I do a lot of my sketching on paper, and especially in the evening when it's darker out.

I have a nice lap desk but the light on it is absurdly small and crap. :/

Does anyone know of any bright quality clip-on lights that would be good for drawing?

Maybe looking around at a bookstore for reading lights?

Are you asking about the desk clip on lamps with multi LED lights? I looked into them, but the cost was way more than I could afford. I spoke with some other artsy people though, and you can basically make one as long as you're not wanting the magnifying lens some of them have.

You can pick up a desk lamp from a store that will take a standard light bulb, and then also purchase a LED light. I use something similar to have a light desk because they just put out that much light. I think the lamp ran me about 5 bucks, and the light bulb is around 11-9 depending on your lamp's wattage rating (but is also replaceable in the event it goes out, the lamps I looked at the replacement bulbs were whoa expensive :L ) If your desklamp just takes standard blubs already, you can just skip to the LED light.

Said light bubl/desk lamp All the light in this photo is purely from the one bulb or fish tanks, that's how bright these bulbs are. I use them to transfer sketches through on to watercolour & bristol paper. (If you use this trick, do NOT look into or at the light, in fact I believe there is a warning on the blub not to either)

If you can light the whole room though, that would be more ideal. I use daylight bulbs in my studio, to avoid having the gunky orange tones to everything. But it seems like that's not possible from the fact you're using a desk lamp currently.
