I had a light box previously (a Light Tracer 2). I was satisfied with it, as it met my basic needs. However, I was doing invitations for a wedding & the only way I could see my lined insert inside the envelopes was if I lettered at the very top of the box, where the light is brightest. That caused me to lean over the light box at a weird angle & it really hurt my neck.
For my birthday, I received a portable light pad and I'm totally in love!!! It gets super bright (and it remembers how bright you like it, so that when you turn it on, it goes automatically to the last setting you had) and it is easy to see a guide sheet even through dark paper! You need to treat yourself with one of these light pads! Maybe Santa will get one for you if you are very good!
