At times if you think that you need extra light on your laptop keys then you seriously need to either see an eye specialist or get yourself a laptop tray light such as the one attached to a tray in the picture below.
It is not a fancy looking laptop tray as it has a built-in light that runs on 3 x AA batteries, a cup holder for holding your drink and a pen holder. This built-in laptop tray light has 5 LEDs which produces enough light so that you can work easily in low light areas within your house.
It is sufficiently padded so that you can either place it on your lap or any other firm place such as your bed mattress or even your couch
You can easily get this cheap Laptop Tray for under £15 in UK.
