Anyone made their own LED lamp?

Good idea. Amazon really restricts the Kindle scene - I don't have much hope. Our publisher C.U.P., is creating a live, always-up-to-date html-5 web version that could fix some of these issues. We're eager to see how that works out.

On the second page right below where it says Third Edition 2015. If there's no printing number, then you have the first printing.

Maybe the first printing will be worth more some day like it is with Tom Sawyer.

I just bought the book from Amazon a couple of weeks ago. No printing number and all the errors on your errata list. :-(

Yes, we manufacture and sell LED lamps. The trick to LED lighting is that it exploits the high intensity light to produce the same effect as a high wattage CCFL lamp. In our experience,

5 5-Watt white light LED lamps provide the same intensity as 2 - 3 30 Watt CCFL lamps. The power Each of our lamp types are powered by a small built-in reactive power supply. For really high intensity lamps, we use small built-in SMPSs or linear power units. power supply

I suppose new designs could use LEDs and a piece of glass rod as a light pipe.

Sounds like a really expensive solution to a really simple, long solved, problem.

Yep. A solution in search of a problem.

Was it "Ships from and sold by Amazon.com." or was it one of the other cheaper sellers?

Sure, but outlawing incandescent lamps wasn't my idea.

Try to replace the socket in the device where it's in with a standard bulb socket. Should that fail I'd crack open the base of the failed lamp and make an adapter from that so that you can then fit off-the-shelf LED flood light lamps and such.

I did something similar with a fixture we brought from Germany. It's above our smaller dining table in the kitchen and we just fitted LED bulbs in there. Using adapters, except we were able to buy those. They make the bulbs sit a smidgen higher but that doesn't bother us.

As one who never rushes to a solution, I'm just going to buy some lamp "fitters", a bowl-shaped glass shade, and change it to a 3X E26 socket arrangement, and outfit it with those new GE stik lights...

I like my office _bright_ ;-) ...Jim Thompson

I love to cook with wine.     Sometimes I even put it in the food.

"light pipes" which are not simple polycarbonate injection moldings are typically a bundle of optical fibers fused together as a rod. "Optically correct light pipes" will transfer an image from one end to the other and are a fused bundle of 'indexed' fibers and have polished faces. They typically also have a half twist in them to provide image erection (no not a hard on).

Oven bulbs haven't been outlawed. At least in the US.

For this application, they haven't been.

Ships from and sold by Amazon.com. I received it on Jan 30.

I just bought three to give to employees. I guess I'll order a couple more.

Oh, I'm sorry to hear that. Who knows what's in Amazon's various warehouses. If you like, I'll trade it with you for a 5th or 6th printing. I'm giving some to relatives, friends, etc., who wouldn't care about the printing number.

High power LEDs don't mind 140 C. That's easily manageable by putting them behind an IR reflecting window and giving their heatsink some outside air.

Standard oven bulbs will melt during the cleaning cycle unless they're inside their protective dome. Little quartz bulbs can handle the cleaning cycle but they cost more than an LED.
