For my first ever Instructable, I am going to show you all how to make a light-box for movie posters, like at movie theaters!  Posters made for light-boxes are often referred to as double-sided, mirror sided or duratrans; their backs have a slightly faded mirror image of the front and they let light through.  You can get these off of websites like eBay, Amazon and collector sites.  You can also get the posters straight from the movie theaters themselves, all you gotta do is ask(mind you, many if not most theaters won't give them out to the general public).
  Commercially made light-boxes can cost over $400 new, sometimes $500!  This design will cost less than $100.
Knowledge in how to use power tools, electrical wiring and building is required for this Instructable.  Really you just have to know what you're doing.  If you don't know the basics, I can't help you.

Please ignore any inconsistencies with the pictures, I ended up having to redesign parts of it and some of the pictures may seem a little off.

<p>Great post! I was wondering, though -- wouldn't it be a good idea to use a metallic silver paint instead of white for the inside? </p>
<p>Thanks! I made a similar one for my child, he'll be so happy to get it at his birthday. But i had to secure all edges of the aluminium frame, because my frame was just plugged together and it loosened itself over time. Next time i buy another aluminium frame.</p>
<p>Hello! Where did you get the slim profile aluminum frame that you used in your design? we started building the wood box per your dimensions before we got the frame, and just now realized we can't find anything that looks like what you used. Hoping not to have to start over. Can you recommend where to get it from?</p>

<p>I got the frame from Hobby Lobby. They issue 40% off coupons regularly, so you could get them fairly cheap.</p><p>I believe it's just a standard size poster frame. I doubt that you'll have to remake anything.</p>
<p>Awesome project... Im looking for simple, cheaper, stronger and working with batteries one. I will try to next if i cant find.</p>

<p>i made a similar frame using LED and NO it's not as good looking as conventionnal fluo tubes. YAY for the FLUO :)</p>
Thanks a lot for a great instructable. I need about 6 frames so this will save me a lot!
Anyone out there know how to make one of these for on the side of a van? So i can advertise my wife's artwork website illuminated would be great in the winter months. <br> <br>Many thanks <br> <br> <br>
Thank you so much for this instructable video, I just built one, I skipped the backing part, I just built the box and mounted the light separate straight to the wall, IKEA sold cheap 27x40 black poster frame,I used piano hinge, I used T5 fluorescent lighting 36&quot; from home depot, came out really nice with mad hatter double sided poster. I did use plexiglass 1/8&quot; but could have used 3/16&quot; regular glass from local dealer, only 18 bucks but next time that's what i will do. Again thank you.
You could do this much thinner and closer to the wall using led strips!<br>It wouldnt be much more expensive, youve just gotta know where to shop :P<br>But fantastic instructable recently got a poster print of an art print and ive been looking for new ways to mount it, Thank you for the brilliant idea!
Nicely done!<br> <br> I like this idea although I am of the opinion that it can be done alot cheaper by using a posterframe from ikea and then hanging two lamps in that.<br> <br> I actually have cinemaposter size posterframe in my room with see through posters.<br> <br> I always buy them in my local cinema. They are quite cheap 5 euro for one :)<br>
