  • Fabulous light table for an amazing price
I bought this to use for making fabric applique pieces in quilt projects. I looked a long time for something large enough for my needs and for a reasonable price. Finally I came across this one, loved the reviews it had, and decided to make the purchase. I am very glad I did. It's easy to use, a beautiful light table with excellent light. It has a large surface, so any size piece you need to work with (or lots of smaller pieces) are accommodated on its surface. My only problem was it was supposed to come with a protective bag for storage, and it did not. So I made one, and now all is well. Hardly a thing to worry about. If you need a light table, you ought to get this one-or you can pay six prices for one that may or may not be as high quality. I'd buy this one again in a heartbeat. ... show more

  • Bright and light weight
The lighted surface of my 12” x 17” light box is actually 17 1/4” x 12 1/2”, surrounded by a 1 1/8” black frame. I like that the entire surface is the same level, no edges for the frame, so my papers always lay flat. Very thin because it plugs into my power source instead of using a battery. Nice & bright. I don’t see the tiny details clearly when I use my heavy Bristol vellum paper (probably could have 30 years ago!) , but I am able to transfer the design to my satisfaction. So far, I am very happy with this light pad. ... show more

  • Very handy for tracing
Bright, even light makes it easy to trace photos or sketches. It's also great for taking pictures of my art for digital editing and online posting.

  • Great, low price light box
The light box works perfectly. I knocked the rating down a star due to the terrible way it was shipped! Instead of being packed in a box with additional padding, the shipping label was slapped on the product box itself. The box was crushed and torn when delivered. I had to fully inspect and test it before I decided to keep it! Please fix this!! Also, finding a bag to store it in (since I can’t use the box) was tricky, but finally found one through Shabby Fabrics Quilt Shop. ... show more

  • Thin and bright!
This light board is so easy to use and it's thin surface brightens easily and is controlled by one finger touch. The smooth surface is high quality and has a cord that attaches easily. I've owned light box tables and this is so much better due to portability and easy storage.

  • Completely revolutionized my artwork!
I shopped around quite a bit looking for a "light box" as I was tired of drawing free-hand before painting. I'm very old-school, don't use gadgets for my artwork, just my hands, pen, pencil paint and brushes. I really just want to paint these days, not into drawing right now, and free-hand drawing is tedious and stressful at times which discourages me from painting at all. I looked at some light boxes at local stores and they were either too small, too boxy and/or priced too high. I have never used a light box so have nothing to compare it to, but this thing has met my needs and expectations! Its a nice and big lighted surface, super slim, the light is really bright. It will shine through 140 lb. watercolor paper which makes it super easy for me to draw my basic outlines before painting. I am cranking out the paintings sometimes at a rate of one completed painting per day! This thing has been a total game changer for my artwork, and well worth the price. When I wear this one out, I won't hesitate to buy another. LOVE IT! ... show more

  • Light not even across the panel
I took readings with a light meter and the brightness varies all over the place depending on which spot you are at. If your work depends on even brightness like DSLR scanning of film negatives, this would not be a good choice.

  • Functional and reasonably priced
This light box (or pad, I suppose) works well, especially considering its price relative to other light boxes I looked at. It has some minor cosmetic flaws (power cord plug is mounted slightly crooked, some small spots on the front panel allow light leakage, edges of plastic back panel are sharp/rough), but none of these affects the performance. I was not expecting the pad to be particularly bright or evenly lit, but it is both. The illuminated surface stays quite cool during use, although the black frame becomes warm in some areas. I bought this one instead of alternatives because it comes with an AC power cord instead of USB. I use it on a drafting table, and I wanted something that could be plugged into a wall outlet. The illuminated area is actually slightly larger than 12X17 inches; it will comfortably accommodate an 11X17 sheet of paper. I use a 2B pencil on 24 lb. text-weight paper, then lay a sheet of 100 lb. bristol board over that, and the pencil lines show through clearly. The thin profile (3/8 inch, excluding the foam rubber feet) makes this kind of light box so much more comfortable to use and easier to store than the traditional thick ones. ... show more
