Was at HomeDepot today buying light bulbs & learned a new trick from one of their licensed electricians. If instead of buying incandescent bulbs, you buy CFB's or LED's, you can put a brighter bulb in the fixture.
Here I was thinking that if the lamp was made for a 60W bulb, that meant that I had to buy a 60W (or less) equivalent LED -- that is, an 11W LED. Turns out that 60W is 60W. So I bought 19W LED's (equivalent of 120W incandescent) & omg! It's like noon at the equator now in my sewing area.
Probably a bunch of you smarties already knew this, but I thought I'd pass it along for anyone else who was sitting clueless in their dark studio space, wishing they had enough light to sew.
