Review on Enhanced Medalight LP-100N 5 x 4 Inches LED Light Panel for Ultra-Thin Negative and Slide Viewing by Rodney Harris

This is a VERY bright little lightbar. Awesome for viewing my 4x5 slides. But I also use it in conjunction with my iPhone to view multiple negatives at once. If you want to turn your iPhone into a negative viewer, go to Settings: Accessibility: General: Accessibility Shortcut: Classic Invert Colors. You can then press the home button three times and your screen images will be inverted. Press the button three more times and your screen will return to normal. You can then use the zoom feature to take a closer look.
