I bought a USB-powered LED-based light with a flexible housing about five years ago, from the pound shop, and it stills works well.
I have not tried to modify it to work with an iPad / Kindle / other connector, so I've no idea whether the circuitry would supply sufficient power, but, at £25, this seems remarkably expensive.
I paid about £3 for my clip-on light off eBay. It uses a couple of button cells rather than triple-As, but £22 gets you a lot of button cells!
mine was £1.50
although it's host powered, but as my eReader has a usb socket on the top edge, that's no problem.
Not sure why you'd buy something this hefty and pricey. Especially as I thought a lot of Kindle cases come with lights built in?
$25 USD, not pounds
At least in the U.S., it sells for $25. My wife and I each have one, they work quite well and are nicely bright (emergency flashlight, etc.). Rechargeable AAA's help with the battery cost.
Paris, she'll suck your batteries dry
$25 is ridiculous and it uses 3 AAA's, so direct driven LED and possibly no dropping resistor, plus the weight of 3 AAA's.
There is a chip that will drive a LED from an input source of 0.9V to 6V. When the source is above 0.9V it maintains a constant light so unlike the 3 AAA direct driven lights, it won't dim as the batteries wear. Below 0.9V, it starts to dim. It sucks every last bit of energy out of a battery.
It costs 80 cents and it comes with an inductor. I'm sure it'll be cheaper in bulk.
I have a LED torch that cost me $11. It uses such a similar chip but it has a hard anodised aluminum body to justify the cost and uses a single AAA battery. I haven't changed the battery in it for months. Attached to pivoting head on a goose neck with a clip, all purchased at a shit shop (dollar or pound stores in your local lingo), total cost $12.
Surely someone can make something better than this.
