Let's take a simple light bulb and make it more complicated and more effort to change.

Or just buy a regular compact fluorescent and replace it every 6 years.]]>Jul 3rd 2008 7:31PMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/Jul 3rd 2008 7:49PMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/
I've seen people dump car batteries in a garbage can. The tiny amount of mercury in fluorescents doesn't even register.

Assuming that people know there's mercury in there to begin with and that it happens to be extremely toxic.]]>Jul 3rd 2008 7:58PMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/]]>Jul 4th 2008 2:50AMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/Jul 3rd 2008 7:49PMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/
Why Hitachi is marketing it as a revolution or their own invention is anyone's guess. I guess they think nobody will notice. I hope they use a standard fitting and voltage or else you'll just lock yourself into (or out of) a single bulb forever.

At $0.15 per kWh, $13 is 87kWh. It takes 1850h or 77days to use up 87kWh at a 47W load.

So, this bulb will pay for itself in 77 days of usage. If its on 8 hours a day, it will pay for itself in 7-8 months. I'd say thats a good investment. It starts paying for itself before its one-fifth through its life. It'll save you like $65 before it goes out.]]>Jul 3rd 2008 10:29PMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/You forgot to add tose details in your calculation.

Incidentally, it has more tricks up its sleeve:
The company reportedly improved the composition of filler gas in the arc tube so that the lamp becomes bright immediately after it is turned on. But, because the new composition has poor resistance to heat, the company adopted proprietary heat dissipation measures.

We'll just use up less Oil every year, and the world will live for a year or two longer before WW3 emerges xD]]>Jul 4th 2008 7:04AMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/What I think is the problem though is that to make the bulb detachable you need to make the already large base even larger, and I think that's not practical and even almost impossible in 80% of the cases.

I can buy 2-3 normal fluorescent bulbs for $14 so the replacements
had better be cheap!]]>Jul 4th 2008 5:47AMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/
Sounds like a ballast and a seperate CFL? I used these kind of lamps with seperate ballast at least 15 years ago. Because it was cheaper at this time. I stopped doing this when it was cheaper to buy CFL bulbs with integrated ballast.

Maybe there is something else new about this?]]>Jul 4th 2008 8:20AMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/Jul 4th 2008 11:32AMhttp://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/http://www.engadget.com/2008/07/03/hitachi-and-seiyu-develop-light-bulb-with-replaceable-arc-tube/]]>Jul 4th 2008 1:09PM
