Save on everyday low prices. Review: Perfect upgrade - I have screen printed since 2009. My exposure my original exposure unit needed to be upgraded. I was nervous... without being able to touch and personally inspect the unit, BUT no worries here. This unit is exactly as described. Heavy duty. Well packaged. Very satisfied. Review: Not happy - First of all, I just found out that the item was used which I’m not too crazy about. Opened the box and the product was scratched to no end, dented and also has a blown fuse. The lights inside were knocked out of place. Had to order new fuses just to be able to try it to see if it even works. Not looking good. It seems like it blew a fuse as soon as I plugged it in. The buttons on it are in Japanese so it’s hard to know exactly what you’re controlling. Not a good product. Don’t waste your money on this product. ## Features - 【High Efficiency】There are eight 20W UV burning LED Lamps (total power 160 W). Normally can be used for about 10,000 hours.

When the emulsion is dry, place a positive print of your image on the screen. Once you burn the screen, the emulsion that did not get any UV will wash out of the screen exposing the tiny pin holes. The surrounding areas that were exposed to UV will be cured. Hence the ink will pass through screen onto your substrate. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WDGVKXF | | Best Sellers Rank | #764,454 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #1,314 in Screen Printing Accessories | | Brand | TECHTONGDA | | Brand Name | TECHTONGDA | | Color | Purple | | Customer Reviews | 3.3 out of 5 stars 11 Reviews | | Item Dimensions L x W | 21"L x 21"W | | Item Form | Bolt Of Fabric | | Item Length | 21 inches | | Manufacturer Part Number | 006854 | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 21"L x 21"W | | UPC | 748497501593 | | Weave Type | Plain | ## Product Details - **Brand:** TECHTONGDA - **Color:** Purple - **Item Form:** Bolt Of Fabric - **Product Dimensions:** 21"L x 21"W - **Weave Type:** Plain ## Images ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 1](https://m.media-amazon.com/images/I/71P-IOpM5FL.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 2](https://m.media-amazon.com/images/I/71dcfnkvF7L.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 3](https://m.media-amazon.com/images/I/71imlj9sGhL.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 4](https://m.media-amazon.com/images/I/71zvxwAjQ5L.jpg) ![TECHTONGDA UV Exposure Unit 20x24 Inches Silk Screen Printing LED Light Box Plate Burning 110V - Image 5](https://m.media-amazon.com/images/I/71qexfB9SqL.jpg) ## Questions & Answers **Q: My screens are 20x24 will this unit work?** A: The maximum external size of your screen frame must be within 25" x 21” **Q: This unit was damaged, do I have to pay for the return?
