Innovation or e-waste? Apple rumored to ditch headphone jack

Could and did. An early Shelby Electric (Chaillet) bulb still burns in a firehouse in Livermore. It has been in continuous operation for 114 years. The thing is, the bulb is also relatively dim compared with modern bulbs.

One big reason light bulbs burn out so quickly is that the filaments are thin. They're thin because thinner filaments burn hotter (less surface area to dissipate power), and thus dissipate more of their power as visible light rather than as heat.

Additionally, that 114-year-old bulb is apparently dissipating much less power than it should. Nobody has studied it carefully enough to determine why this is the case, but apparently it has higher than expected resistance when at normal operating temperature. If I ran a current-generation 110 volt light bulb at 7 volts, it would last nearly forever, too.

Careful there. LEDs themselves do last almost indefinitely unless you abuse them. That doesn't necessarily mean that the circuitry needed to drop the voltage down to ~3.5VDC will last forever.

We must get a better range, just at the local supermarket you can get bayonet, screw (Edison 14 & 17) & GU10 (In a full range of shapes & colours, if you count white as a full range ).
You can get halogen type replacements easily enough online.

What kind of fitting does your lamp have?

For the recessed lighting in my house I am using Phillips 800060 65W Daylight.

I replaced all of the overhead case light Halogens in my store with MR16 Daylight LEDs. The savings in cooling costs were more than the savings from lower voltages. Halogens put out a lot of heat.

I looked at the first link and it doesn't look like a light bulb, it looks like the housing for a light bulb.

It's a complete unit, the LED is integrated.*

In the one room where I have recessed lighting, I use LED BR30 replacement flood bulbs.

*I'm probably going to get similarly integrated fixtures to replace my workshop florescent tubes, and my kitchen ceiling fixture. No particular reason for buying separate fixtures and bulbs if the bulbs should never need replacing, especially if the integrated ones look nice and...um...integrated.

I just don't trust that they will never need replacing. The CFL bulbs I put in the kitchen all died within six months, and a few died after one to two months. Regular bulbs last a few years.

I'd be cautious about assuming that LED bulbs will never need replacing. While the actual LEDs themselves are very robust, I've had a few failures of the associated circuitry. Still much better than incandescents, but not a zero failure rate.

You may notice I said "should" and that I mentioned this concern myself a few pages ago.

In the case of these fixtures, the hope is that they're even better made than the cheaper bulbs, and they certainly have more room to include proper heat-sinks, etc, and if they do fail, well, they are not that much more expensive than the bulbs anyway, and you're paying for the nice styling and integrated look, and man, this is about the longest sentence I've written in a while!

I use basically the same thing in my can/pot lights in my kitchen and bedroom/master bath. I bought them at Home Depot. I LOVE them!! They provide a very nice light! But, I hate CFLs, so maybe I'm biased!!

Have you tried "daylight spectrum" CFLs? I think they're great - a much more natural-looking light than the normal ones.

I think I only have 4 fixtures left in my house that don't use LED bulbs of some sort. When the CFLs in those die they will be changed to LED too. As crazy as it sounds, CFLs really bother my eyes. I get frequent headaches when I am around them. Not just the tube fluorescent, but the compact fluorescent bulbs too. But, my eyes are very very sensitive, or maybe I'm just a whiny butt!!

So after all that I wrote above, my wife went to get a new phone today, and even the 'subsidised' price for any phone she wanted was so high, we decided to switch to the new device payment plan. We spent a lot of time in the shop and honestly I'm still not sure if I'm getting a better deal or not. More importantly, to the topic of the thread,the new Samsung phone she wanted no longer has an as slot. We're both ticked off at that. It was a very Apple thing to do, and if we thought anyone at Samsung cared, we'd be complaining.

There are engineering benefits to foregoing the slot. It's not entirely about shafting the customer.

Indeed, but I think customer benefit should dramaticly outweigh them if not for the shafting.
The kind of data that most folks use on a smartphone--hires photos, videos, music--is big, and needs space.
It can be argued that Amazon figures most users will never fill the 2 or 4 gb on an eink kindle so the slot would only serve a small segement of users, but smartphone makers know darn well smartphone uses will need More and more space, and they want you to pay through the nose...one way or the other...for it. Grr!

@ApK: if an SD card slot was important to you, you should have waited until the new S7 comes out. It will (should) be announced next week, being available sometime march. Supposedly the SD card slot will be back.
