I'd like a LED desklamp (white light), but I don't know what to look for, nor where to find them.
I see them online from Hong Kong (ledshoppe.com), and a few at amazon.com. People complain that some just don't output enough light to be useful. Do I need to get one with atleast X led bulbs in it or what do I look for?
And where are they locally? Would like to find some in vancouver or even canada online somewhere, but I haven't found a good selection. Any pointers?

LED lamps arent that useful...
I have a 1 watt LED light bulb, and the light output is very minimal.
Try getting a regular desk lamp and using one of those low powered 5watt CFL bulbs. Thats what i do...

careful with CFL desktop lights though
you're best to test it first
last thing you want is your light source flickering while you work

That's my concern. I have LED christmas lights, and even if I put all of them together in a clump, they don't provide much light. But, are all LEDs the same?

This cheap looking one claims to have 30 LEDs, and be really bright at its high setting, or only use 10 LEDs at its low setting. But I don't know how to figure out if that is marketting or if there are LED lamps that provide really good lighting.

That one is expensive. 66 Leds. But, does that increase total light, or just make more and more dim light along a long bar? I need a consumer reports type of test of these things. LEDs last forever, and my halogen desklamps just run hot and burn out, so I wish there was a good LED answer.

LED desklights are not all that energy efficient.
If you are plugging them into the wall and are of "reading quality" they have to do an AC to DC conversion. AC LED's like christmas lights are totally unsuitable for reading. DC powered LED's lose most of their power in the "brick" which even at low wattage tends to get quite hot.

I wish the technology to put LEDs into regular bulbs become mainstream soon... when it's sold @ CT/Home Depot I might get a few for desk use. (not that decorative colour-changin one :) )

it works great.
I got a $7.99 clip on desk lamp from CT. Clips right to the edge of your desk, or stands up by itself.
I bought a bulb from Home depot for $2.99 with the Ontario energy saving rebate it came up to be $2.xx
Theres actually a CFL spiral thats only 5 watts, and has a output equivalent to a 30watt incadescent light bulb.
The 1 Watt LED bulb i have is Crap... ITs more like a night light. I use it for my upstairs hallway near the bedrooms. It doesnt provide useable light. But its such a low wattage that I could leave it on 24/7

I have a LED desk lamp from Phillips.
As a light source for adding light to the computer area, it is very good.
As a desklamp to read a book? its ok, but nowhere as good as a normal bulb -- it does not put out enough strong light even though it as something like 60 LED's in it.
