My bedside lamp is connected to a RF remote controlled power outlet. The control is not always ready to hand so I have come up with a solution using a fime porcelain coffee mug & a super-bright (500 lumen) CREE LED torch.
The torch has a pocket clip on it. I mount it with the body of the torch inside the mug. The switch end of the torch protrudes above the mug and is easy to find in the dark.
The bright yellowish light diffuses nicely through the walls of the mug.
