As 1800ES points out, light output can vary a lot in non-incandescent lamps (although I've also noticed dimming in those bulbs right before they stop working). I wonder if he's referring to CFLs and their habit of going from lower to higher output after they're switched on?

I agree with you about the dimmable light, Ann. And it looks like it stands a good chance of winning this round of Gadget Feeak voting. We'll know in a few days when we shift to the fifth round.  If Andy wins with his dimmable lamp, that will be two for him, since he won the first round.

Thank you for the clarification on that, armorris. I think you are probably right in that there is not another dimmable LED lamp out there, and it's a great invention. Good luck to you!

Ya, the devices that provide light these days are so varied, dimmers should be on all of them.  You can't just grab a 75 watt bulb and know what you'll get.  Next, let's work on a uniform and easily located volume control ...... the old knob was NICE!

I voted for the dimmable LED desk lamp. I think dimming should be available on every light fixture, and there aren't nearly enough of them.

ElizabethM,

My LED desk lamp is both practical and functional. I built 4 of them, which I use everyday. The dimming greatly enhances the utility of the lamps. I know of no commercially available LED desk lamps that are dimmable.

Good point, Andy,

It's easy to find these projects in their full presentation. On the home page, look at the Gadget Freak posting and you'll see the word "all" at the top. Click this will get you to the full list of complete Gadgewt Freaks.

I am with you, Chuck. That seems the most impressive to me. The others are quite cool, but more hobby-type gadgets, whereas this one is not only clever but as you say, practical, and functional.

Build instructions

I hope the readers know that complete build instructions and parts lists are available elsewhere online. Obviously, the regulars will know that. I believe that how easy a gadget is to build might play a role in how attractive a particular project is.

You pretty much described my thinking on the selection, Chuck. The hydraulic force indicator is a very clever gadget.
