE ruling and not impacted by legislation. That’s why we can continue to make and sell the lamps. Thank you.

Rated 5.0 out of 5.0 by BEST PRICE EVER CHECK ONLINE FOR THE CHEAPEST PRICE AROUND AND YOUR STORE WAS IT!! SHIPPING WAS FREE AND QUICK!! May 17, 2016
Rated 1.0 out of 5.0 by We received a box of dust. We received a box of dust, every bulb was broken. We returned to our local Home Depot in Homer Glen and they issued a refund and said they would re-ship the bulbs since they were not in stock. We have never received the replacement bulbs. We went to Menards and bought bulbs a few days ago. May 4, 2016
Rated 5.0 out of 5.0 by Super Value All of the bulbs work great. They arrived in perfect condition. January 26, 2016
Rated 2.0 out of 5.0 by Will review replacement lighting as these are not bright enough for me. Unfortunately, I must return these bulbs as they are not bright enough for my art studio. The Philips bulbs I originally had in my studio, most of which are still working after 11 years, are F40T 12/DX Alto collection. Was unable to find these and could not find information indicating which are "bright, brighter and brightest" for those of us unfamiliar with lighting lingo. The nearest Home Depot is 40 miles away so will have to check another day. Was very pleased with the original ones and would like to replace this order with comparable lighting. What do you suggest?

Rated 5.0 out of 5.0 by Great bulk price, super bright I love buying the bundle pack to save money. This makes it just as ap as buying it at the big box stores. July 21, 2015
Rated 3.0 out of 5.0 by Philips4 ft. T12 40-Watt Cool White Supreme (4100K) ALTO Linear Fluorescent Light Bulb Not bright enough compared to the Alto 5,000K bulbs. Got these instead because the 5,000K were much more expensive at Home Depot.Should have purchased the 5,000K at a lighting store where they have them for the same price as Home Depot's Cool White bulbs, namely $60 for the case...
