CNN story here. They stated that some high efficiency incandescents will remain, and these bulbs have a filament that's "wrapped in gas." That's an odd way to describe a halogen.
It's technically not an incandescent bulb ban because halogens will be available for a while. The real incandescent ban doesn't start until 2020 when the minimum efficiency mandate for all general lighting of 45 lm/W kicks in. And that's assuming the so-called 2X/3X/4X bulbs can't meet that guideline. I have a gut feeling we'll be able to pass 45 lm/W and then some with IRC. What's disappearing are cheap incandescents but frankly those are penny-wise and dollar foolish. You pay less upfront only to pay a lot more down the road in terms of energy costs.I would actually be transitioning to LED's faster, and thereby reducing my energy consumption faster, had the idiots who passed the incandescent bulb ban simply refrained from acting.
Fluorescent and other discharge lighting already has lifetimes within the same order of magnitude as LEDs and this hasn't seemed to hurt companies. It's all about margin. A company may make once cent profit on a 25 cent incandescent which lasts for 750 hours. To make a similar margin per unit of time on an LED bulb which lasts 75,000 hours they need to make $1 per bulb. They can certainly do that and still keep the price of LED bulbs within reason. Competition will keep costs down also. I highly doubt we'll see an LED monopoly given that every major country has poured heavy R&D into LED development. You may be left with a handful of manufacturers who make bare LEDs, but there will be a lot more competition putting them into finished products.First they banned the incandescent, so I bought florescents. Then, they banned the T12 linear bulbs and ballasts. Next, comes all florescents because of the mercury. What we will be left with is l.e.d.s.. If they are good bulbs and last, the companies will get to market saturation quickly and start to decline because no one needs their products for another couple decades. If the bulbs burn out quickly, no one will buy them and I could see the technology going away from too many people being turned off. What I think might happen in the future is that the l.e.d. bulb companies will put out small incremental improvements in efficiency to bring in more customers while the government will keep pushing them to make more efficient products quicker by banning the less efficient products. If the government goes too fast with it's mandates, the companies won't cover the costs of R & D by selling the older product and it will bankrupt them. If the companies have absolutely no efficiency mandates forced on them, they will naturally improve the efficiencies at a sustainable rate to keep up with the competition. What we'll have to worry about is that if the pressures of competition and government regulation bankrupt many of the companies, we could potentially end up with a monopoly on lighting devices stiffling efficiency improvements and increasing costs. Hopefully this all turns out o.k. for us and we get decent bulbs at a decent price. This would be a great time for Philips to start selling that 200 lumen/watt bulb they've been bragging about.

Incidentally, companies already know the LED bulb replacement business will reach saturation soon, and then actually start to die as people get wise to replacing their A19 fixtures with purpose-built LED fixtures. Such fixtures will probably eventually be mandated in new construction. We'll end up with much the same situation as we have with linear fluorescents. Most of the money is made on the fixture, not the replacement lamps. In the case of LED fixtures, there won't be much need for replacement lamps as they could potentially last as long as the structure they're in. That being the case, the business model will change to ensure a company remains viable just on the profits from selling fixtures. New features such as variable CCT and remote control are what will probably get people to buy into LED fixtures. Off-topic but a similar business model will exist for electric cars. Manufacturers can no longer heavily depend upon the income stream from repair parts, so they'll aim to make more upfront on the initial sale. They could do this by either charging a higher price, or charging the same price as ICE vehicles, but manufacturing the EVs for less. Because EVs are inherently much simpler than ICE vehicles, I suspect the latter approach will dominate. We may see something in between for LED fixtures. They'll certainly cost more than incandescent fixtures, and perhaps a bit more than fluorescent fixtures. The extra features and virtually unlimited lifespan will justify the extra price.
We are close to that now. The companies that make their own high efficiency LEDs have an advantage - no middleman when sourcing LEDs. Philips and soon Cree will dominate the market.What we'll have to worry about is that if the pressures of competition and government regulation bankrupt many of the companies, we could potentially end up with a monopoly on lighting devices stiffling efficiency improvements and increasing costs.
We are only getting 200 lumens per watt LEDs in the lab, not production. Add in driver and optical losses and my guess is 140 lumens per watt at the bulb level. I would not take over-enthusiastic marketing speak at face value. They may be another '$60 bulb'. (An AP article with the title 'Would you buy a $60 light bulb' was reprinted by newspapers worldwide during the launch of the L-Prize bulb. Notice the L-Prize bulb, still the best at ?96 lumens is no longer in production. Too expensive without subsidies.)This would be a great time for Philips to start selling that 200 lumen/watt bulb they've been bragging about.
Soldering LED bulbs into screw-base fixtures is just silly. To comply with this mandate it makes more sense to install purpose-built LED fixtures instead of either plug-in or screw-base fixtures. Yes, in the case of LED fixtures the LEDs will most like be permanently soldering in place. However, that shouldn't matter because a properly designed fixture will last the life of the structure it's in without needing to replace the LEDs. The driver should be removable in case it needs replacing, but in general the LEDs themselves are the most robust part of any LED lighting system.In California, the change from screw in to plug in fixtures has already been mandated in new construction. In fact, to comply with laws for new construction, l.e.d. bulbs that are screw in have to be hardwired/soldered into the fixture to prevent the owner from using incandescent bulbs (voiding the warranty and making replacement difficult). Most of the good new l.e.d. bulbs are screw in. The plug-in bulbs are mostly florescent and much more expensive compared to screw in florescents that you can get for about a buck. I don't mind inefficient lighting being banned if there is a cheap better alternative. However, I do have a problem with having to change out the entire fixture and bulb if I ever have to replace a hardwired l.e.d. because some bureaucrat won't let me screw in my own lightbulbs.
Higher efficiency and lower price aren't mutually exclusive goals. As you increase efficiency, you radically reduce the need for expensive heatsinking or other measures to keep LED temperatures within limits. To give you some idea of the rough numbers involved, if you have a 100 watt replacement lamp (1600 lumens), then the approximate numbers for waste heat at various efficiency levels are as follows (all cases assume the efficacy of the emitted light is 300 lm/W):We are only getting 200 lumens per watt LEDs in the lab, not production. Add in driver and optical losses and my guess is 140 lumens per watt at the bulb level. I would not take over-enthusiastic marketing speak at face value. They may be another '$60 bulb'.

If you are willing to pay $60 for a 200 lumens per watt bulb let Philips know. Otherwise they will concentrate their efforts at getting the price point below $10.

Trying to wrap my head around this and failing. Dimmers make incandescents markedly less efficient and dim - dim to the point that the typical installation with dimmed incans has quite a few more sockets than otherwise needed to account for this reduction in output. The vast majority of residential occupancy sensors and motion sensors seem to depend on trickle currents through the bulb itself, thus are incompatible with anything other than incandescents.Edison sockets can still be used in other locations. But Title 24 mandates that they be on a dimmer (95% max) or a vacancy sensor. For outdoor lights, they must be on a motion sensor.
Heck, even "better" alternative would be nice.
It seems that there are very few available light sources that approach the color rendering of an incandescent; choices narrow even more if you don't want to use can lights.
There are inexpensive LED "bulbs" on the market, but high CRI versions seem to either pop up and disappear (e.g. L-prize) or be available only in limited markets (Cree True White, unless you mail order) or else be expensive and hard to find. The mass market stuff (e.g. regular Cree) is "OK" but still a little disappointing to those of us who grew up surrounded by only incandescents.
I'm disregarding CFLs as they never were really that nice to begin with; I just don't like them, although I have grudgingly used them. Which is odd as I have been able to buy linear fluorescent tubes that are rather good.
